Any progress on this?
FFmpeg is so close to supporting my entire audio library now.
Thanks!

comment:5 Changed 3 years ago by DJX

Still very interested in seeing this come to fruition.
Has there been any development on this?

comment:7 Changed 3 years ago by llogan

  • Keywords bounty added

comment:8 Changed 3 years ago by DJX

Who ever fixes this can collect on both of these bounties:
https://www.bountysource.com/issues/6557774-wmalossless-fix-24bit-support
https://www.bountysource.com/issues/1414845-wmalossless-support-24bit-depth

However, the bounty should be dependent on this issue being fixed as well:
https://trac.ffmpeg.org/ticket/4714

comment:9 Changed 3 years ago by DJX

Just checking in on this.
So many projects use FFmpeg, this would solve a major hurdle for me.

comment:10 Changed 3 years ago by DJX

After 12 seconds of play in ffplay.exe noises appear.
MPC-HC with WMAudio Decoder DMO plays normally.
foobar2000 also plays normally.

File encoded from mp3 in foobar2000+WMAEncode.exe (https://hydrogenaud.io/index.php/topic,90519.0.html)
I chose the 16-bit, but encoder made a 24-bit. I think this is due to the fact that the original file was a strong clipping.

It looks like ffmpeg's wmalossless decoder (24bit 44khz mode) has problems with high amplitudes:

org.wma - file encoded from org.wav
org_0_99.wma - file encoded from org_0_99.wav

ffmpeg -i org.wav -af "volume=0.99" org_0_99.wav

What's also interesting: org.wma size vs org_0_99.wma size.

It decodes correctly with original MS codec. I don't think that there is any other open source implementation.

I know that already, looking for executable/dll.

comment:17 Changed 3 years ago by DJX

Here is the last version of Windows Media Encoder:
https://www.djxmmx.net/ffmpeg/4134/
Two EXEs for installation.
Alternatively, I copied the installation directory from the 64-bit version so you can examine the DLLs or EXEs it installs.

M$ discontinued the Windows Media Encoder so that's why I linked to it from a private server.

Can I get decoded output too, in 24bit pcm?
The thing ami_stuff posted is resampled thus useless to compare bit exactness.

comment:22 Changed 3 years ago by DJX

Sure, check the WAV files I just put in there.

comment:23 Changed 3 years ago by richardpl

What you used to decode those?
FFmpeg decoder with my patch decodes same thing as wmal2pcm and 09 sample have noise at end but your decoded output doesnt.

Doesn't same happens with 16bit files?

comment:32 Changed 3 years ago by ami_stuff

for 16bit there is only one encoding mode (44khz, 2 channels)

Right, WMA Lossless will only do multichannel at 24-bit.

It would be very nice if you guys could isolate that audio which is causing problems and encode only it, so its length is very short. This would speedup debugging tremendously.

Funny, looks like 16bit decoding is buggy too.

This was unrelated bug that I just fixed. So still need that sample(s).

Actually the only remaining issue AFAIK is not bitexactness of "09 - Walk On By.wma" with latest reference decoder.
Our decoder decodes same output as WMAL2PCM.exe program.

I think noises in 24bit decoding are finally fixed.

If you happen to know how to isolate this with ffmpeg

ffmpeg -i t96.wav -ss xx -t xx out.wav

then I can encode only this fragment of the audio.
