Hello,

I got myself a DS last month, and a flashcart last week... Looking through the projects, I liked Licks Media Player (ipod-like player) very much, but unfortunately it was discontinued :-(

So... I just decided to finish it ;-). In the end, it became a complete rewrite. No more C++, only pure C. At ths time, I only have some basic functionality, WAV playback (files must end in .wav) and libmad playback (files must end in .mp3).

I need some feedback, if you can try, just download at http://www.cecm.usp.br/~lucas/lmp-ng/ . Theres two versions, a .nds and a .ds.gba. Both are compiled with libfat DLDI, so you can patch if your flashcart does not work out of the box. The source is also in the same page.

Oh... And this is my first homebrew, so expect many bugs.

You can use START to alternate between console and graphics mode.

I'm mostly interested in feedback regarding sound quality (how does it compre to other mp3 players for ds, e.g. moonshell) and stability issues.

There's 3 different play modes, mode 1, mode 2 and mode 3 ;-) SELECT alternate between these modes, but you have to PAUSE/UNPAUSE so the mode will be applied. If you happen to test, please, send feedback on which one you think sounds the best. (these modes basically do some linear oversampling, just like moonshell).

Also, send your wishlists, I'll implement the most popular features first!

Feature requests? OK...
-M3U playlists
-Hold feature that disables all buttons except whichever button turns it off (eg Select) - disabling L and R isn't enough as with the shape of the Phats it's possible to accidentally press other buttons when the lid is closed.
-OGG support

I didn't really hear a difference between the modes when playing back mp3s, but when listening to some wav drumloops (these here), I noticed some clicking, especially in modes 1 and 2. It wasn't 100% reproducible, so I think it's a buffering problem of some sort.

I'm really happy that someone is continuing this great project, so keep up the good work, lucas!

Awesome! I would really want to know how you managed to get the sound right (without clicking). I tried many different solutions before I finally gave up.
Anyway, good job! Keep it going!

Great job! The music is much better, although I still get clicks on all 3 modes. (Mode 2 seems to be better)

Is the menu supposed to work? Because it seems I can only scroll, and not enter a submenu.

Feature requests:
Ogg Vorbis
Unicode
Sleep mode
Soft reset

Probably a bug either in winrar or in your browser.

Neither - other files can be unzipped. But I will try Firefox just to be sure.

Just because something works on some files of some types doesn't automatically mean it will work on all files of all types.

I just tried it in firefox, works fine. In IE, it seems like it decides to uncompress the files automatically, but not remove the .gz extension. Try just renaming them. I think I've seen this bug in IE before.

try this
http://zenixstudios.com/f_new/f/lmp-ng-alphaace.zip

The server is misconfigured. It's sending Content-Type: text/plain and Content-Encoding: gzip for the gz files. You have to right click -> Save Link As with Firefox, because it opens it as decompressed text otherwise.

IE indeed decompresses the file (because the server is telling it that it is gzipped text), but neglects to remove the .gz from the extension. Removing .gz from the filename and using it as-is will work fine.

The .tar.gz has no such problems, though.

Ok, time for a new release. Grab at the same place http://www.cecm.usp.br/~lucas/lmp-ng/.

I'm labelling this alpha2 version, it's still very experimental.

New feature: playlist support. Some bugfixes and some rewrite in the graphics code.

For using playlists, you MUST use relative paths, no absolute paths. Also, you CAN'T use ".." in your paths (e.g. /abc/d/../e).

I've moved to more common .zip files for the precompiled binaries, so no more confusion!

@0xtob: there was a small bug in the oversampling code when dealing with 1 channel stream, I think that was the cause of the clicks. Should be fixed now.

@felix123: the menu wasn't supposed to work. Now it is! ;-)

@Lick: I tried many different methods to get the sound click-free, but each one had some prolems. In the end, the best that I could do is to use a triple-buffer in the ARM7, so while ARM9 is busy decoding there's still 2 pieces in memory to play. This reduced greatly the clicks/noises, the two processors don't need to be 100% synchronized, cause even if the sound enters the next buffer, it won't cause clicks. You shold take a look at arm7/source/sound.c, functions pcmplay() and InterruptHandler_TIMER1.

It is great you are taking over this project. I think LMP is a great idea too. Thanks for compiling with dldi support.

My results on R4:

old version of LMP:

nds loads, I can hear click sounds from menu, but when I select Songs, it freezes.

alpha 2:

loads fine, all mp3s on card are found and avail in songs.

Nice to see more work on this!

Gave it a quick spin.

Loaded fine on a DS-X with firmware 1.1.0
Played a 192kbit mp3 very well, clear and crisp

Some graphical corruption on top screen, flickering lines and repeated gfx
scrollwhell behaviour is not smooth!

If u want I can make you an icon for it!
Just an itunes conversion, tell me the format & i'll send it to u.
Is a 16 color transparent gif ok. or do u preper a bmp?

Just uploaded another build.

Some bugfixes and power save mode (turns off backlights).

I tried to implement ogg support (using tremor), but something is wrong. The code runs fine when outside the interrupt handler, but when I put it inside the interrupt handler, it just hangs (using IPC_SYNC_IRQ). Maybe its some stack corruption, but I don't know. Tried to debug, but I don't know arm assembly, so debugging is very hard :-/ If someone knowns what might be happening or want to fix it (patches are welcome! :-)) then please, let me know.

You need to apply those fixes to the Tremor code to avoid some memory leak issues.
You may also want to take a peek at the Moonshell vorbis plugin (which has above fixes already); it might help you figure out what's wrong.
http://utorrent.com/mspv10_ogg_20070113.7z

Very impressive. I look forward to updates. Since you asked for requests I'd like to suggest a volume boost and shoutcast/icecast support. I love to listen to wefunk radio on DSOrganize but it always crashes. I like this player better anyway.

Thanks for the references, implemented the first fix, the second is not necessary when using the lowmem branch of tremor (even on the main branch of tremor, I don't think it's necessary: that sortindex vector is allocated with alloca, so it should be freed when the code block finishes, as it's on the stack).

Well... even with that fix it still dont work while running inside the interrupt. I just did a quick look at the moonshell code, and it appears that moonshell don't decode inside the interrupt (it just copies the buffers to the arm7), while the actual decoding is done in the mainloop. I'll try this approach tomorrow, but it needs some big rewrite of the sound code :-/ And I still don't know why it don't work this way...

