Hi Rene,

Perhaps. But SDL_ffmpeg is a separate project, another dependency. FFmpeg is
much more likely to be on someone's system. SDL_ffmpeg also uses a
completely different build system, complicating the process of using it
within pygame. I'm having trouble getting it built against ffmpeg 0.5.0 and
I can't find any info or instructions on building it. If I'm having trouble,
it'll also be difficult for others. Its just not ready for wide-scale usage,
in my personal view.

Like I said, I am definitely leaning towards just using ffmpeg directly. It
also means I have greater control over whats going on, and don't have to try
to fiddle and be stopped by the limitations of sdl_ffmpeg.
