Here is the bug on cinelerra for ffmpeg support
http://bugs.cinelerra.org/show_bug.cgi?id=390

Gentoo have also a patch but it is reported not to work well
http://sources.gentoo.org/viewcvs.py/gentoo-x86/media-video/cinelerra-cvs/files/
There is also another patch I will consider to add if still needed...
