[FFmpeg-devel] segfaults: Internal buffer inconsistency. flushbits <> ResvSizebit reservoir error

[Artur Bodera]

Hi!

When transcoding another MP4 I've just received: "Internal buffer
inconsistency. flushbits <> ResvSizebit reservoir error:". FFmpeg is
throwing french at me? :-)

It happens on this particular mp4 file (encoded with handbrake, plain
default settings).

Any ideas what could be the cause and how to work around it?
