Timothy Gu	f297d1e9e5	h264dec: Fix indentation	9 years ago
Timothy Gu	826c780c12	Revert "Revert "Merge commit 'd1d7678040cd60148f97b372cb4291bcc45b2e22'"" This reverts commit `e4af9be0f4` and redoes `796027f221`. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
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
Anton Khirnov	58640fe89e	h264: handle frame recovery in h264_field_start() This is a more appropriate place for this. H264Context.recovery_frame is shared between frame threads, so modifying it where it is right now is invalid.	9 years ago
Anton Khirnov	e26c64148b	h264: discard slices of redundant pictures right after parsing the slice header Going through the whole decoder initialization process for a slice we are not going to decode is unnecessary and potentially dangerous.	9 years ago
Anton Khirnov	606fb6c032	h264: call the hwaccel frame_start() from h264_field_start() This is a more appropriate place for it.	9 years ago
Anton Khirnov	d1d7678040	h264: fix the check for mixed IDR/non-IDR slices	9 years ago
Anton Khirnov	bc7f426851	h264: drop tests whether the codec id is AV_CODEC_ID_H264 Those are unused remnants of the old SVQ3 code.	9 years ago
Anton Khirnov	5c2fb561d9	h264: add H264_ prefix to the NAL unit types This will prevent conflicts e.g. in code that deals with both h264 and hevc.	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	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	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
Vittorio Giovara	187d719760	h264: Support AV_PKT_DATA_NEW_EXTRADATA	9 years ago
Clément Bœsch	5342bb624d	lavc/h264: rename GreenMetaData to H264SEIGreenMetaData Reduces diff for the next merge with Libav.	9 years ago
Clément Bœsch	fef89aae98	lavc/h264: move green meta logging out of the sei decoding This will simplify the next Libav merge where SEI decoding doesn't have access to the debug level anymore.	9 years ago

Michael Niedermayer	641dccc2aa	avcodec/h264: Check init_get_bits8() for failure Fixes CID1361935 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Hendrik Leppkes	d6f92103e0	h264: do not return an error when NAL parsing of extradata failed Fixes AnnexB samples with broken extradata, but proper in-band parameter sets Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Vittorio Giovara	41ed7ab45f	cosmetics: Fix spelling mistakes Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago
Michael Niedermayer	1ef267b83f	avcodec/h264: Put the removed SPS handling code back reverts one hunk from `7966ddfc0b` The new code from `7966ddfc0b` only covers extradata based SPS Fixes: ffplay -ss 13 58af5798-fa2c-42a2-997d-dc8e49de2d8a.flv Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	566d64d4fb	avcodec/h264: Only recover from reference pictures Fixes spec compliance Fixes Ticket5346 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	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
Ivan	3a727606c4	avcodec/h264: Fix for H.264 configuration parsing Sometimes video fails to decode if H.264 configuration changes mid stream. The reason is that configuration parser assumes that nal_ref_idc is equal to 11b while actually some codecs but 01b there. The H.264 spec is somewhat vague about this but it looks like it allows any non-zero nal_ref_idc for sps/pps. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	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
