Comment 15 for bug 602934

The current situation seems thus for most people. If you self-compile FFmpeg
greater than 0.5 and point 1.3.13 to it, Audacity either:

* does not recognise FFmpeg
* recognises FFmpeg with errors which may lead to repeatable segfaults
* appears to recognise FFmpeg but can't recognise valid files on import

On Ubuntu 10.10 if I point 1.3.13 (compiled with default ./configure that
produces "use ffmpeg=local") to the Synaptic-installed Ubuntu FFmpeg package,
1.3.13 seems to fully recognise FFmpeg and works properly without crashes.
(Steve does get intermittent crashes in that scenario importing WMA or AC3
files which had been exported by 1.3.12).

I just confirmed my results by reinstalling Ubuntu 10.10, and rebuilding
Audacity with default ./configure against Nikola's av-match-ext patch
(http://forum.audacityteam.org/download/file.php?id=2253). If I then recompile
Audacity with default ./configure against the attached bug 176 patch, I'm back
to Audacity not recognising FFmpeg with the "undefined symbol:match_ext" error.
