[FFmpeg-devel] a64 encoder

So after getting the hint on the mplayer-dev list to better implement my
encoder things with ffmpeg to make it available to a broader range of
applications, i did so. Encoding works fine so far for a bunch of modes.
The muxer is yet kind of very simple by just adding two bytes header
information (what is so far the loading address for files on a commodore
64) I shall add information about the used mode, fps and so on as well 
to the header, but so far, the players i wrote for the c64 are still 
kind of experimental, and forgo on that header information anyway.

Attached you'll find the patch for review, if you find it worth being 
added to the repository, i'd be happy.

Future work will consist of adding also decoders and sound support, that
might basically be a kind of simple FFT that will be played back by
three sin-waves on the analogue chip of the c64. The output is low
quality, but bandwidth saving of course. However i am still 
experimenting on that.

Converted movie examples (some frames in a loop) can be provided with a 
displayer. They are all runable on c64 emus like vice for e.g.

Kindest regards,
