Ok; I tested the non-mmx version, and it is quite fast (about as fast as
x264 with mmx optimizations). Quality is not good, but I guess it can be
enhanced ;-)

Ok, I see the problem... Maybe having your code in ffmpeg's svn
repository (in a branch) will help with it.

Anyway, I think that creating troubles to you (such as having to resynch
with ffmpeg's svn more often than you would do, or to create and publish
patches too often) only for sharing your code with other people is not
I think it would be more reasonable to find a way to publish your work
in the simplest way for you, even without resynching it with latest
ffmpeg svn. Interested people can easily port it to the current svn of
ffmpeg (and contribute back to you this update-to-ffmpeg-svn patch), and
create patches for ffmpeg.

BTW, talking about the code... I see that support for the
CODEC_FLAG_GLOBAL_HEADER is not implemented yet. How can
./ffmpeg -i sourcevideo -vcodec ffh264 -vtag avc1 -an targetvideo.mp4
work? (Or am I missing something as usual?)
Anyway, if you are interested I can try to work on it and provide a
patch for supporting CODEC_FLAG_GLOBAL_HEADER in one week or two.

Copy this in your signature, if you think it is important:
                               N O    W A R ! ! !
