mpc files not playing anymore

[zdahAli]

Hello,
mpc files (musepack) used to work (on vlc 0.9.9a under OS X 10.4 and on vlc 0.9.4 under Ubuntu 8.10) and I can't play them anymore, I have the latest stable version of vlc (1.0.1) running on OS X Leopard.
waiting for your answers, ideas...
thank you

I have replaced the 1.0.1 version with the 0.9.1 version and it works ! it is definitely a problem with the > 1.0 versions.

[Jean-Baptiste Kempf]

Can you share the file?

[zdahAli]

I don't think it's legal, sorry ...
by the way, I have tested mpc files on vlc 1.0.1 under Debian 5.0 testing, and it works !

[apt]

I don't think it's legal, sorry ...

It is not illegal if you upload a short sample (~30 sec.)
Here you are a test one.
Cheers

[zdahAli]

Thanks for the sample !
The problem isn't solved with 1.0.2 version

[apt]

Well, Musepack support is broken in Windows compiles too, but it seems that development does not have enough time to fix it.

[Jean-Baptiste Kempf]

I can have a look. Send me more files.

Thank you. I've uploaded some test files to Mediafire, I guess they will be available for 7 days.

1. Musepack SV7 - plays fine
2. SV8 no tags - cannot be played
3. SV8 with tags - cannot be played
4. SV8 with tags and chapters - cannot be played

I've uploaded an SV8 file twice, with and without tags, because I've found out that some players crash with tagged SV8 files.
Please let me know if you have troubles downloading the files. Maybe I had to zip them before upload, I'll to that if you get broken files.

Edit:
I've uploaded a shorter SV8 with tags and chaps, no need to download the larger one.

[apt]

For the last two weeks the test files were downloaded once.
There is still hope

I've spent some time investigating this, and it looks like there are actually two
problems:

1. On MacOS X Intel, even SV7 files do not play. After inserting some msg_Dbg calls
into modules/demux/mpc.c, it looks like the binary of libmpcdec downloaded by the
package manager in extras/contrib is corrupted. It calls the functions ReaderRead and
ReaderSeek in the correct sequence and the functions return the right values, but
libmpcdec still decides that the file header is invalid. Rebuilding the library
(libmpcdec.5.0.2.dylib) from the official sources [1] fixes the problem for me.

2. At least on Windows and MacOS, VLC is built against libmpcdec-1.2.6, which does not
support SV8. However a new library that supports SV8 is available on the Musepack
homepage [2] and mpc.c already contains the necessary ifdef/configure magic to use it.

It looks like the VLC developers could kill two birds with one stone by updating their
prebuilt binaries of libmpcdec to the latest version.

Looks pretty easy, I don't understand how nobody fixed till now? The SV8 code is available since almost one year.

Probably because it wasn't high priority enough for most people to do it?

Or not enough knowledge of people which need it. Oh well...

[bobbertrailer]

I need to reinstall 0.9.1 in order to work.

[apt]

There is a small improvement in latest vlc-1.1.0-git-20100107-0002 for windows.
It already plays about a second from the beginning of a musepack SV8 file.
In the Codec Details window one can see "Codec: MUSEPACK8 Audio (MPCK)".
So, somebody is working on that, thanks guys.
Now the problem is how to play the rest (n-1) sec. of the file

Would it be possible to have an updated version built for the 1.0.4 release?

HI,

Anybody tried if 1.05 is playing mpc (musepack) files now on Mac OS X ?
I'm still running 0.99 and tired of trying every version since 1.00 just to see that mpc playback is missing before pulling back to good ol' 0.99.

thanks and have a good day

I do the same (trying every new version), but no luck so far. I'm on windows and my problem is the missing SV8 support. SV7 is working, though. What streaming version are your files? Just curious.

[cmagic]

Hi,

I am mainly using SV7 but I'm on a Mac and up to 0.99, VLC was the only way to play mpc files on the mac.
I tried VLC 1.0.5 in a Win XP Virtual machine and it plays SV7 nicely but it's cumbersome.

Maybe 1.0.6 will playback mpc on the mac ??

thanks for the feedback anyway

[zdahAli]

vlc 1.1.3 and still no support of the musepack codec ... the developers and the administrators of vlc don't seem aware of that, as they pretend to support it on the features page : http://www.videolan.org/vlc/features.php?cat=audio
hello ?!!! is there anybody out there ?

[cmagic]

Hi,

Yep, still no mpc support on VLC, Mac or PC.
What's the matter folks, have you completely forgotten musepack?

I am aware that musepack is not a mainstream format and used only by some obscure geeks. Based on that you might well have decided to drop support for mpc but then stop pretending that VLC can still play it.

BTW I'm still using VLC 0.99 on mac for mpc playing.

Cool, but I bet you have old mpc files (in SV7 format, which is considered obsolete).

[Jean-Baptiste Kempf]

Ok. Give me a link to 5 (at least 5, try to do a mix in different settings) mpc files and I'll fix it.

[apt]

I can make 5 (or more) different variants of one and the same small source file, compressed (and tagged) with different settings, I think this would be better than providing you 5 different files.
Maybe tonight, when I go home.
Thanks in advance, Man!