It hangs when you try to enter the Song menu if the song's ID3 tags are not in ascii.

Just noticed the clickwheel is also mapped to the dpad and buttons. Nice addition.

Additional feature request:
Streaming ASX

If you're declare big structures in your functions like:
void function()
{
ImABiggy bigstruct;
}

then it's better to use a global (or classmember) or assign some RAM to it beforehand. It fixed some issues I had with the stack. Also I think it's better to do the decoding in the mainloop, as interrupts should be as short as possible. Tremor is actually much easier (and faster) than libmad, so yeah, a bit more work and it could be done!

I briefly tried it yesterday - so far no complaints, the sound quality is good and the mp3s on my flashcard were automatically found (I had some trouble with that on Lick's original build).

A shuffle function would be most useful.

Pretty good on the playback :)
Though, when the ds screens turn off when it's open, they don't completely turn off. I'm wondering whether this is the same when the ds is closed. Might lessen the battery life?

As for the wishlist:
-Sort by Artist/Album

-Album art support either by a jpg in the album folder, or by the integrated Album pic in the mp3.

-Equalizer

-streaming music from wifi

-Don't think AAC support is possible, Moonshell can't even do it right. But worth asking? heh

AAC is not possible right now because the decoder is far too slow. You can decode maybe 96kbps LC-AAC at fullspeed at best....
Of course, someone with some coding skill could probably improve that.

Features I'd love to see

-Album Art
-Songs Alphabetized
-A Artist list (in the music folder under songs play lists and now playing are)
-Playlists
-Video Support, and photo support
-A way to froward and rewind music & videos
-An optional Black skin (Or other iPod colors)
-AND a volume increaser, If possible don't make it like moonshell(the lounder you make it the more the quality of the songs goes away)

http://licklick.wordpress.com

I couldn't tell too much of a difference between the different sound modes, other than mode 3 seemed to bring out the treble in the rock mp3s. The quality is good overall. As good as I've heard it get on the DS anyway. Stereo 44khz 16bit, no clicks or skips. I haven't tried with headphones yet, so that might be a different game altogether. I'll edit that in when I get around to it.

@lick:Try not to be so hard on them. There are only a couple and the first post specifically requested that people post their wishlists.

didn't mean to be selfish. He says we can ask for features...
"Also, send your wishlists, I'll implement the most popular features first!"

lucas, I found another leak in Tremor that's specific to the lowmem branch.
http://lists.xiph.org/pipermail/tremor/2004-April/000965.html

Keep up the good work with this, might just replace Moonshell as my main audio player.

Just got ogg vorbis working (moved the decoding out of the interruption)! I'll post a working build later.

About the features, no problem asking, but that don't mean I'll implement it ;-) If you _REALLY_ want some feature, well... you have the code! Just implement yourself and send a patch, so everyone can benefit.

I'll comment on some of the features:

- FLAC support: I'll try to get this working. Don't know if it's possible, but most of my collection is in FLAC, so that's a feature I want ;-)

- Increased volume: I'll get this working soon. However, it's not possible to easily increase the volume without losing quality. I'm not a specialist in computational music, so I don't even know if it's possible at all (if someone know, please let me know).

- Seeking support: Will get this working soon. Unfortunately, there's no easy way to seek in VBR mp3 files while still having a good time display :-/ The only way would be to create a seek table, but for that it's necessary to decode the whole stream before starting the music, but the DS isn't fast enough to do this (that's why I still don't have seeking support).

- Video support: Won't happen anytime soon. It's VERY hard to keep things in sync in the DS, so I don't even want to try this.

- Other features: possible, but not in the first version.

So, my current roadmap is this:

- FLAC support
- Increased Volume
- Seeking support
- Alpha version
- Feature freeze
- Beta Version
- Release Candidate
- 1.0 release

Did you implement that additional memory leak fix? Or was it not applicable?
Have you implemented ID3v1/v2 support? I'd implement it, but I'm not a coder. :)

You might want to look at FLAC 1.1.4 alpha's source: the decoding speed was improved significantly over 1.1.3, especially on processors like ARMs. Probably need to nab it from SVN.

Basically, you need to implement soft saturation to avoid clipping (but it still distorts the audio) when raising the volume.
And when lowering volume, you can simply use the hardware to do that and save some CPU. That won't sound any better, though.

I have no idea how Moonshell does this, but it seems to have no issue seeking properly. I'm sure it's not sample-accurate, since that requires brute forcing the file. The Xing and VBRI headers (99.9% of VBR MP3s will have one of them, Xing being more common since it's what LAME uses)have pseudo-seek tables that give you a rough estimation of where to seek to. With that, you could simply brute force your way to the exact sample you want, though I think it'd be overkill for the DS.

If you ever wanna give it a shot, Moonshell's source is a good place to start. :P I've always wanted DPG to use Vorbis instead of MP2...

I could just seek to a position in the file, libmad takes care of finding the next frame. The problem is that I won't have an accurate timer to display. Don't know how moonshell does this, but it doesn't have a timer!

FLAC is better on hard drive players than on flash memory players. I don't know a lot of people who have modded their CF adapters to accept a Hitachi Microdrive hard drive, but I'm told that one of the MAX Media Players comes with a 4 GB CF hard drive.

Yes, it's possible to distort an audio signal such that segments at low volumes are boosted and segments that approach the - and + rails are not harshly affected. Pass each sample through a saturation function that does not have a corner at full scale. I describe four such curves; with a graphing calculator, you can probably devise more:

One saturation function starts by plotting the following functions on y=0 to 1:

y = 1 - (1 - x)
y = 1 - (1 - x)^2
y = 1 - (1 - x)^3
y = 1 - (1 - x)^4
y = 1 - (1 - x)^5

So where g is the gain (amplification factor), and 1.0 <= g, the expression for the positive half (quadrant I) of the saturation function is y = (1 - (1 - x)^g. The expression for both halves (quadrants I and III) is y = signum(x) * (1 - (1 - abs(x))^g, but ordinarily you'd generate a lookup table from the function for the positive half and then copy and rotate it into the negative half.

