[FFmpeg-devel] [PATCH] MP3 conformance in FATE

[Vitor Sessak]

$subj. I didn't succeeded in making all the tests pass. The output looks 
like:

The attached patch tests all the files that decode close enough to the 
reference encoder to be conforming. Also, the FFmpeg mp3 decoder output 
a little more data than the reference decoder, so I needed to pass a 
hackish "-fs" parameter to the command line.

Any suggestion to avoid the "-fs" hack or making the other tests pass 
are welcome. For anyone wanting to try, the files are in
