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	f26a63c4ee	avcodec/h264_cabac: Tighten allowed coeff_abs range Fixes: integer overflows Reported-by: "Xiaohan Wang (王消寒)" <xhwang@chromium.org> Based on limits in "8.5 Transform coefficient decoding process and picture construction process prior to deblocking filter process" Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
Anton Mitrofanov	70946e6059	h264dec: Fix mix of lossless and lossy MBs decoding CC: libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>	7 years ago
Anton Mitrofanov	18d3f36d3c	h264_cabac: Fix CABAC+8x8dct in 4:4:4 Use the correct ctxIdxInc calculation for coded_block_flag. Keep old behavior for old versions of x264 for backward compatibility. CC: libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>	7 years ago
Wan-Teh Chang	99c5ac2039	avcodec/h264: Declare the local variable decode_chroma as const. ff_h264_decode_mb_cabac() and ff_h264_decode_mb_cavlc() are very long functions. Declaring decode_chroma as const makes it clear the variable doesn't change after initialization.

Michael Niedermayer	a3a4082599	avcodec/h264_cabac: Fix runtime error: negation of -2147483648 cannot be represented in type 'int'; cast to an unsigned type to negate this value to itself Fixes: 858/clusterfuzz-testcase-5168477042114560 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Michael Niedermayer	258763ad0e	avcodec/h264_cabac: runtime error: signed integer overflow: 2147483647 + 14 cannot be represented in type 'int' Fixes: 614/clusterfuzz-testcase-4931860079575040 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago

Anton Khirnov	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	9 years ago
James Almer	94011f994a	avodec/h264dec: fix compilation with -DTRACE Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
Anton Khirnov	6e92181bf8	h264: pass just the PPS to get_chroma_qp() It does not need the whole context. This will simplify the following commit.	9 years ago
Diego Biurrun	4f81f8dba7	Drop unnecessary golomb.h #includes	9 years ago
Vittorio Giovara	41ed7ab45f	cosmetics: Fix spelling mistakes Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago
Diego Biurrun	c11c693acc	h264: Drop broken trace debug output	9 years ago
Anton Khirnov	3176217c60	h264: decouple h264_ps from the h264 decoder Make the SPS/PPS parsing independent of the H264Context, to allow decoupling the parser from the decoder. The change is modelled after the one done earlier for HEVC. Move the dequant buffers to the PPS to avoid complex checks whether they changed and an expensive copy for frame threads.	9 years ago
Anton Khirnov	ecc31f6b08	h264: move ff_h264_check_intra[4x4]_pred_mode() to h264_parse It is shared with svq3.	9 years ago

Michael Niedermayer	e5655a32bc	avcodec/h264_cabac: Check decode_cabac_mb_mvd() for failure Fixes harmless integer overflow Fixes Ticket5150 No speedloss measured, actually its slightly faster, but please benchmark & double check this Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