Another saturation function that doesn't need fractional exponentiation using floats is based on a cubic Bezier curve with control points (0, 0), (1/3, y1), (2/3, y2), (1, 1). The values y1 and y2 are set such that the first control point sets an acceptable gain for small volumes and the second eases saturation into full scale. The equations for quadrant I are as follows for 1.0 <= g <= 3.0:

Where 1.0 <= g <= 1.5: y1 = g / 3, y2 = 2 * g / 3, giving y = g*x - (g - 1)*x^3.
Where 1.5 <= g <= 3.0, y1 = g / 3, y2 = 1, giving y = g*x + (3 - 2*g)*x^2 + (g - 2)*x^3.

Yet another is arctan(g * x).

Yet another is sin(clip(g * x, [-Pi/2..Pi/2])).

I'm no expert on the MP3 bitstream format, but can't decoding the stream for the number of bits in each frame (counting the reservoir) be decoupled from decoding the stream for MDCT coefficients and transforming them into the time domain?

_________________
http://licklick.wordpress.com

i know you want us to stop with the feature requests, but an automatic poweroff at end of a song/after x amount of time would be awesome

AAC: DSOrganize does a great job of streaming 40kbps AAC+ (which sounds at least as good as 128kbps MP3), but it's very unstable. I always like to say there should be at least two tools for any given job, in case one doesn't work quite the way you'd like. So... any chance of this happening?

Increased volume: I'm pretty sure it's not possible to software-amplify without losing quality unless you have a very quiet sound. However, if the DS's full volume isn't loud enough for you, you're probably in a fairly noisy environment (or have bad ears) and won't notice it anyway. ;-)
BTW, I noticed using software amplification and turning the hardware volume slider down helps to save battery power. Those speakers are really power hungry.

Seeking: I think what Moonshell does is simply play really fast and not actually output the decoded sound. It doesn't have an actual timer, only a progress bar, but it seems to be accurate.

FLAC: A nice feature, but is it worth it? The DS's sound hardware isn't the greatest, you probably wouldn't hear much difference from a good-quality Vorbis file. And since the DS uses flash memory (or microdrives at about the same capacity), it may not be feasible. One CD's worth of FLAC files is ~300MB in my experience.

Oh, and please don't automatically turn on the backlights when the program starts! Ideally the program itself would have a way to control them, but this isn't really necessary. However, it's annoying to turn the lights off, then run a program that just turns them on again.

Wow lucas, very nice job. Oh and thanks to Lick who started it :). I would offer to help as well, but all I know is java :-\.

Oh yeah, it turns out when I switch to the third play mode, LMP-ng just freezes completely. 1 and 2 work perfectly though... I'm using an M3 Simply with an R4-DLDI patched version of LMP-ng btw.

Thanks for your explanation, it was very helpful.

However, I'm running into some problems implementing this: first I tried to implement it directly into the ARM7, hoping it would be fast enough to do it in real-time. Unfortunately, it's not fast enough. Then I tried to create a look-up table, as you suggested, but it takes more than a second to create such table on the ARM9, which makes changing volumes take too much time. The last thing I tried, which worked, but wasn't optimal, was to precalculate the tables and include them on the binary... But each 16 bits table takes 128KiB, and having, for example, 8 such tables, would enlarge the binary by 1MiB, and take 1MB of the main memory :-/

Do you know any other way to do this? Or is there any function which is integer-only and could be used in real-time?

I was thinking of implementing these functions using fixed-point integer math, but that's a lot of work, and I don't even know if it will work...

I'm no expert either, but even if that could be done, and say, the MDCT takes 95% of the decoding time of the MP3, it would still be painfully slow to sample-accurate seek in a 30-min MP3 :-/

I guess the best solution here is the one Firon commented, which is relying on the Xing VBR header to seek with a reasonable accuracy.

Just uploaded a new relese. Grab it here http://www.cecm.usp.br/~lucas/lmp-ng/.

Many new features! Hope I remember everything, here it goes:

- Ogg Vorbis decoding support
- FLAC decoding support (but not FLAC in OGG container)
- Soft-volume control
- Progress bar
- Seeking support
- Hold button (select)
- Control with L/R buttons when lid is closed
- Gapless playback

I've removed support for .wav files. It was there mainly for debugging (doubt anyone really uses it), and I've removed as part of the rewrite of the ARM9 sound code.

Now it's bug-fixing time. Please, only report bugs. No more major features will be added till version 1.0.

Enjoy!

Great work! The volume can be so loud I don't dare to turn it up to 100%. ;)

- It still hangs if the ID3 tag is not in ascii
- Up and down are mapped to the wheel in the menu but L and R in the Now Playing screen?
- The volume bar moves smoother when playing MP3s compared to OGGs?

I hangs in the Songs screen? Or when starting? Strange, I tough I fixed this (non-ASCII chars should appear as ?). Can you provide more info on how to reproduce this?

Quote:

I though it was more natural to seek with L/R... I can map to both next version ;-)

Quote:

That smoothness depends on the how much CPU cycles the decoder is letting us use... I think its better to have a non-smooth screen than to have a non-smooth music playback. It certainly is possible to optimize the screen drawing code, but I need more experience with DS graphics hardware.

Sorry. Should've provided this sooner. Here's a zip file with a MP3 and an OGG. They are silent. Both are tagged with the Chinese characters "one two three". The MP3 hangs, but the OGG doesn't (characters don't show up, as expected). It hangs at the "Music" menu right after you press the right button with the cursor over "Songs".

That makes sense. It's not a problem at all.

Hello Lucas,

I wanted to ask you if you could do this:

When DS is closed, holding L and then R will change the song.
When DS is closed, holding R and then L will stop the song.

This would be really useful, because I don?t like to open my DS to change or stop a song ;D

(In Moonshell it?s the same)

Edit: and shuffle would be awesome too.

Well... if you tried it... it is exactly as you described. You have to be on the "Now Playing" screen when you close the DS, though.

Thanks Lucas, from now on I?m going to use this player, and not moonshell

Its a really awesome piece of software. Thanks Lick&Lucas :)

Agreed, I love it! Thanks for the good work, guys!

I have a suggestion for the progressbar, I'm not sure how you render it right now but..

You can take the repeated image (lightblue-darkblue-lightblue) and use modulation to get the current x offset, so you can tile that repeated image horizontally.

