Last year, my patch got into FFmpeg repository, just now, after FFmpeg 0.12.2 marked as stable after 0.7.8, I saw my contribution (from FFmpeg manpage):


Unfortunately, I didn't carry on after I created x11grabr. The issue I has still remained and I didn't try to resolve it very hard. Since then nothing was done, it was sort of ceased of development. When I started x11grabr, I wished I could make it like XSplit on Linux. Despite issues, my computer couldn't handle much encoding let along I don't really have anything interesting for live broadcasting.

If you are interested, please send me an email, maybe we can team up.
