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)

9c3d33d67f multithreaded/SMP motion estimation 
multithreaded/SMP encoding for MPEG1/MPEG2/MPEG4/H263
all pthread specific code is in pthread.c
to try it, run configure --enable-pthreads and ffmpeg ... -threads <num>
the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c
