Anton Khirnov	a8cbe5a0cc	h264_ps: export actual height in MBs as SPS.mb_height Currently, SPS.mb_height is actually what the spec calls PicHeightInMapUnits, which is half the frame height when interlacing is allowed. Calling this 'mb_height' is quite confusing, and there are at least two associated bugs where this field is treated as the actual frame height - in the h264 parser and in the code computing maximum reordering buffer size for a given level. Fix those issues (and avoid possible future ones) by exporting the real frame height in this field.	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	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	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

Diego Biurrun	f4d581cda3	lavc: Deduplicate zigzag_scan table	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

Anton Khirnov	84f226a3bc	h264: use the correct SPS during PPS parsing There is in general no reason for the currently active SPS to be the one referenced by the PPS being parsed.	10 years ago

Anton Khirnov	9ecabd7892	h264: reset num_reorder_frames if it is invalid An invalid VUI is not considered a fatal error, so the SPS containing it may still be used. Leaving an invalid value of num_reorder_frames there can result in writing over the bounds of H264Context.delayed_pic.

Anton Khirnov	bfd26b7ce6	h264: reject mismatching luma/chroma bit depths during sps parsing There is no point in delaying the check and it avoids bugs with a half-initialized context. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	94603feb1b	h264_ps: when parsing a VUI fails, only abort when explode is set A VUI doesn't contain anything strictly necessary for decoding. Apparently there are many samples with truncated VUIs in the wild, this commit should allow decoding them.	11 years ago

Anton Khirnov	2c54155407	h264: deMpegEncContextize Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.
