Benjamin,

I'm really just trying to find out if we need to start a new bug for a problem
with Audacity apparently recognising SVN FFmpeg but then giving an error
dialogue in the GUI when importing FFmpeg files. That is, is the problem
specific to latest FFmpeg builds, but doesn't occur with a build from a bit
earlier like the current Ubuntu FFmpeg? Or is it to do with how Audaoity has
been configured?

Three people on the Forum including me, and a couple of others I know of get
"av_open_input_file()failed" in the log when the import failure happens with
SVN FFmpeg. Steve gets "Failed to retrieve file times for '/nyquist worker/'
(error 2: No such file or directory), Error: can't open file '/nyquist
worker/'" when using SVN FFmpeg. Steve's issue could possibly be some conflict
with Nyquist Workbench. Steve's and my problems go away when using the Ubuntu
FFmpeg (except for the WMA and AAC export problem).

So it would be great if you (who knows more what you are doing :=) could
install SVN FFmpeg and compile Audacity with USE_SYSTEM_FFMPEG.

Steve and I were compiling with default ./configure and the configure output
was showing "using SYSTEM libraries" for FFmpeg. I can't find out what the
other four people were doing exactly.

If local libraries are used instead of system, is that for the case where you
link to a library version you have not installed? If so, how do you configure
Audacity to the correct path for the local library?