Code:

for(y; y<height; y++)
for(x; x<width; x++)
dst[y*width + x] = progressbar[y*tilewidth + (x%tilewidth)];

This way you can save some memory if you render in ExtRot 16-bit mode.
You can also animate the progressbar ilke real iPods do, by adding an offset and the modulate it:

Code:

for(y; y<height; y++)
for(x; x<width; x++)
dst[y*width + x] = progressbar[y*tilewidth + ((x+OFFSET)%tilewidth)];

if(playing)
OFFSET++;

This will make the progressbar animate to the left. :)

You can also optimize the font rendering code a bit by pre-greyscaling and pre-setting-bit15 (if pixel is visible) the font-data, instead of doing it on the fly.

You might also want to compile as ARM code (that should be faster). Simply edit your Makefiles on the line: '-mthumb -mthumb-interwork' and remove the first '-mthumb'.

Code:

ARCH := -mthumb-interwork

I'm not sure if you already enabled ARM optimization for mad and tremor yet. But you can by defining _ARM_ASSEM_ (tremor). Add '-D_ARM_ASSEM_' after '-DARM9' in your Makefile. The same for FPM_ARM (mad).

Code:

CFLAGS := $(INCLUDE) -DARM9 -D_ARM_ASSEM_ -DFPM_ARM

Great work on the updates. I guess LMP now stands for Lucas' Media Player. Hehe..

However, I'm running into some problems implementing this: first I tried to implement it directly into the ARM7, hoping it would be fast enough to do it in real-time. Unfortunately, it's not fast enough. Then I tried to create a look-up table, as you suggested, but it takes more than a second to create such table on the ARM9, which makes changing volumes take too much time.

How many entries are in your lookup table? Did you use float or fixed arithmetic to build the table? It appears you tried to make an entry for every single 16-bit sample value in -32768 to 32767. So why not make a 257-entry LUT and use linear interpolation for the in-between values? Untested code follows:

Code:

signed short gainLUT[257]; // [0]...[255] for -32768 to 32512

inline int gainLookup(int sample) {
unsigned int lutIdx = (sample + 32768) >> 8;
unsigned int gainSub = sample & 0xFF;
int lowEntry = gainLUT[lutIdx];
int highEntry = gainLUT[lutIdx + 1];
int fractional = (highEntry - lowEntry) * gainSub;
return lowEntry + (fractional >> 8);
}

Hi,

If I want to play music that?s 320 kBit/s, it freezes after the or before the song.

@Jabba:

Try to format your Card and then try again, worked fine for me like this too. (I think this player is not stable enough to handle File Allocation Table Errors )

@lucas:

Could you please add a file hide support to lmp ? I ask this because I always get my Moonshell startup sound (which I don't want to hear anyway) I did hide the startup.mp3, but Lmp lists it anyway, beneath this I like your (and licks) program pretty much

I think this is because neither moonshell nor DSOrganize scans your entire device for music files. They just open the folder when you click it.

Wow! Great work.

I saw one you main priorities was to implement louder volume, which you seem to have done already. I have not tried it yet. But as soon as you mentioned it, I thought of implementing the vlevel algorithm. If you do not know about it, have a look at http://vlevel.sourceforge.net/

You can try it with foobar2000. They have a vlevel plugin in their forum.

If you have corruption on your card, download MCTool on scdev.org's homebrew forum. It's DLDI compatible and can repair FAT errors.

Not possible... This code uses a LOT of floating-point math, and the DS have no FPU-unit... And the DS is not fast enough to emulate the FPU while still playing the sound.

Hello Lucas,

I wanted to ask you if you could do this:

When DS is closed, holding L and then R will change the song.
When DS is closed, holding R and then L will stop the song.

This would be really useful, because I don?t like to open my DS to change or stop a song ;D

(In Moonshell it?s the same)

Edit: and shuffle would be awesome too.

Oh, this reminded me of something very important. I know you said no feature requests for the next version but this should really only require adding/changing one line of code (mask out the button flags). I found a problem with Moonshell is when the lid is closed, the L and R buttons are disabled, but others are not. Could you please make the Hold feature disable every button except Select (to disable hold, of course)? See, with DS Phats the A button is very close to the edge of the lid. It's possible (and happens to me fairly often) for the A button to be accidentally pressed when the DS is in your pocket with the lid closed. I don't know if this problem applies to other buttons (D-Pad left, probably), but obviously if you just disable every button, you won't have to worry.

Great work BTW, this may soon replace Moonshell as my primary music player. (And if you add stable AAC+ streaming, it may even replace DSOrganize as my primary streaming music player.)

The hold button (select) currently disables every button except select and start (goes to console).

I could just seek to a position in the file, libmad takes care of finding the next frame. The problem is that I won't have an accurate timer to display. Don't know how moonshell does this, but it doesn't have a timer!

Does it at least give you the frame number when seeking? A frame in MP3 is a specific number of samples, so with that you could calculate the time pretty accurately.

If you know the current offset in bytes, you could do this calculation:
current_time = current_bytes * (total_bytes / total_time)

The problem here will be knowing the total_time beforehand. It might be in the tags, or else you can roughly calculate it. MP3Infos source might be interesting to read through.

That won't give you a very accurate time with ABR or VBR. It might not even be that accurate with CBR because of the bit reservoir.

The GP2X's built in MP3/OGG player can display the total time and the current time of a song. Dunno if it's in here, but this is the SVN repository for the open source parts of the GP2X's firmware.

Oh, and I've only had an issue with one song - it claimed the length was 1 second. Still played OK though.

i just wanna post some feedback/bug/or maybe im just a noob.

im using supercard sd with f/w 1.7 and when i tried out the latest build (alpha4) i cant seem to get it to start. its stuck at the loading screen - "starting" and it wont startup.

fyi, i have only a few audio files in my flash cart so its not that its loading too many songs. i tried patching with the dldi for scsd using the GUI version for windows and its the same thing.

am i doing something wrong bcoz i could use lick's version (before it was revived) with no trouble. thx in advance.

awh85 is having the exact same problem as me, because i formated my card i only put one song on it to test it so i dont know whats wrong with it.

hmm... try the newest version of DLDI Patch ?

ah ! That reminds me of something !
If I let lmp play my music all the time it locks up after some time ( takes a little bit lets say ~10 Minutes, thought it may vary on other cards)

I use a Gbamp CF 2 and I just downloaded the default .nds and it worked right off (after I formatet my card, because I had some Errors in the FAT Table thanks to DSOrganize' Copy function )
_________________
Starcraft DS ?

