Timothy Gu	e4af9be0f4	Revert "Merge commit 'd1d7678040cd60148f97b372cb4291bcc45b2e22'" This reverts commit `796027f221`, reversing changes made to `bca30ed2b6`. Preemptive revert before further testing has been done.	9 years ago
James Almer	613c86299f	avcodec/h264dec: move ff_h264_ps_uninit prototype to h264_ps.h It's the proper place since `8c7932884d` Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
Anton Khirnov	d1d7678040	h264: fix the check for mixed IDR/non-IDR slices	9 years ago
Anton Khirnov	b13fc1e344	h264: do not pass H264Context to h264_slice_header_parse() This should make it more clear that this function does not need any decoder-global state other than the parameter sets.	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	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	19446dc5ff	h264: drop unused NAL_FF_IGNORE	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	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
Matthieu Bouron	0ea58059d6	lavc/h264_ps: add ff_h264_ps_uninit and use it	9 years ago
Clément Bœsch	34ec084b84	lavc/h264: move history parsing variable to H264ParseContext This makes h264_find_frame_end() not depend on H264Context anymore.	9 years ago
Clément Bœsch	7dd8cd1933	lavc/h264_sei: fix broken style around green metadata code	9 years ago
Clément Bœsch	5342bb624d	lavc/h264: rename GreenMetaData to H264SEIGreenMetaData Reduces diff for the next merge with Libav.	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	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	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	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
Clément Bœsch	83163577e2	lavc/h264: remove unused ff_h264_init_dequant_tables prototype Unused since `1534ef87` / `3176217c`.	9 years ago
Anton Khirnov	2e4a7bd553	h264: drop unused H264Context.gb Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago
Vittorio Giovara	41ed7ab45f	cosmetics: Fix spelling mistakes Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago
Anton Khirnov	2e5bde9565	h264: eliminate max_contexts It is always equal to nb_slice_ctx.	9 years ago
Anton Khirnov	e065279529	h264: remove an artificial restriction on the number of slice threads This limit is now unnecessary, we can easily support an arbitrary number of threads.	9 years ago
Anton Khirnov	b77fffa127	h264: make slice threading work with deblocking_filter=1 In such a case, decode the MBs in parallel without the loop filter, then execute the filter serially. The ref2frm array was previously moved to H264SliceContext. That was incorrect, since it applies to all the slices and should properly be in H264Context (it did not actually break decoding, since this distinction only becomes relevant with slice threading and deblocking_filter=1, which was not implemented before this commit). The ref2frm array is thus moved back to H264Context.	9 years ago
Anton Khirnov	370ddc7b38	h264: remove H264Context.pict_type It is not used for anything internally, just exported in the output frames. So remove the indirection and set it directly in frame_start().	9 years ago
Anton Khirnov	56087ec0a2	h264: drop a pointless indirection	9 years ago
Anton Khirnov	0e7772c5e4	h264: remove unused H264SliceContext.rbsp_buffer	9 years ago
Anton Khirnov	7f045c4429	h264: merge ff_h264_free_context() into h264_decode_end() It is no longer called from outside the h264 decoder.	9 years ago
Anton Khirnov	99c554efc8	h264: eliminate low_delay It is always unconditionally initialized in decode_postinit() and then immediately used in one place further below. All the other places where it is accessed are just useless fluff.	9 years ago
Anton Khirnov	89ae244e78	h264_refs: remove an unused parameter from ff_h264_fill_mbaff_ref_list()	9 years ago
Anton Khirnov	755f79f84c	h264_refs: make the H264Context const where possible	9 years ago

Anton Khirnov	98c97994c5	h264: decouple extradata parsing from the decoder This will allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	728d90a0c1	h264: decouple h264_sei from the h264 decoder Make the SEI parsing independent of the H264Context, to allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	c8dcff0cdb	h264: factor out calculating the POC count into a separate file This will allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	3176217c60	h264: decouple h264_ps from the h264 decoder Make the SPS/PPS parsing independent of the H264Context, to allow decoupling the parser from the decoder. The change is modelled after the one done earlier for HEVC. Move the dequant buffers to the PPS to avoid complex checks whether they changed and an expensive copy for frame threads.	9 years ago
Anton Khirnov	a6e27f7add	h264: factor out parsing the reference count into a separate file This will allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	8d0cc8ca97	h264_parser: switch to h2645_parse for NAL unescaping Remove now unused ff_h264_decode_nal().	9 years ago

Anton Khirnov	ecc31f6b08	h264: move ff_h264_check_intra[4x4]_pred_mode() to h264_parse It is shared with svq3.	9 years ago
Anton Khirnov	e481458bc3	h264: factor out pred weight table parsing into a separate file This will allow decoupling the parser from the decoder.	9 years ago
