Vittorio Giovara	271ce76d31	h264: Parse registered data SEI message and AFD value Partially based on code by Marton Balint and Kieran Kunhya. 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
Kieran Kunhya	22291c372f	avcodec: Add support for per-frame AFD output in h264 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Andreas Cadhalpun	1189af4292	h264: update avctx width/height/pix_fmt when returning frame Inconsistencies between the dimensions/pixel format of avctx and the frame can confuse API users. For example this can crash the demuxing_decoding example. Back up the previous values and restore them, when decoding the next frame. This is necessary, because these can be different between the returned frame and the last decoded frame.

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

Michael Niedermayer	0346783c98	avcodec/h264.h: Drop unused macro Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	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
