Michael Niedermayer	985aa0be82	h264: Detect POC inconsistencies and try to handle them reasonably Improves the file from Ticket2050 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch().

Janne Grunau	9e696d2e5f	h264: support frame parameter changes during frame-mt Fixes CVE-2012-2782.	12 years ago
Janne Grunau	f1d8763a02	mpegvideo: allocate scratch buffers after linesize is known Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.	12 years ago
Michael Niedermayer	14f79ba18f	h264: remove redundant parts of old slice in extradata code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	99321d1b03	h264: merge old and new "slice in extradata" checks Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	61c6eef545	h264: prevent decoding of slice NALs in extradata It is not posible to call get_buffer during frame-mt codec initialization. Libavformat might pass huge amounts of data as extradata after parsing broken files. The 'extradata' for the fuzzed sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains multiple slices.	12 years ago
Michael Niedermayer	7973a07590	h264: Improve first slice and slice type checks This prevents a null pointer dereference Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	d7599bd8e2	h264: dont mess with frame gaps on second fields. Fixes assertion failure Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	27c8337e59	h264-mt: handle NAL_DPAs before calling ff_thread_finish_setup Since a NAL_DPA can start a new frame it has to be handled before ff_thread_finish_setup is called.	12 years ago
Michael Niedermayer	3b5c0f5e36	h264: remove low_delay/has_b_frame setting code from nal loop This code is now executed in h264_set_parameter_from_sps() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	072be3e896	h264: set parameters from SPS whenever it changes Fixes a crash in the fuzzed sample sample_varPAR.avi_s26638 with alternating bit depths.	12 years ago

Janne Grunau	a394959bbe	h264: add a pointer for weighted prediction temporary buffer Reusing MpegEncContext's obmc_scratchpad for this becomes a mess with adaptive frame-mt.	12 years ago
Janne Grunau	3ab5f7dc13	h264: slice-mt: check master context for valid current_picture_ptr Fixes errors in slice based multithreading introduced in `0b300daad2`.	12 years ago
Janne Grunau	24c62ea7a5	h264: slice-mt: get last_pic_dropable from master context Fixes fate-h264-conformance-cvnlfi2_sony_h and smllwebdl.mkv from https://github.com/OpenELEC/OpenELEC.tv/issues/1557 .	12 years ago

Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	12 years ago
Janne Grunau	0b300daad2	h264: error out on unset current_picture_ptr for h->current_slice > 0 Fixes a segfault with fuzzed sample sample_varPAR_s11622_r001-02.avi. CC: libav-stable@libav.org	12 years ago

Janne Grunau	c1fcf563b1	h264: check context state before decoding slice data partitions Fixes mov_h264_aac__Demo_FlagOfOurFathers.mov.SIGSEGV.4e9.656. Found-by: Mateusz "j00ru" Jurczyk CC: libav-stable@libav.org	12 years ago
Michael Niedermayer	93b89868e1	h264: support invalid annex B in mp4 Fixes Ticket1914 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	d5e83122bd	h264: set Picture.owner2 to the current thread This does not seem to have an effect currently. Fate-h264 passes with THREADS=1..16 and both threading types as before. It fixes however a segfault during error resilience with my adaptive-frame-mt patchset. A picture in use during error resilience gets realloced in another thread in the fuzzed sample sample_varPAR.avi_s226019.	12 years ago
Janne Grunau	6e5cdf2628	h264: check ref_count validity for num_ref_idx_active_override_flag Fixes segfault in the fuzzed sample bipbop234.ts_s226407. CC: libav-stable@libav.org	12 years ago
Janne Grunau	150b2361ca	h264: add missing new line to log message	12 years ago
Sergio Garcia Murillo	ec51b3308e	h264: Fix minor bug in h264.c error trace Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	706acb558a	h264: enable low delay only if no delayed frames were seen Dropping frames is undesirable but that is the only way by which the decoder could return to low delay mode. Instead emit a warning and continue with delayed frames. Fixes a crash in fuzzed sample nasa-8s2.ts_s20033 caused by a larger than expected has_b_frames value. Low delay keeps getting re-enabled from a presumely broken SPS. CC: libav-stable@libav.org	12 years ago
Michael Niedermayer	ba353436a3	h264: dont stop parsing NALs without cleanup on DPC. Fixes a deadlock with frame threads Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	4fecc3cf09	h264: Skip odd NALs in extradata, prevent undefined behavior Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	e6160bda98	h264: Fix parameters to ff_er_add_slice() call s->mb_x is reset to zero a couple of lines above. It does not make sense to call ff_er_add_slice() with 0 as endx when the end of the macroblock row was reached. Fixes unnecessary and counterproductive error resilience in https://bugzilla.libav.org/show_bug.cgi?id=394. CC: libav-stable@libav.org	12 years ago
Janne Grunau	60b6b8c019	h264: always check ref_count for validity Fixes a crash with zuffed files.	12 years ago
Paul B Mahol	011f3892ff	h264: use designated initializers for AVClass Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Diego Biurrun	f75f4194d1	Restructure av_log_missing_feature message Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.	12 years ago
