LOL. I was just referring to doubts regarding the documentation. OTOH,
some details are not or cannot be explained, so when a user poses a
complicated "how can this be achieved" question, I just try my best,
making use of experience.

Unfortunately, introductions and explanations are more to be found in
the Wiki than in the formal docs.

This needs to be checked - I'm too lazy to analyze the source, and
others know this functionality better by heart - but for any doc
shortcomings you are sure about, patches are truly welcome. I have
submitted some small stuff to ffmpeg-devel, and it was mostly accepted.

Developers are more keen on getting code done than on pimping existing
documentation, so volunteers are also welcome. I pretty much agree with
you that there are shortcomings in some fields.
