Michael Niedermayer	44eb495128	divx5-gmc support q-pel mc support neither is totally bugfree yet though :( Originally committed as revision 320 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	73c8e5144a	gmc bitstream decoding support (the real motion compensation isnt implemnted yet) Originally committed as revision 318 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	cc9ba006ec	parsing more of the mpeg4 header & print some "not supported" stuff Originally committed as revision 317 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	d140623fc4	- H.263+ decoder support for Advanded INTRA Coding (buggy) Originally committed as revision 310 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	3232bc885d	* using static instead of extern Originally committed as revision 304 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	b4dbd87c04	- Minor changes on bitrate control Originally committed as revision 300 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	e03c341ef3	- More work on preliminary bit rate control, just to be able to get an average variance for picture's MBs so we can adjust qscale on the MB layer. Originally committed as revision 294 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	37fbfd0a91	- Now the ME is done for the entire picture when enconding, the DCT/Quantization is done after we have calculated all the MV of the picture. - This is the preamble for a better bit rate control. Originally committed as revision 293 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	81401c1fbc	- Fixes on RTP and GOB headers for H.263. - RTP callback system implemented for H.263/H.263+. - Bug fix on DC coefficients of H.263. - H.263 decoder now returns PTS on picture number. Originally committed as revision 292 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Arpi	80e103d04c	PATCH by Rik Snel <rsnel@cube.dyndns.org> this patch enhances the jpeg header writer. It can be asked to omit quantisation and huffman tables and it can write different horizontal and vertical sampling factors. (the last thing is useless for libavcodec itself (because libavcodec only handles YUV420P at ecoder level), but the values are initialized so that operation of libavcodec is not impaired) Originally committed as revision 290 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	2f349de286	(commit by michael) mmx & mmx2 quantizer c dct permutation bugfix dont copy input on intra only encodings if it can be avoided dont draw edges on intra only stuff Originally committed as revision 281 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	ae40484c1c	(commit by michael) bye bye weird al rounding bug ;) Originally committed as revision 268 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	bff6ecaa9c	AC table reset (memset) optimization - patch by Michael Niedermayer <michaelni@gmx.at> Originally committed as revision 251 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	644d98a4f2	- Preliminary RTP friendly mode for H.263. - GOB headers for H.263 coding on RTP mode. - Improved GOB header detection for H.263 decoder. Originally committed as revision 222 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	102d39088b	- Fixed a bug on H.263 MV prediction for MB on GOBs limits. - Now we can decode H.263v1 streams found on QT without problems. Originally committed as revision 214 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Nick Kurshev	a822a47983	fixed gcc-3.0.x compilation (by Michael Niedermayer) Originally committed as revision 211 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	544286b3d3	Moved some H.263+ variables to MpegEncContext to be thread-safe. Increase video_buffer on ffmpeg to avoid buffer overrun on big pictures. Originally committed as revision 114 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
Fabrice Bellard	58f26ba916	changed opendivx to mpeg4 Originally committed as revision 102 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
Fabrice Bellard	1a56543279	win32 fixes Originally committed as revision 84 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
Fabrice Bellard	3c054a1cdd	fixed scan protos Originally committed as revision 52 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
Arpi	4af7bcc185	MMX/MMXEXT iDCT support, using external functions currently defined in libmpeg2 Gives average 13-20% mpeg decoding speedup on x86 systems. Originally committed as revision 30 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
Fabrice Bellard	21af69f787	use block[] in structure to have it aligned on 8 bytes for mmx optimizations - dct_unquantize is always a function pointer - added specialized dct_unquantize_h263 Originally committed as revision 22 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
Fabrice Bellard	3bb4e23a8a	added skip macroblock optimization (big perf win on black regions for example) Originally committed as revision 13 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
Fabrice Bellard	de6d9b6404	Initial revision Originally committed as revision 5 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
