doesnt make too much sense to have it moved around.

At the moment I have a task scheduling framework that schedules tasks to
idle threads. The ffmpeg encoding/decoding is thus sliced into tasks and
those get picked up by idle threads. I just wanted to know if I need to
have a deeper look into my code or if accessing AVFormatContext from
different threads (without simultaneous access) is not okay.

I have a working version that uses only one thread created manually outside
of the framework (thus it ensures that AVFormatContext will always be
accessed from the same exact thread).
