Comment (by pulkomandy):
So, I got ffmpeg 0.11.5 to compile and run after a number of hacks. There
are some good news: it seems it doesn't break video and audio decoding. So
we could actually update to it (#8856 somehow isn't a problem anymore).
But there are also some bad news: the vorbis encoding still fails.
However, the error is more obvious this time. What happens is the
libvorbis encoder in ffmpeg only can accept floating-point format as an
input. I guess most ffmpeg encoders are designed the same. But our media
plug-in doesn't propagate this information, and MediaConvert tries to feed
integers to the encoder instead. ffmpeg added an explicit check for this
in version 0.11, so they error cleanly, but the error isn't handled
properly by our plugin and in the end MediaConvert crashes.
