Michael Niedermayer	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 Originally committed as revision 2772 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Michael Niedermayer	8a36717afc	rv10/obmc fixes Originally committed as revision 2768 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Michael Niedermayer	99683a3077	2 byte shorter userdata for mpeg4 in the past it was startcode,string,00,7F,startcode now it is startcode,string,stratcode both are mpeg4 compliant, as according to the standard the userdata lasts until the next 00 00 01 (startcode prefix) but some very primitive decoders which simply skip until the first 00 byte and then expect the next valid startcode might fail with the old variant, just a theory though (didnt test if quicktime can decode it now) Originally committed as revision 2767 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago

Michael Niedermayer	65a24d0b39	optimization & bugfix extracted from the 4k line diff between ffmpeg 0.4.7 and http://www.alicestreet.com/ffh263.html the other parts of the diff where 1. spelling fixes (rejected as only a small part of it could be applied automatically) 2. cosmetics (reindention, function reordering, var renaming, ...) with bugs (rejected) 3. rtp related stuff (rejetced as it breaks several codecs) 4. some changes to the intra/inter decission & scene change detection (quality tests needed first) Originally committed as revision 2721 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
