1. Ensure you use recent git master HEAD of ffmpeg.
2. Provide minimized, but compiling source code that reproduces your
problem, together with media files that are problematic for your app.
3. Provide full uncut output of ffmpeg utility which processes
problematic files fine. With -loglevel debug.

Large pastes are better to not inline, but post on some pastebin etc.
