Carl Eugen Hoyos	05503cee00	Since lowres == crop for bmp, remove it to avoid confusion. Originally committed as revision 26384 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	1b3e43e4fd	Fix overflow in pred16x16_plane x86 simd code. Fixes issue 2547. Originally committed as revision 26381 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	b9af15402d	Remove evil timers that snuck their way into r26375. Originally committed as revision 26377 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	fb2734c8a6	Fix r26375 on non-x86. Originally committed as revision 26376 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	f14bdd8e75	H.264: Partially inline CABAC residual decoding Improves CABAC performance about ~1.2%. Trick originates from x264 and has also been used in ffvp8. It's useful because coded block flags are usually zero, so it helps to have the early termination inlined into the main function. Originally committed as revision 26375 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Frank Barchard	925aa96915	Second hunk from secrity fix from google. The hunk is not fully understood but it just makes a check tighter so its safer for us to apply until it is fully understood. Might fix issue 2550 (and Chrome issue 68115 and unknown CERT issues). Our bugtracker issue though should stay open until this has been fully investiagted Patch by Frank Barchard, fbarchard at google Originally committed as revision 26368 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Sascha Sommer	f734671925	do not read over the end of the packet fixes issue 2543 Originally committed as revision 26367 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Frank Barchard	13184036a6	Check rangebits to avoid a possible crash. Fixes issue 2548 (and Chrome issue 68115 and unknown CERT issues). Patch by Frank Barchard, fbarchard at google Originally committed as revision 26365 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Kostya Shishkov	03ec42aa1c	Change some band size calculations in Bink decoder to use width in blocks instead of real width, this fixes decoding of some Bink files with odd width. Originally committed as revision 26364 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Reimar Döffinger	b0c8b8a69d	Lagarith: fix decoding of one-coloured frames by reading the per-plane color value instead of always taking 0 (resulting in green frames). Fixes issue issue2531. Originally committed as revision 26363 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Daniel Kang	eb40d7ffa7	Check symbol validity to avoid a crash, fixes issue 2523. Patch by Daniel Kang, daniel.d.kang at gmail Originally committed as revision 26360 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	0db5d2b09e	cosmetics: spacing, line wrap, and remove unneeded braces Originally committed as revision 26359 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	964f2cf2a0	Process all EXP_REUSE blocks at once in exponent_min(). 43% faster in function encode_exponents(). Originally committed as revision 26358 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	7d87d56ff8	Take advantage of per-channel exponent and exponent strategy layout to simplify and speed up encode_exponents(). 8% faster in function. Originally committed as revision 26357 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	5bff8590f3	Simplify compute_exp_strategy() by passing a pointer to all exponents and exponent strategies for a single channel to compute_exp_strategy_ch(). This allows for removal of the temporary pointer arrays. Originally committed as revision 26356 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	4b90c35d74	Use a local variable in the inner loop of group_exponents() to simplify the code. Originally committed as revision 26355 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	a281c6509f	cosmetics: remove unneeded braces Originally committed as revision 26354 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	5fc2e0075d	cosmetics: rename block_num to blk for variable name consistency Originally committed as revision 26353 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	0429e4a6ca	Move exp_strategy from AC3Block to AC3EncodeContext in order to arrange by channel first, then by block. Originally committed as revision 26352 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	7cc4be58b4	Rearrange exponent buffer to group all blocks for a single channel together. This will allow for faster and simpler processing of all blocks at once. Originally committed as revision 26351 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	2a1f431d38	H.264/SVQ3: make chroma DC work the same way as luma DC No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	290fabc684	Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients. Doesn't help speed as there isn't an asm implementation yet, but consistency is a good thing. Originally committed as revision 26348 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Sascha Sommer	3cdf69eefa	also support decoding of AVPackets with multiple wma packets fixes issue 2539 Originally committed as revision 26346 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	65344775b8	H.264: Remove useless arg to chroma_dc_dequant_idct_c Originally committed as revision 26345 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	ec3233a855	Fix ff_pw_3 alignment. Originally committed as revision 26344 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	2e18660115	Fix SVQ3 Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	bd11c7a1a8	Remove outdated comment in h264dsp.h Since we no longer have non-transposed scantables, the problem it warns about no longer exists. Originally committed as revision 26339 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	0d1d01cf70	Reindent after r26337. Originally committed as revision 26338 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	5657d14094	H.264: switch to x264-style tracking of luma/chroma DC NNZ Useful so that we don't have to run the hierarchical DC iDCT if there aren't any coefficients. Opens up some future opportunities for optimization as well. Originally committed as revision 26337 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	19fb234e4a	H.264: split luma dc idct out and implement MMX/SSE2 versions About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	ca32f7f208	H.264: eliminate non-transposed scantable support. It was an ugly hack to begin with and didn't give any performance. NOTE: this patch opens up some future simplifications to be made (such as removing some of the scantables from H264Context) but doesn't take advantage of them yet. Originally committed as revision 26329 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
