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

Diego Biurrun	0f40c90984	Drop pointless assert.h #includes	9 years ago
Anton Khirnov	2e5bde9565	h264: eliminate max_contexts It is always equal to nb_slice_ctx.	9 years ago
Anton Khirnov	e3c9041cfe	h264: allocate some tables per slice contexts, not threads This is more correct and avoids wasting space when frame threading is used.	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	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	5b35b290dd	h264: remove a stale comment This comment used to apply to code that was removed.	9 years ago
Anton Khirnov	72da8d9bb2	h264_parser: remove the remaining dependencies on the h264 decoder	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	56b17a33f2	h264: stop testing whether the reference count changes in ff_set_ref_count() It is no longer necessary after `741b494fa8`	9 years ago
Anton Khirnov	e9f884416c	h264: move reading direct_spatial_mv_pred out of ff_set_ref_count() It has nothing to do with the reference count and so does not belong in this function.	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
Diego Biurrun	061dc20351	h264: Add missing ff_ prefix to internally visible h264_init_dequant_tables()	9 years ago
Anton Khirnov	ca2f19b9cc	h264: switch to h2645_parse for NAL parsing	9 years ago
Anton Khirnov	a7829a2a3f	h264: reimplement `3aa661ec5` in a more explicit way Instead of handling the problem inside NAL decoding code, add a higher level wrapper function. This should be more robust against future changes (and easier to read).	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	9b30f8dd8f	h264: remove the svq3-specific code	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
Anton Khirnov	2c6811397b	lavc: add profiles to AVCodecDescriptor The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.	9 years ago
Anton Khirnov	b09ad37c83	h264: derive the delay from the level when it's not present Fall back to maximum DPB size if the level is unknown. This should be more spec-compliant and does not depend on the caller setting has_b_frames before opening the decoder. The old behaviour, when the delay is supplied by the caller setting has_b_frames, can still be obtained by setting strict_std_compliance below normal.	9 years ago

Jake Sebastian-Jones	9469370fb3	h264: Use AVERROR return codes instead of -1 And report why it fails. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
John Högberg	b7040e67ec	h264: fix AVDISCARD_NONKEY for some interlaced content When skip_frame is set to _NONKEY the decoder skips everything except intra slices, which breaks frames that consist of an intra field together with any other field type; half the frame becomes garbage. This patch fixes the issue by letting non-intra slices through if they're part of a keyframe. Signed-off-by: Anton Khirnov <anton@khirnov.net>	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	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	440e8dd374	h264: drop a comment that carries no useful information	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	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
