mpeg4 b-frame enoding support removed old, out-commented ratecontrol reuse motion compensation code between encoding & decoding prefix newly added global functions with ff_ to reduce namespace polution b-frame ME (unfinished, but working) added some comments to mpegvideo.h do MC on encoding only once if possible bugs? ;) Originally committed as revision 403 to svn://svn.ffmpeg.org/ffmpeg/trunk
