ffmpeg in 10.3/unstable will not decode AC3 audio. ffmpeg's libavcodec needs to dlopen liba52, but the path passed to dlopen is hardcoded with the .so extension, which does not match the .dylib extension that the library is installed with.
The same problem is present in the dlopen of libfaad elsewhere in libavcodec.
Adding the following to PatchScript in ffmpeg.info takes care of both of these problems. They should logically be added near the other .so-to-.dylib patches.

### Still more fixes for dylib
perl -pi -e 's,liba52.so.0,%p/lib/liba52.0.dylib,g' libavcodec/a52dec.c
perl -pi -e 's,libfaad.so.0,%p/lib/libfaad.0.dylib,g' libavcodec/faad.c

Patch for ffmpeg.info follows. For two lines, I don't know why, but some people really just prefer patch files.

This bug is accounted for and patched in ffmpeg 0.4.6-11 in 10.2-gcc3/unstable, apparently the patch never made the leap to the new tree.
