Anton Khirnov	1cf2f3d334	h264_sei: drop an unnecessary h264dec.h include The code does not depend on the h264 decoder anymore and only needs information from h264_ps	9 years ago
Anton Khirnov	b24dafe105	lavc: drop unnecessary h264dec.h includes	9 years ago
Anton Khirnov	70b1dcef2d	h264: tighten the valid range for ref_frame_count This field (which the spec calls max_num_ref_frames) must be less than or equal to MaxDpbFrames, which is at most 16.	9 years ago
Anton Khirnov	f638b67e57	h264: move the parameter set definitions to a new header file The PS parsing code is independent from the decoder, so it makes more sense for it to have its own separate header.	9 years ago
Anton Khirnov	4e2f621248	svq3: stop using H264Picture The SVQ3 decoder has been decoupled from the H.264 decoder, so it can now use its own data type.	9 years ago
Anton Khirnov	251cbb4400	h264: create a new header for common h264 definitions Move the NAL unit types into it. This will allow to stop including the whole decoder-specific h264dec.h in some code that is unrelated to the decoder and only needs some enum values.	9 years ago
Anton Khirnov	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	9 years ago
Anton Khirnov	f651c6a259	h264: factor out setting frame properties / side data Right now this code is mixed with selecting the next output frame. Move it to a separate function called from h264_field_start(), which is a more appropriate place for this.	9 years ago
Anton Khirnov	19446dc5ff	h264: drop unused NAL_FF_IGNORE	9 years ago
Anton Khirnov	bcd91f1644	h264: move a per-field block from decode_slice_header() to field_start() This is a more appropriate place for it.	9 years ago
Anton Khirnov	17e7c03e12	h264: only allow ending a field/starting a new one before finish_setup() Doing this after ff_thread_finish_setup() is called is invalid and can conflict with reads from the other thread.	9 years ago
Anton Khirnov	debca90863	h264: store {curr,max}_pic_num in the per-slice context While the value of those variables will be constant for the whole frame, they are only used in two functions called from slice header decoding. Moving them to the per-slice context allows us to make the H264Context passed to slice_header_parse() constant.	9 years ago
Anton Khirnov	f966498e43	h264: decode the poc values from the slice header into the per-slice context Copy them into the decoder-global context in field_start(). This avoids modifying the decoder-global context during bitstream parsing.	9 years ago
Anton Khirnov	54dd9b1cdd	h264: set mb_aff_frame in frame_start() Avoid unnecessary modification of the decoder-global state in per-slice code.	9 years ago
Anton Khirnov	8d36932c8d	h264: move the block starting a new field out of slice_header_parse() There is no bitstream parsing in that block and messing with decoder-global state is not something that belongs into header parsing. Nothing else in this function depends on the value of current_slice, except for two validity checks. Those checks are also moved out of slice_header_parse().	9 years ago
Anton Khirnov	b25cd7540e	h264: pass a H2645NAL to slice header decoding Replace the decoder-global nal_unit_type/nal_ref_idc variables with the per-NAL ones. The decoder-global ones still cannot be removed because they are used by hwaccels.	9 years ago

Jerome Martinez	ec9f04423b	ffv1: Error out on unsupported format Transparency is supported only by YUV and within specific bit depths.	9 years ago
Vittorio Giovara	187d719760	h264: Support AV_PKT_DATA_NEW_EXTRADATA	9 years ago
Vittorio Giovara	75872d77d2	lavc: Document AV_PKT_DATA_NEW_EXTRADATA	9 years ago
Martin Storsjö	f1a9eee41c	x86: Add missing movsxd for the int stride parameter Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Diego Biurrun	84b2d3fb68	h264: Drop unused function check_opcodes()	9 years ago
Vittorio Giovara	05a4bacbf7	avpacket: Error out when creating 0-sized side data This mimics the behaviour of other av_*_new_side_data(). This is not caught by the malloc check, since padding is always added to the allocated size. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Anton Mitrofanov	a833ff68f6	h264: Fix decoding delay for Intra only streams Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Anton Khirnov	90f469aa2b	lavc: add H.264 MVC profiles	9 years ago
Anton Khirnov	61f168ae34	h264: factor out setting the parameter sets for a frame	9 years ago
