Andreas Rheinhardt	2934a4b9a5	Remove unnecessary avassert.h inclusions Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	cc2a9509ce	libavcodec, libpostproc: Remove outcommented START/STOP_TIMER as well as includes of libavutil/timer.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Michael Niedermayer	a53c4f3689	avcodec/ffv1: Simplify update_vlc_state() About 0.5% faster Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	6 years ago
Michael Niedermayer	5d0139d5f0	avcodec/ffv1: Simplify fold() No speed difference, or slightly faster (the difference is too small so it may be noise that this appears faster) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	6 years ago
Michael Niedermayer	449cdfa687	avcodec/ffv1: Increase the maximum number of slices to 1024 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago

Michael Niedermayer	ce2217b25e	avcodec/ffv1: add AV_PIX_FMT_GBRP16 support Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Michael Niedermayer	74314f1f5f	avcodec/ffv1: template functions to allow data types different from int16_t This is required for >= 16bit RGB support I tried it without templates but its too much duplicated code Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Vittorio Giovara	96c373c770	lavc: Move context_model to codec private options This option is only used by ffv1 and ffvhuff. It is a very codec-specific option, so deprecate the global variant. Improve documentation a little. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Michael Niedermayer	1c878474fb	avcodec/ffv1enc: unbreak -coder option This fixes a segfault caused by moving the coder option and changing its semantics Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	4bb1070c15	ffv1: Explicitly name the coder type FFv1 uses two types of coders, golomb and range with two different tables. This is exposed this in a rather convoluted way, for example mentioning to set coder type 1 while initializing the variable 'ac' to 2, because encoder does not use range coder with default table. Appropriate internal coder type values have been added and used in any check rather than using raw numbers. Initialization of avctx.coder_type in ffv1dec is removed because this field is encoder only. An unneeded validation check in the encoder is dropped too.

Michael Niedermayer	aa6c43f3fd	avcodec/ffv1: seperate slice_count from max_slice_count Fix segfault with too large slice_count Fixes Ticket4879 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Vittorio Giovara	10a9149de2	ffv1enc: Keep coded_frame.key_frame a write-only variable	9 years ago
Vittorio Giovara	6503cbf842	ffv1enc: Add const attribute to input frame warning: assigning to 'AVFrame ' (aka 'struct AVFrame ') from 'const AVFrame ' (aka 'const struct AVFrame ') discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]	10 years ago
James Almer	ba625dd8a1	avcodec: use av_mod_uintp2() where useful Reviewed-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: James Almer <jamrial@gmail.com>	10 years ago
Diego Biurrun	cd832f032f	ffv1: Drop bogus dependency on dsputil ffv1 does not use any part of the dsputil framework.	11 years ago
Carl Eugen Hoyos	5968415156	Define ff_log2_run[] in libavcodec/internal.h. This avoids defining the array with different sizes in different source files.	11 years ago
Michael Niedermayer	0e575c24d6	ffv1.4: use 2 coefficients for calculating the Y plane in the RCT 0-0.7% improved compression Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	7854d2d251	avcodec/ffv1: support adjusting the g vs r + b coefficient in the RCT about 1% better compression Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	a6064b12b4	ffv1: use the AVFrame API properly.	11 years ago

Michael Niedermayer	d9b0b54a5f	ffv1: rename minor to micro version the version is 1.3.4 which makes 4 micro and not minor Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	a0c0900e47	ffv1dec: Support frame threading with gop > 1 This is about 20-30% faster than slice threading Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	e4255eaf47	ffv1: split decoder and encoder This is not based on lucas work due to code divergence (its less work this way than trying to merge from a split based on 2 years outdated code) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