Using an R4 slot1 cart btw
Found a bug in alpha4:
Played three 320k mp3's. And they all make your player freeze when they end. Also tried two 192k mp3's and it seems to skip to the next song, but they also freeze

I also noticed in alpha3 some mp3's started to get scratches on the 2nd consecutive track, but can't test that out since each mp3 freezes at the end :)

About OGG, I played a 19min song and played just fine :D

A suggestion..i know you're no longer wanting asking about features, but besides adding moonshell-style L/R like others have asked, maybe have seek on the touchscreen like moonshell and adjust that way, or hold the REW/FF on touchscreen to determine whether they skip to next song or seek.

overall it's a very promising player, keep it up

UPDATE: for some strange reason, the freezing bug disappears if i have an FLAC file in the playlist. odd. taking out the FLAC file returns the freezing bug..

@ pas

Yep, latest version

New version! http://www.cecm.usp.br/~lucas/lmp-ng/.

New in this version:

- Shuffle mode
- Fixed a bug that may cause freezing when mp3 is finishing
- Animated progressbar
- Much better quality volume control

Known problems:

- FLAC playback have some problems

If you are experiencing freezing, try formatting your card and copying everything again. That solves a lot of problems with corrupted FATs. If it still doesn't work, try holding A or B (or both) when starting the program (that'll disable loading of ID3 tags and playlists, respectively).

If you're still experiencing problems when starting, hold START while starting, and post the last message on screen.

Hi Lucas,

First of all I would like to tell you that you're doing a GREAT job with this thing! My compliments!!

I use the simply 3D card and get the following while pressing start:

display ok!
starting ...
starting sound ... OK
starting fat ... OK
scanning device for music files ...

It seems to freeze there...
Should I put my mp3-files in a specific folder or anything???

Thanx and keep up the good work!!!

@Maupi: No, they don't need to be in a special directory... Did you try to patch it with DLDI for your M3 Simply ?

@lucas: If you need help with that file attribute thing, I suggest you to ask Dragonminded, because his DSOrganize supports that too so I guess he should know how to.

Have you patched with the correct DLDI driver? This means libfat is not working with your flashcard.

No, try re-formatting your card. If that still doesn't work, try hold A/B when starting.

Holding A on startup did solve the freezing problem, but it's not an ideal solution.

For some reason, the same characters are encoded differently in the two files: one as Big5 and the other as unicode
MP3 Big5 0xA4 40 A4 47 A4 54
OGG UTF-8 0xE4 B8 80 E4 BA 8C E4 B8 89

I hope this will help you solve this problem. thanks.

Can you try formatting the card and trying again (it worked for me)? I believe this is a bug in libfat or newlib (not sure yet). I could not reliably reproduce this bug :-/ There's something in your files (and probably libid3tag that I'm using to read the ID3 tags) that helps the bug to appear, but it's not 100% accurate.

I spent at least five hours trying to track this bug, and I've found a bug, but I don't think it's the one yet. I've reported the bug to chishm, it was a bug in newlib, and it will be fixed in the next devkitARM. The big prolem is that this bug is not in my code, so, it's very hard to track it down.

Just a note to say that the development looks great. I hope that you and others keep up the good work and continue the development.

I need to try formating the flash drive this evening and see if it fixes the "freezes" I have when using the program.

I may see if I can learn to program for the Nintendo DS and add some features of my own. It has been a while since I have programed but I may be abel to remember.

Thanks and keep up the good work!

Thank you Lucas, I'm very pleased to see this project in good hands ;)

But I found a very little bug

Bug report :

When I change the volume, and if I press the START button, the volume comes back to the default level. Not very serious, but good to know :-)

[Edit] Oh and did you add the reset function ? If yes, what's the key to push on to have it working ?

Thanks again for this good software !

Cheers,

Darkgilson

This is generally not a problem. It just means libmad skipped some part of the file (probably an ID3 tag or a corrupt frame

This is another recoverable error. Probably you were seeking.

If you're not having an "unrecoverable error", and your music is playing well, then there's nothing to worry. This messages are just warnings, nothing to be concerned.

wow that was a quick reply!

Anyways, for my problem, I believe I do get unrecoverable errors. But the debugging messages go by too fast to see.
The music is beyond recognizable. I just converted one of my mp3's to ogg and it works fine!

The odd thing is my mp3 collection works good in moonshell and DSOrganize. And they worked in your alphas. But this latest beta did not work. No matter what I tried. Well I LOOOOVE the seeking with the progress bar (with L & R) wow! very sexy!

thanks so much!

Marty

lucas: Have you thought about using the Helix mp3 decoder instead of libmad? Should be a decent amount less resource intensive. https://datatype.helixcommunity.org/mp3dec

M3 Lite (using a 1 GB micro SD card made by PNY)
It works great but after playing at least four songs then trying to go back to menu and picking a new one. When you click on the new song to play it, the player plays the first note then starts to play that same note over and over again and freezes entirely.
Besides that it only freezes up on me after j have listened to it for more then 40 minutes.
GREAT player, i use it even more then moonshell now for music. i can't wait to see the final version.

Great !!!
After formatting my card the freezing problem is gone !!!
Thanx all and keep up the good work !! ;-)))

could FM radio or any kind of radio be made into this program?

Well, DSOrganize can do it, so it is possible to do. I played an MP3 and a Vorbis internet stream today.

first of all, awesome piece of work! many thanks for you hard work and time you spend so far.

second, i'd like to request a feature. i know it doesn't really belong to an ipod, but i want it so badly and if it where in your software, that would be the so cool.

i want an alarm clock, which wakes me either to a playlist or a single file. but after choosing the wake time, the ds has to shut off! this is most important, because ist has to be left open for the amplitude to be high enough, and no power consumption through the night.

do you think this would be possible?

