Detailed Description

Internals of the FFmpeg reader.

This code is supposed to seek to the nearest previous key frame if needed, then to step through the frames up to the required frame. Due to some unpredictable behaviour in the key frames reporting and their time tagging : when a problem is detected, the key frame control structure is filled with only the first sequence frame. It is much slower, but (knock on wood) works.
