Hi,
Please read this post before continuing. It's about current FFMPEG rate control status for MPEG-1/2 encoding:
http://dvdripping-guid.berlios.de/forum/viewtopic.php?p=652#652
"It is not that xvid rate control is better (it completly lacks real min/max bitrate control), but it is simpler than libavcodec."
"FFmpeg ratecontrol is very powerfull but quite hard to follow.
Xvid one is pretty simple and easy to interface with other codecs."
These are part of the posts where an idea of adapting XVID rate control for use with something else than MPEG-4 codecs is growing.
I don't really know about that lack of max/min bitrate control part, but I do think that non-MPEG4 codecs could benefit from XVID's rate control experience :)
Immediate advantages would be backing up DVD9-to-DVD5 in Linux four times faster - FFMPEG is four times faster than mjpegtools, but lack rate control for the moment.
Rududu and other new codecs are also working on this subject a lot and could really benefit from such a project.
I'd like to know if a somewhat codec-independant rate control library based on XVID's is considered feasible :)
Best regards,
Bilu
