Michael Niedermayer	98dcbb47fa	avcodec/h264: reset list_count too in case of error in ff_set_ref_count() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	9eef9eb301	h264: check that execute_decode_slices() is not called too many times Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	bfd26b7ce6	h264: reject mismatching luma/chroma bit depths during sps parsing There is no point in delaying the check and it avoids bugs with a half-initialized context. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	9a026c7298	h264: rebuild the default ref list if the reference count changes Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	58312b2472	h264: reset data_partitioning if decoding the slice header for NAL_DPA fails If it was set before then we can end up trying to decode a slice without a valid slice header, which can lead to invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Dale Curtis	4feca2214a	h264: Clear ERContext.cur_pic when unref'ing current picture. Signed-off-by: Dale Curtis <dalecurtis@chromium.org>	11 years ago
Michael Niedermayer	6ea05ef278	avcodec/h264: remove unused variable Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Luca Barbato	4d2bb28931	h264: namespace the decode function Make much easier debugging.	11 years ago
Anton Khirnov	598ce4ab4f	h264: call av_frame_unref() instead of avcodec_get_frame_defaults(). This is a temporary workaround to allow deprecating avcodec_get_frame_defaults(). The proper solution will be using a properly allocated AVFrame in Picture.	11 years ago
Michael Niedermayer	d9339ab553	avcodec/h264: fix code that blindly dereferences NULL DPB Fixes mixed flushing and decoding NULL packets Found-by: wm4 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Vittorio Giovara	5b10ef729f	h264: parse frame packing arrangement SEI messages and save relevant stereo3d information	11 years ago
Anton Khirnov	f0259a587e	h264: check buffer size before accessing it Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	a553c6a347	lavc: use buf[0] instead of data[0] in checks whether a frame is allocated data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Anton Khirnov	9eda9d3322	h264: free the tables and uninitialize the context on flush Prevents referencing empty frames when the first packet after the flush does not contain a frame.	11 years ago
Michael Niedermayer	9e5ef1c5c3	h264: Do not treat the initial frame special in handling of frame gaps The not handling of frame gaps has lead to the lack of a dummy reference frame, which has lead to the failure of decode_slice_header() which has lead to one SEI recovery message being skiped which had introduced a slightly suboptimal recovery point for at least 1 h264 file compared to JM. Found-by: Carl & BugMaster Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	11 years ago
Michael Niedermayer	4fb1221e66	h264: reduce whitespace differences to libav Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	647adc4290	h264: factor "if(h->sei_recovery_frame_cnt >= 0)" out Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	f62dfed3de	h264: simplify frame_recovered code This is a separate commit to ease future bisecting in case it breaks something. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
John Stebbins	28096e0a80	h264: wait for initial complete frame before outputing frames This can be optionally disabled whith the "output_corrupt" flags option. When in "output_corrupt" mode, incomplete frames are signalled through AVFrame.flags FRAME_FLAG_INCOMPLETE_FRAME. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Derek Buitenhuis	58d13cea30	h264: Check all allocations Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Derek Buitenhuis	a483aae7d8	h264: Check all allocations Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Michael Niedermayer	3c9dd93faa	h264: make flush_change() set mmco_reset This ensures that frames do not get mixed on context reinits Fixes Ticket2836 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	29ffeef5e7	avcodec/h264: do not trust last_pic_droppable when marking pictures as done This simplifies the code and fixes a deadlock Fixes Ticket2927 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	65c2fe7159	avcodec/h264: call flush_change() on init This ensures that all the non zero fields get setup correctly. Alternatively their initialization could be duplicated. Fixes Ticket2738 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Clément Bœsch	b46f19100b	cosmetics: group remaining .name and .long_name. See `b2bed9325`.	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Carl Eugen Hoyos	b5f219c904	Print pix_fmt name on h264 context reinitialisation.	11 years ago
Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Ronald S. Bultje	c341f734e5	Convert multiplier for MV from int to ptrdiff_t. This prevents emulated_edge_mc from not undoing mvy*stride-related integer overflows. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
