This ffmpeg version has a big api change. I'll attach the patch; note that I have *not* upstreamed it as I don't know how you handle your relations with upstream. If you want me to do it, please let me know. This bug will serve me to track the unmasking of ffmpeg from another bug, so please don't close it until it's really ok.
Created attachment 168430 [details, diff] fix this should do it, use avcodec_decode_audio2 instead of the old one, setting the length to get the exact same thing as avcodec_decode_audio
