 null pointer segfaults
 dont print redundant spam

(f)printf() is disallowed in libavcodec, compilation will fail now if its used, except that codecs which where added after the printf->av_log change which did ignore av_log() and used prinf are now silent and wont print anything, they should be changed to use av_log, i could do that, but its better if the orginal developer decides which AV_LOG level each message should get

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

ppc chroma mess workaround (real bug is that the motion compensation code assumes that 2*uvlinesize == linesize and fixing this would mean a slowdown)

use lagrange multipler instead of qp for ratecontrol, this may break some things, tell me ASAP if u notice anything broken
quality which was 1..31 float is now a 1..FF_LAMBDA_MAX int, and FF_QP2LAMBDA * qp can be used to convert to the new range