Zero power consumption would require actually turning the system off, which means the only way for it to wake you up would be to have someone come in and turn it back on. However, you can turn off as much as possible (screens, backlights, sound etc), put the ARM9 in super-low-power mode (turned off basically), and I guess just have the ARM7 spend all its time idling. Use a timer interrupt on the ARM7 to turn it back on and activate the alarm. This appears to be what Nintendo's does. From what I've heard the battery can last 2 weeks in this state (obviously not in the alarm clock, but e.g. in sleep mode in a game, which is the same thing using the keypad interrupt).

And that wouldn't be FM radio, which would require a hardware add-on.

@hyperhacker:

well, i know zero power consumtion isn't possible, but what you say sounds good enough! please make this happen :)

there's a hardware fm radio addon for ds. it's retarded it sticks out. you can probably get a smaller fm radio that's not for ds. it's just not worth it.

As I've said before, my MP3 player the size of a lighter has an AAA battery, backlit LCD display, 1GB flash ROM, headphone jack, line-in jack, microphone, USB connector, enough processing power/dedicated hardware to encode and decode MP3s, and an AM/FM radio. I'm sure a lone FM radio can fit into a DS card or GBA cartridge.

[edit] Wrong type of battery.

Something like this one?

I couldn't find it on the site that Popsci listed it as being on, but I'm sure that it can be found somewhere.

*Edit: Found one: click.

If the radio cartridge has its own headphone jack, then it's just using the GBA/DS as a power source. In that case, why not just carry a separate radio?

You can still make it use the GBA/DS's screen for a GUI. That's what the Play-Yan does, and it has its own headphone jack too.

Just one quick thing to note: the touchscreen recognition is acting somewhat strange. I have to hit the same place several times before it will recognize what I want it to do (next, previous, play, etc). I can press Start and see that it is indeed receieving coordinates for my presses, but it doesn't do anything until the third or fourth try. The Alpha3 version did not do this (haven't tested anything between Alpha3 and the latest version). Scrolling the scroll wheel works fine; it's just the single tapping that doesn't seem to register.

That said though, this is turning into quite the application. Keep up the great work.

BUG REPORT:
when scrolling, the backlight was turned off in x seconds T_T (fix timmer pliz ^^)
Request :
center button not only select song, it should play selected song also . !!!
play/pause button :
[1] : song menu : play selected song ( cant go to next song automatically )
[2] : other menu : --- (song playing) pause playing song
--- (song paued)Go to nowplaying and resume song
--- (song stopped when finish [1] ) : Go to shuffle menu ^^

Setting menu : just need backlight level/timeout , volume limitted, lock, fast-booted Mode (see below), about , Card infomation, ....... (if you need more idea, contact me ^^)

Fast-Booted Mode ----[ON] : turn off refresh music library when boot up
----[OFF] : opposite above ^^
so that, you should store library to a text file (TAG info included, no need to read tag again ^^)

lasted, sorry for my english ^^

Every video I've seen posted today has been like that, and I'm not sure why. When I clicked on your link there, the black video panel showed up, but the video didn't start. Refreshing gave me the error message.

same here.

Same problems as stated above, btw i finally got it to work with the moonshell DLDI. Half of my songs crash the app or skip constantly. Nice work regardless.

Its as if its working, but perminately muted.
(yes, its patched)

Also, every feature on the pod gives a 404 except the music. (even the settings page). Is this meant to happen? (not made/yet), or is it just another error of mine.

You're probably using the wrong version. Get the latest version here: http://www.cecm.usp.br/~lucas/lmp-ng/.

Nope.
Its got worse in fact.
Downloaded the pre-compiled nds from the link, following results:

Moonshell boot ~ stuck on "Starting..." (waited about 3 mins)

DSOrganiser Boot ~ quite slow before even the "starting.." message, and when the starting message comes up its corrupted. (noise at the left and right, and stripply lines at the bottom...all on the top screen, bottom is fine). (same corruption each time)

DSOrganiser Boot Alternative ~ err..dunno what happens, DSOrganiser just restarts.

Im patching it for my GBAMP with the Patching script by PsychoWood

Try holding START when starting the program and copy the output here.

Try formatting your card, copying everything back and try again. If you don't want to do that, or if that doesn't work, start holding A and B, but it will disable ID3 tags.

I tried tracking this bug, but it's probably not in my code. I think its a problem in libid3tag, libfat or devkitARM, but I'm not sure :-/

LMP-ng: http://www.cecm.usp.br/~lucas/lmp-ng/

yup, disabling the ID3 tags worked :)

I didnt reformat, but I did try it on another card, and got the same problem.
Personaly, I can live without the tags.

"Shuffle songs" also seemed to crash it

Just released another version. http://www.cecm.usp.br/~lucas/lmp-ng/.

This is mainly a bugfix release. I've fixed most bugs reported here (every one I could reproduce). MP3 playback should be much better now.

I've changed the default to NOT read ID3 tags. There's some problems in the code that may cause instability. If you really want that feature, you can start the program holding A and it will be enabled, but in case you run into problems, just try disabling ID3.

One new feature, new seekbar (just test to see). Now the default is to change volume on NowPlaying screen, so you have to press WHEEL_CENTER or RIGHT to get to the seekbar.

Please, test and report any regressions. If your bug is still not fixed, please post again with detailed information on how to reproduce.

It's not possible to implement file attributes, because libfat doesn't export them, and I don't want to keep patches outside my tree. To solve the problem with moonshell STARTUP.MP3/SHUTDOWN.MP3 the moonshl folder is now ignored, so, don't put your MP3 files there.

New version still the same to me, still have graphical corruption, and my always the same mp3 wich worked on my first tested build either alpha 1 or 2, not sure, continues to not play properly, it has stopped playing properly since alpha3. It's a 192kb mp3. I'm not sure if it is VBR though!

How are you getting graphical corruption? How to reproduce? Do you have ID3 tags enabled or disabled?

What happens when you try to play this mp3? Freezes? Plays incorrectly?

The sound is still bad as in the video? Are you playing very high bitrate MP3 (320kbps and greater)? Have you tried formatting the card?

Can you try this build:

http://www.cecm.usp.br/~lucas/lmp-ng/lmp-ng-devel.zip

and test the results? I've increased the buffers and did some optimizations.

Hello, I would have a problem with the DS-Linker card, I have tried all your versions but no one works.
I have also tried to use DLDI but without success.
Excuses for my English am Italian.

