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. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
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.

Michael Niedermayer	3aa661ec56	h264: improve parsing of broken AVC SPS Parsing the entire NAL as SPS fixes decoding of some AVC bitstreams with broken escaping.
