Audacity cannot locate the libraries for ffmpeg in version 1.3.8. Reproducible: Always Steps to Reproduce: 1. Load Audacity 1.3.8 2. Attempt to use something requiring ffmpeg, witness error message 3. Check location for you ffmpeg libraries, and even when pointing to it doesn't locate them This is apparently an error that has been fixed in 1.3.9
Not related to gnome in anyway, please don't touch fields you don't know the effets of and let bug-wranglers do their job. Plus you really need to add emerge --info and a log showing your problem as bugzilla says.

Please describe the problem a bit more and explain what has been fixed in 1.3.9 or point to a discussion about it.
I had the same problem (ffmpeg library not detected) with audacity-1.3.8 and ffmpeg-0.5-r1. On the Audacity FAQs [1] I found out that: "For Audacity 1.3.8 or 1.3.9 on Linux, a FFmpeg library or package later than 0.5 is required." confirmed also on the release notes [2] and [3] (scroll to the end of both pages). I upgraded to ffmpeg-0.5_p19928 but the issue was still there; later, I recompiled audacity-1.3.8 and solved the problem. However, I do not know if there are other upgrade paths that restore this functionality.

I ran into this problem as well. Upgraded Audacity to 1.3.9. Audacity complained that it couldn't find ffmpeg, even when I explicitly told it where it was. recompiled ffmpeg followed by Audacity. That didn't help. Upgraded to ffmpeg-0.5_p20373, recompiled Audacity, and it worked. Audacity 1.3.9 does not work with ffmpeg-0.5-r1. emerge --info Portage 2.2_rc52 (default/linux/x86/10.0/desktop, gcc-4.1.2, glibc-2.9_p20081201-r2, 2.6.30-tuxonice-r5 i686)

I have basically the same bug with audacity 1.3.11 (and ffmpeg-0.5_p21602) on an amd64 system. I'm working on a project consisting of a second of silence. At first it complains it cannot find ffmpeg. When using the configuration item to point audacity to the library it will find it. Then when I try to actually export the project as aac/m4a it will crash after the metadata settings part. ffmpeg is built with both the faac and faad use flags.
The same problem here with Audacity-1.3.12 and FFMpeg-0.6 on amd64 machine. Audacity cannot locate the 'libavformat.so.52' even when I point the path explicitly to this library.
I'm seeing the same issue as comment #6, except with audacity 1.3.8 (but also ffmpeg-0.6). According to <http://manual.audacityteam.org/index.php?title=FAQ:Installation_and_Plug-Ins#installffmpeg>: Any FFmpeg libraries or packages built in 2010 may not be recognised by Audacity (Help > Show Log will list an error "undefined symbol: match_ext"). Workaround: Re-compile Audacity and change all instances of "match_ext" in ../src/FFmpeg.h and ../src/FFmpeg.cpp to "av_match_ext". I do see the error message mentioned in "Help > Show Log": 03:22:14 PM: Loading avformat from libavformat.so.52 03:22:14 PM: Importing symbols... 03:22:14 PM: Error: /usr/lib/libavformat.so.52: undefined symbol: match_ext 03:22:14 PM: Failed to load symbol match_ext There is an ubuntu bug, <https://bugs.launchpad.net/ubuntu/+source/audacity/+bug/602934>, which includes a patch (in comment #2). Adding the patch to the ebuild for audacity 1.3.8 results in a working audacity---at least, I can import .wav files and I don't get the undefined symbol error.
I've added a patch to CVS that allows audacity to compile against any version of ffmpeg currently in the tree.
