Michael Niedermayer	b6335c9f5b	ff_copy_bits() optimization Originally committed as revision 2777 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Michael Niedermayer	a734250db6	activate the memcpy special case for the byte aligned case in ff_copy_bits(), wasnt working before because of a incorrectly used pbBufPtr() Originally committed as revision 2775 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Michael Niedermayer	cfbd16df75	replace a few pbBufPtr() by put_bits_count(), one of them was actually wrong Originally committed as revision 2774 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Michael Niedermayer	80ee9fc0e3	simplify MV availability check / dont use below last row MV which is always zero Originally committed as revision 2773 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
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	7984082a08	ppc chroma mess workaround (real bug is that the motion compensation code assumes that 2*uvlinesize == linesize and fixing this would mean a slowdown) Originally committed as revision 2771 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Roman Shaposhnik	826ca10408	* gotta setup coded_frame for encoding. avcodec.h says that for decoding lavc is supposed to set it up as well and I don't think I see any reason not to. Originally committed as revision 2769 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

Tinic Uro	747a0554ea	- made --extra-cflags option work on darwin - allow INTER4V macroblocks for FLV1 codec - fixed issue in flv file format saving 8 mp3 frames per packet instead of 1 - fixed crasher in flv file format involving mp3 buffer handling - added FLV1 codec support for swf file format (FlashPlayer6 or above required) and made it default - fixed broken mp3 support in swf file format patch by (Tinic Uro <turo at macromedia dot com>) cleanup by me Originally committed as revision 2756 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
