Michael Niedermayer	f435d081b0	h264: Add an AVClass pointer to H264Context Sample-Id: asan_heap-uaf_3660f67_757_cov_1257014655_Hi422FR1_SONY_A.jsv Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Anton Khirnov	741b494fa8	h264: eliminate default_ref_list According to the spec, the reference list for a slice should be constructed by first generating an initial (what we now call "default") reference list and then optionally applying modifications to it. Our code has an optimization where the initial reference list is constructed for the first inter slice and then rebuilt for other slices if needed. This, however, adds complexity to the code, requires an extra 2.5kB array in the codec context and there is no reason to think that it has any positive effect on performance. Therefore, simplify the code by generating the reference list from scratch for each slice.	9 years ago
Derek Buitenhuis	d15368ee39	h264: Run VLC init under pthread_once This makes the h.264 decoder threadsafe to initialize. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Kieran Kunhya	b0017579b6	h264: Add support for Closed Caption export Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago

Anton Khirnov	5ec0bdf2c5	h264: do not update the context fields copied between threads after finish_setup() Should fix a large number of possible races with frame threading.	10 years ago
Anton Khirnov	e49e0f58e2	h264: make sure the slices do not overlap during slice threading Based on a patch by Michael Niedermayer <michaelni@gmx.at>. CC: libav-stable@libav.org Found-by: Kieran Kunhya <kierank@obe.tv>	10 years ago
Anton Khirnov	a0f2946068	h264: use properly allocated AVFrames	10 years ago
Anton Khirnov	7a4f74eed5	h264: embed the DPB in the context It now has a fixed size and is initialized only once, so there is no point in allocating it separately.	10 years ago
Anton Khirnov	11f024ef0a	h264: move freeing the escaped RBSP buffer to free_context() It does not logically belong in free_tables(), since it's not allocated in alloc_tables() and its size has nothing to do with the frame size.	10 years ago
Anton Khirnov	ee62b364be	h264: eliminate ff_h264_set_parameter_from_sps() That function currently does two things -- reinitializing the DSP contexts and setting low_delay based on the SPS values. The former more appropriately belongs in h264_slice_header_init(), while the latter only really makes sense in decode_slice_header(). The third call to ff_h264_set_parameter_from_sps(), done immediately after parsing a new SPS, appears to serve no useful purpose, so it is just dropped. Also, drop now unneeded H264Context.cur_chroma_format_idc.	10 years ago
Anton Khirnov	9d33bab583	h264: drop H264Context.ouputed_poc It is only set, but never used for anything.	10 years ago
Anton Khirnov	27b0e6ebfd	h264: drop needs_realloc It is not needed anymore since switching to refcounted frames.	10 years ago
Vittorio Giovara	6a85dfc830	lavc: Replace av_dlog and tprintf with internal macros	10 years ago
Anton Khirnov	a4d34e218f	h264: disable ER by default The way it is currently designed is fundamentally unsafe and cannot be reasonably fixed without completely rewriting it.	10 years ago
Anton Khirnov	c28ed1d743	h264: move [uv]linesize to the per-slice context While it is a per-frame variable, it is only really used in the low-level decoding code, so it is more efficient to store it in the slice context.	10 years ago
Anton Khirnov	a12d3188cb	h264: use a smaller struct for the ref lists There is no need to store a whole H264Picture, with a full AVFrame embedded in it. This should allow getting rid of the embedded AVFrame later.	10 years ago
Anton Khirnov	5bf3c0fa49	h264: drop the now unused per-slice H264Contexts	10 years ago
Anton Khirnov	51d8725a6e	h264: use the main H264Context as the parent for all slice contexts There is now no need to have per-slice copies of the H264Context.	10 years ago

Anton Khirnov	582683b6ac	h264: move remaining ER stuff into the per-slice context	10 years ago
Anton Khirnov	c377e04d8a	h264: move top_borders into the per-slice context Also change the method for allocating to the same one as used by edge_emu_buffer.	10 years ago
Anton Khirnov	36d04801ba	h264: move the scratch buffers into the per-slice context Also change the method for allocating them. Instead of two possible alloc calls from different places, just ensure they are allocated at the start of each slice. This should be simpler and less bug-prone than the previous method.	10 years ago
