Details

Description:

Audacity up to version 1.3.7 is compatible with ffmpeg up to 0.5.

Ffmpeg changed its API after 0.5.

Audacity versions later than 1.3.7 (ie 1.3.8, 1.3.9 etc.) cannot use ffmpeg 0.5 (that is the version currently in extra) to import many audio file types (ie MP3, AC3, AAC etc.). These version need an ffmpeg version (svn) later than 0.5.

Proposed solution:

Build and package in extra a newer than 0.5 version (svn) of ffmpeg.
This task depends upon

I did not try import, but I was trying to export to m4a. I believe this is the same error. Debug log shows the following :

12:27:06 AM: Trying to load from system paths. File name is libavformat.so.52
12:27:06 AM: Loading avformat from libavformat.so.52
12:27:06 AM: Importing symbols...

12:27:06 AM: Failed to load symbol av_free_packet

ffmpeg-svn is also currently broken, or atleast the current svn tip is broken. It fails to compile, effectively meaning no audacity+ffmpeg work can be done as of now.

Shifting from x264 to x264-git, enables ffmpeg-svn/ffmpeg-mt-git to compile, which is solving the problem for now.

forgot to mention, the svn/git packages only work if compiled with --disable-encoder=aac

FYI, we're planning to update soon the x264 and ffmpeg in the repo. When it'll be done this bug will be fixed.

This is good news.

It works with the new ffmpeg in testing.

Correct.

So when the new ffmpeg moves officially into extra, this bug can be formally closed.