The newest version is alot faster. :D
No Problems here on a Supercard SD
But i do have one little request, that when you Rewind/foward the song, that you put the time of the song like in a real ipod.

I've tried holding A and B to disable still the same problem!
I'm using a DS-X patched with the latest DLDI.

The Graphical corruption has happened in every version so far, and is only on 1st 3rd ofthe top screen, some garbled lines and battery icon duplication.

The MP3 does play, but sounds like if it was doing fast forward!

I'll do a video to show these off, after I format my card just to make sure!

I've just uploaded RC2 version. I hope this is the last RC. Download link: http://www.cecm.usp.br/~lucas/lmp-ng/.

Some small bugs fixed, some minor tweaks and optimizations. I've played for several hours, with no problems, tested mp3, ogg, flac and all were fine. Tested on R4 (dldi) and M3 SD (no dldi).

I'm also thinking of the new features for the next version, so if you want to suggest anything, now is the time. Please, for this next version, just small features, but features that may be useful. No video or streaming support yet.

Did RC1 worked for you? Strange, I'm using right now on a R4 and it's working fine. If you boot holding start, what do you get?

Cant wait for the Album, Artist, etc. sort
and the Skinable feature would be awesome.

P.S Only difference in RC2 i see from RC1 is that glitch where the forward/rewind bar doesn't show up when you click left or menu.

EDIT: Okay somthing just happened, when i load it its freezing. I didn't delete any Files for that, only thing i did was play Yugioh Gx and take a save out. I put it back and its still donig the same thing.
Note: this is happening in BETA and RC2 for me
Note 2: This is my first problem with LMP-ng

EDIT2: Nevermind i think it was the DSOraganize 2.5 Directory files.

sorry, didn't try RC1..but i did try the beta. worked fine.

holding start while booting still freezes. but on the album/artist tag see both as "NULL"
maybe it has something to do with tagged mp3's? i'll try a non tagged mp3 in a bit
Update: still freezes on nontagged mp3's. its a 192k mp3 if that matters

It should show NULL as artist/album, this is normal. When you start holding START, the frame counter in the upper right corner is freezed too?

This verison works fine on my R4, but the RC2 version does not and the RC 2 just locks up. I have patched both using the dldi thing.

Other testing RC2 lockup on m3 SD perfect, but the above file works fine :).

I'll update with a RC3 then... I just forgot to initialize a variable, that's why it's locking randomly at startup.

This MP3 player homebrew is really good. But it doesn't work on my DS-Xtreme 1.10.

There is some graphics corruption in the top screen and my MP3 is played for +- 3 seconds then it "crashs" and the player plays the MP3 at the start of the MP3.

Then the player plays again those 3 seconds of MP3 then it recrashs etc ...

I've tried DLDI patch with the DS-X driver but it doesn't change anything

You're the second one to report these bugs with DS-X. Which DLDI patch are you using? I saw chishm saying on another thread that the one in DS-X site have some problems, you should use the one on his site.

I'm using the DLDI patch tool v1.23. ( Dynamically Linked Disk Interface patch tool v1.23 by Michael Chisholm (Chishm) )

I found this patcher here :

http://chishm.drunkencoders.com/DLDI/index.html

I've tried this patch with some homebrews like Moonshell and it worked :/

Thanks for your help and for your work ! ;)

Really thanks for your bug report!! It helped me track another bug that may cause graphical corruption.

Please, try this version here and let me know if it fixes your problem: http://www.cecm.usp.br/~lucas/lmp-ng/lmp-ng-devel.zip.

just tried out rc3, and music playback didn't work very well..
half a second of the song would sound normal and the next half second would sound like fast forward..
message was always: "recoverable frame level error (lost synchronization)"

SC SD DLDI..

but please keep it up :) the interface looks so much better than moonshell or dsorganize..

Now, the songs see perfect :D :D. Thx a lot.

Well, I want to know something: when I'm playing a song, when I in the menu searching songs, it doesn't go equal than when I'm not playing a song. I supose that this is not a bug, and it is a problem with the nds, right lucas?

Really, now it is more than perfect for playing songs, thank you a lot ;-)

d4rkb1t

What do you mean? It responds slower?

I'm a PSP hacker now, but I still <3 DS.

That's probably what he means. When a song is playing, pressing down repeatedly does not scroll down at the same rate as when you are not playing a song. I think the scrollwheel scrolling was also affected, but I forgot by how much.

Well, looks like its much more stable now, with less bug reports, so I'm releasing version 1.0 now. Download: http://www.cecm.usp.br/~lucas/lmp-ng/.

Enjoy. I'll start working on new features now.

I was just going to edit my first post. Anyway, I tried with a DLDI driver for slower SD cards, and it plays MP3 fine. I only have Mp3.
Anyways, the top screen flickers between my EZ4 top screen and the media player top screen rapidly! The driver has nothing to do with this. Maybe you should try to clear the screen on the startup? Is it to any good?
EDIT: The border flickers.

No, but it is different. When I cycle through selections it kinda flashes, but it is flickering still when doing nothing, gah, it's difficult to explain. Video;
http://www.sendspace.com/file/n0czde

The screen flickers very fast when it is idle, and is clearly seen by human eye but my camera didn't catch it.

No, but it is different. When I cycle through selections it kinda flashes, but it is flickering still when doing nothing, gah, it's difficult to explain. Video;
http://www.sendspace.com/file/n0czde

The screen flickers very fast when it is idle, and is clearly seen by human eye but my camera didn't catch it.

Thanks for the video, I wasn't sure what was happening. Please, try this now:
http://www.cecm.usp.br/~lucas/lmp-ng-devel.zip.

Object not found!

The requested URL was not found on this server.

oops... sorry... here is the correct url: http://www.cecm.usp.br/~lucas/lmp-ng/lmp-ng-devel.zip

Thanks!
The flicker is history. ;)
What did you do?

Just as you said... I wasn't resetting the screen when initializing the video. Now I do :-) (in the first try I was just resetting the front buffer, but not the backbuffer, that's why it was different)

It's just a small bugfix with handling non-ASCII chars from RC3.

I uploaded 1.01 which fixes a bug with EZFlash.

But I promise I'll post detailed changelogs from now on ;-)

You can find my NDS homebrew projects here...

Just wondering, has ID3 support been removed from the latest version? It just shows the filename, even when I hold down A while starting the homebrew.

