* h264: decouple h264_ps from the h264 decoderAnton Khirnov2016-04-24
| | | | | | | | | 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.

* h264: derive the delay from the level when it's not presentAnton Khirnov2015-12-06
| | | | | | | | | | | 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.

* h264: use the correct SPS during PPS parsingAnton Khirnov2015-04-05
| | | | | There is in general no reason for the currently active SPS to be the one referenced by the PPS being parsed.

* h264: reset num_reorder_frames if it is invalidAnton Khirnov2014-01-18
| | | | | | | | | 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. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: reject mismatching luma/chroma bit depths during sps parsingAnton Khirnov2014-01-06
| | | | | | | | | | 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
* h264_ps: when parsing a VUI fails, only abort when explode is setAnton Khirnov2013-10-27
| | | | | | 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.

* h264: deMpegEncContextizeAnton Khirnov2013-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* h264: improve parsing of broken AVC SPSMichael Niedermayer2012-03-13
| | | | | | | | | | | | Parsing the entire NAL as SPS fixes decoding of some AVC bitstreams with broken escaping. Since the size of the NAL unit is known and checked against the buffer end we can parse it entirely without buffer overreads.

* h264: fix HRD parameters parsingMans Rullgard2011-10-11
| | | | | | | | | | The bit_rate_value_minus1 and cpb_size_value_minus1 elements allow a wider range than get_ue_golomb() supports. This adds a get_ue_golomb_long() function supporting up to 31 leading zeros, which is the maximum for these syntax elements, and uses it in decode_hrd_parameters().

* h264: fix detection of optional trailing PPS elementsMans Rullgard2011-10-11
| | | | | | | | | | | | | | The PPS may contain a few trailing elements whose presence is only signalled by data remaining after the the mandatory part has been parsed. The current code fails to take into account the rbsp_trailing_bits() when deciding whether to parse these optional elements. Assuming no unnecessary padding bytes are passed to this function, the optional elements are present if either more than 8 extra bits remain or the remaining bits do not form a valid rbsp_trailing_bits() after the mandatory PPS elements have been parsed.

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
