Hi guys,

I've found an example video_decode_example at avcodec.c (mine is an old
version so this might have been moved to another place)

in which the codeccontext is initialized with avcodec_alloc_context3 so no
avformat context is needed.

That way I can call av_decode_frame with my own demuxer.