No big deal though =P Ruddy fantastic homebrew though, it's replaced Monshell on my DS as far as audio playing goes... :D

Yeah, removed from version 1.0... It wasn't stable enough... But! I've already fixed that, rewrote the metadata code, now it also supports ogg and flac metadata. I'm writing skin support now, so you can expect a alpha preview of the next version very soon.

MP3 playing still doesn't work with my SC SD.. :(

Hello ! Thanks for the lastest releases, it's now very stable for my supercard SD...

Could you add in the archive of the sourcecode the makefiles? (.BAT or .pnproj)

I can't compile my own builds :'(

And about the skins.. For the animated progress bar, which format will we have to use ? animated gif ?

Cheers,

Darkgilson

"Makefile" is the makefile ;D

Some people don't know how to drop to a command prompt, cd to the proper folder, and type make.

Already answered, but in order to compile you'll need to port some other libraries: zlib (easy), libid3tag (relatively easy, just two or three lines patch), libmad (easy), tremor (easy, but there's two fixes already commented in this thread), and libFLAC (this one is not so easy, it depends on some things unavailable in devkitARM like ntohl, utime, chown, chmod, so you have to write some stubs / replacements).

The Makefile is full of '/' for dirs, don't know if it works in windows, but should work, at least with cygwin.

You'll also need devkitARM r20 and latest libnds / libfat.

If you're having trouble compiling, PM me and I'll try to help.

I've already finished the skin code, but the only "animation" so far available in the progressbar is scrolling to the left. Now I need to do some boring stuff like creating a parser for reading a config file and loading the skin dinamically (I'll probably use a zip file for the skin, with a config and 16 bits A1R5G5B5 bitmaps inside).

I have an M3 Lite and I wanted to say that I absolutely LOVE this. Everything worked perfectly for me and I was really impressed. Keep up the good work.

Can you provide the patches against the source trees of these libraries? If you're using libmad, then your program is GPL, and you have to provide either these patches (plus the original source distributions) or pre-patched source trees.

It does. MSYS handles translation of, say, /e/develop/wallkick/src/lj.c to E:\develop\wallkick\src\lj.c.

Thks for the new version. Keep up the great work!

Although it still doesn't work properly on my DS-X.
Still has graphical corruption, and sound still skips and creacks.

This time I found it better to send a small video ^^, Much easier than having me explaining!
http://www.youtube.com/watch?v=KggG7bnuxGM

The file is a 160Kbit MP3, not much better than the 192K ones I tried earlier. Apparently it's a CBR, although I'm not sure, I'm not really sure how to know, usually in the windows explorer tooltips if they vary in bitrate it's because they're VBR. The entire album is 160 so it should be CBR.

Thanks Lucas for the reply ! =D
I aprreciate you are very close to the community :-)

In fact I wanted to translate the text shown on the display (music, random etc...) into French.

Do you think it's possible to modifiy those caption with an external file ?
Like Beup for an example...

Regards,

Darkgilson

I've just uploaded version 2 alpha. There's a LOT of new code, so be prepared for some new bugs.

The most noticeable chages are:

- Skin support
- Metadata support (ID3, VORBIS_COMMENT)

I've provided two skins as examples for thoso who want to create their own skins. The bitmaps MUST BE 16 bit ARGB (A1R5G5B5) (I used The Gimp to create these skins). You also need a skin.conf file which configures some basic features of the skins (look at the provided examples and play a little, it should be self-explanatory). The files must be zipped and put in /lmp-ng/skins directory into the card, the program will search for them and you can load them dinamically through the menu.

If you create some skins, please send them to me (along with some screenshots) so I can put them on my homepage.

@tepples: Sure, heres the patches: http://www.cecm.usp.br/~lucas/lmp-ng/patches.tar.gz. I've updated the page with some info on how to compile the source.

@alfatreze: Please, try this latest alpha version and see if it fixes the problems. There's a big rewrite in the screen code.

@darkgilson: I'll try to add support for localization in the next version.

This version still doesn't work on my DS-Xtreme :/

Now I can't see anything, just some bugged text on black background in the top screen and blue screen in the back screen :/

The playback is a bit better : Now it can play 3 seconds, then a bug, then 1.5sec, then a bug, then another 2 sec (total : can play 6.5/30 seconds \ o /)

Have you copied at least the default (default.zip) skin to /lmp-ng/skins ?

Of course !

If you're getting a black screen, then it means that the skin file could not be opened / unpacked successfully. Unfortunately, it's almost impossible for me to debug this without access to DS-X hardware, so it probably won't work unless some other developer with access to DS-X can take a look or if someone can tell me the reason it's not reading the files correctly. Sorry :-(

I think I found a bug that might be related to people reporting skipping in songs. Just uploaded version 1.02, please try and report (especially DS-X users). This is just a bugfix-release.

I have to say the media player is coming along nicely. I look forward to new features / capabilities.
I still have not switched over to it as my primary player because of one small issue. While at work I leave my DS on my desk and just listen to my music collection through the DS. I would prefer to be able to reach over and tap a single button to pause the player and/or advance to the next song. Therefore, if you are still taking requests, it would be great if there is a third option to the L/R button function. It would be nice to allow those that choose to hit the L to pause and the R to advance.

Thanks to Lick for getting the concept off the ground and Lucas for following through! Had trouble initially on my R4DS but after DLDI patching it runs great!

If you're still taking requests I have a BIG one. How about playlist support for m3u and wpl?

I use windows media player on my desktop. It's free and I've yet to find a better tool for organizing and tagging my vast collection of MP3s and it plays nicely with windows mobile on my wife's cell phone. I use the sync feature to get the MP3s onto the microsd and would like to preserve the directory and playlist structure on my desktop. I find that I cannot seamlessly sync files + playlists on most flash memory based MP3 players. It would be nice if LMP did this.

Yes, this is even more important for those who have their DS connected to their car stereo. With this setup in Moonshell I can reach over and choose songs without ever looking even in the general direction of the DS.

M3U playlists are supported, I don't know what is this wpl playlist, but if it's simple enough (like m3u), I can probably add support for it too. Just send me a description of the format and I'll try to implement.

It would be nice if you can hide the file name extensions (.mp3, etc.) when displaying the song names.
