Summary of the bug: Trying to transcode a FLV file with speex audio (no
video track) into a wav or mp3. This is generated by Flash Media Server
4.5. It works fine using ffmpeg version N-42616-g204c4e9 with gcc 4.4.3 on
Ubuntu 10.04 LTS. I am trying to transcode on my dev machine which is OS X
Mountain Lion 10.8, using HEAD ffmpeg.
How to reproduce:
