Vittorio Giovara	3e3056f2a0	h264: Allow stream and container cropping at the same time The container cropping is applied only when difference is within 16 pixels, and the smallest value between the two is chosen. Bug-Id: 383 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
Andreas Cadhalpun	a4fbd55d6e	h264: er: Copy from the previous reference only if compatible Also use the frame pixel format instead of the one from the codec context, which is more robust. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Michael Niedermayer	08d006f5a8	h264: Fix HWACCEL_MAX for D3D11 Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Luca Barbato	0181ae9af2	h264: Make sure reinit failures mark the context as not initialized Bug-Id: CVE-2015-3417 CC: libav-stable@libav.org	10 years ago
Steve Lhomme	d8039ef8d2	D3D11va: add a Direct3D11 video decoder similar to DXVA2 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Anton Khirnov	a0f2946068	h264: use properly allocated AVFrames	10 years ago
Anton Khirnov	88c612e3a4	h264: merge the init and reinit paths in update_thread_context() There is no real need to handle the init case specially, everything necessary is initialized in the reinit code as well.	10 years ago
Anton Khirnov	8a66fd4026	h264: drop the reinit parameter from init_slice_header() It is only used to decide whether to call free_tables(), but that function is safe to call on an uninitialized context as well.	10 years ago
Anton Khirnov	c9ccbc7333	h264: update the current bit depth/chroma type in init_slice_header() With frame threading, it is currently only updated in the context where the change occurs, but not in any other contexts.	10 years ago
Anton Khirnov	29dcde2b87	h264: copy nal_length_size in update_thread_context It does not make sense to copy is_avc without copying this as well. This patch should not change anything for now, but will have an effect in later commits.	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	54986d6db9	h264: move context reinit lower down in update_thread_context() It uses some fields from the SPS, which is not yet set where the reinit is called currently.	10 years ago
Anton Khirnov	a6cd154463	h264: move the DPB init/uninit to init_context()/free_context() Currently, the DPB is initialized in alloc_tables() and uninitialized in free_tables(), but those functions manage frame size-dependent variables, so DPB management does not logically belong in there. Since we want the init/uninit to happen exactly once per the context lifetime, init_context()/free_context() are the proper place for this code.	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	92e0b7342c	h264_slice: constify all the uses of H264Context during slice decoding All the variables modified by this code are either per-MB arrays or have been moved to the per-slice context	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
