VLC unable to convert movie

Postby ajmas » 29 Dec 2007 19:09

I am wanting to slowly migrate all the movies I have to MPEG4 (AAC/H264), since currently I have a mishmash of different formats. From my experience VLC is not always capable of converting movies that is capable of playing back. In cases like that should I open a bug ticket?

Some examples:

Format: Quicktime movie (from camera) mp4v/ulaw
Result:

Code: Select all

main: thread 2690178912: mutex_lock failed at misc/variables.c:805 (22:Invalid argument) main: thread 2690178912: mutex_unlock failed at misc/variables.c:811 (22:Invalid argument) ffmpeg: cannot open encoder stream_out_transcode: cannot find encoder ((null)) stream_out_transcode: cannot create audio chain main: cannot create packetizer output (ulaw)
Format: WMV WMV3/wma2
Result:

Code: Select all

main: thread 2690178912: mutex_lock failed at misc/variables.c:805 (22:Invalid argument) main: thread 2690178912: mutex_unlock failed at misc/variables.c:811 (22:Invalid argument) ffmpeg: cannot open encoder stream_out_transcode: cannot find encoder ((null)) stream_out_transcode: cannot create audio chain main: cannot create packetizer output (ulaw) main: cannot add a new stream (unsupported while muxing to this format) main: cannot create packetizer output (wma2)
In fact often enough it is the sound that fails to be converted.

EDIT: using 0.8.6c

EDIT: Looks like ffmpeg SVN-r9102 seems to do a better job, so there version included with VLC is probably outdated. Any ideas when vlc will get the latest ffmpeg changes?
Providing logs, messages, configuration info (VLC, OS, Hardware) and a clear explanation of the issue always helps the problem solvers help you, even if they don't end up solving the issue. Just think what you would need if you were solving someone else's problem. Additional: Always looking for eager and capable MacOS X developers to join the VLC team - for more information see here.