Anton Khirnov	6e92181bf8	h264: pass just the PPS to get_chroma_qp() It does not need the whole context. This will simplify the following commit.	9 years ago
Anton Khirnov	d1f539c97e	h264: merge the two reinit blocks in slice_header_parse() The only difference is that the first of them contains a ff_h264_flush_change() call. While that is not necessary in the second block, it should cause no problems either. Reduce the verbosity of the reinit log message from info to verbose, since now it will be displayed during every decode session.	9 years ago
Anton Khirnov	3fba16ecd9	h264: factor starting a new field out of parsing the slice header	9 years ago
Anton Khirnov	bec993381c	h264: postpone generating the implicit MMCOs Do it right before the MMCOs are applied to the DPB. This will allow moving the frame_start() call out of the slice header parsing, since generating the implicit MMCOs needs to be done after frame_start().	9 years ago
Anton Khirnov	2d410ebbaa	h264: decode the MMCOs into per-slice contexts They are stored in the slice header, so technically they are per-slice (though they must be the same in every slice). This will simplify the following commits.	9 years ago
Anton Khirnov	39ab2ea531	h264: rename mmco_index to nb_mmco The variable stores the number of mmco entries, so the current name is misleading.	9 years ago
Anton Khirnov	7ab5d577a9	h264: move initializing the slice start out of h264_slice_header_parse()	9 years ago
Anton Khirnov	4cec43a9ee	h264: move calculating the POC out of h264_slice_header_parse() This function does not do any bitstream parsing and it depends on the current frame being allocated, so this will allow the frame_start() to be moved out eventually.	9 years ago
Anton Khirnov	6dd996c7c8	h264: move building the reference list out of h264_slice_header_parse() This does not do any bitstream parsing and will allow moving out other code in later commits.	9 years ago
Anton Khirnov	0bad254300	h264: move initing the implicit pred weight table out of h264_slice_header_parse() It depends on the reference list, so this will allow moving out the reference list construction and consequently other code it depends on.	9 years ago
Anton Khirnov	ed9a20ebe4	h264: split reading the ref list modifications and actually building the ref list This will allow postponing the reference list construction (and by consequence some other functions, like frame_start) until the whole slice header has been parsed.	9 years ago
Anton Khirnov	fa57059079	h264: move initialising the implicit pred weight table for MBAFF Do it where the normal implicit table is initialised.	9 years ago
Anton Khirnov	7b50d60442	h264: call ff_h264_fill_mbaff_ref_list() when constructing the normal ref list There is no real reason to call it separately.	9 years ago
Anton Khirnov	b16e9b9ac9	h264: move initialising the explicit pred weight table for MBAFF Currently it's done in the code that initialises the ref list for MBAFF, which is not a logical place for it. Move it to the function that parses the pred table from the bitstream, which is analogous to what is done for the implicit weight table as well.	9 years ago
Anton Khirnov	b93c0aed79	h264: drop an outdated comment	9 years ago
Anton Khirnov	77a1e2c5f8	h264: move direct mode inits out of h264_slice_header_parse() This code does not do any bitstream parsing, it just initializes some internal state.	9 years ago
Anton Khirnov	d06e4d8aab	h264: start splitting decode_slice_header() That function is currently very long and entangles bitstream parsing and decoder configuration. This makes the code much harder to read than necessary. Begin splitting the code that configures the decoder state based on the slice header information from the parsing of the slice header.	9 years ago
Mark Thompson	2940e196c5	vaapi_h265: cu_qp_delta should not be used in constant-QP mode	9 years ago
Mark Thompson	02fa1ad926	vaapi_h264: Add source version identifier as unregistered SEI Contains the libavcodec version, the VAAPI version and the libva driver vendor string.	9 years ago
Mark Thompson	48e2967cd5	vaapi_h264: Add support for SEI messages Send buffering_period and pic_timing messages when in modes targetting bitrate. Also adds NAL HRD parameters to VUI.	9 years ago

Mark Thompson	081961f819	vaapi_h264: Add support for VUI parameters Supports aspect ratio, colour format and timing information.	9 years ago
