Michael Niedermayer	155ec6edf8	quad tree based motion compensation (currently only 16x16 & 8x8 OBMC blocks, but can be extended to other block sizes easily) different intra block coding (previous was just an ugly hack) 1.8% bitrate reduction -0.01PSNR (foreman@352x288 qscale=8) 1.5% bitrate reduction +0.05PSNR (foreman@352x288 qscale=1) Originally committed as revision 3416 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago

Michael Niedermayer	f20f8a8b0b	support reusing mb types and field select values of the source file, but use motion vectors just as additional predictors minor cleanup segfault fix Originally committed as revision 3060 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
