2018-02-14avcodec/h264_cavlc: Set valid qscale value in ff_h264_decode_mb_cavlc()Xiaohan Wang
When ff_h264_decode_mb_cavlc() failed due to wrong sl->qscale values, e.g. dquant out of range, set the qscale to be a valid value before returning -1 and exiting the function. The qscale value can be used later e.g. in loop filter. BUG=806122 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* commit '3176217c60ca7828712985092d9102d331ea4f3d': h264: decouple h264_ps from the h264 decoder Main changes: - a local GetBitContext is created for the various ff_h264_decode_seq_parameter_set() attempts - just like the old code, remove_sps() is adjusted so it doesn't remove the pps. Fixes decode with Ticket #631 http://ffmpeg.org/pipermail/ffmpeg-user/attachments/20111108/dae58f17/attachment.mp4 but see next point as well. - ff_h264_update_thread_context() is updated to work even when SPS isn't set as it breaks current skip_frame code. This makes sure we can still decode the sample from ticket #631 without the need for -flags2 +chunks. (Thanks to Michael) - keep {sps,pps}_ref pointers that stay alive even when the active pps/sps get removed from the available lists (patch by michaelni with additionnal frees in ff_h264_free_context() from mateo) - added a check on sps in avpriv_h264_has_num_reorder_frames() to fix crashes with mpegts_with_dvbsubs.ts from Ticket #4074 http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4074/mpegts_with_dvbsubs.ts - in h264_parser.c:h264_parse(), after the ff_h264_decode_extradata() is called, the pps and sps from the local parser context are updated with the pps and sps from the used h264context. This fixes fate-flv-demux. - in h264_slice.c, "PPS changed between slices" error is not triggered anymore in one condition as it makes fate-h264-xavc-4389 fails with THREADS=N (Thanks to Michael) Merged-by: Clément Bœsch <clement@stupeflix.com> Merged-by: Michael Niedermayer <michael@niedermayer.cc> Merged-by: Matthieu Bouron <matthieu.bouron@stupeflix.com>

2016-04-24h264: decouple h264_ps from the h264 decoderAnton Khirnov
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.
2016-03-28h264: move ff_h264_check_intra[4x4]_pred_mode() to h264_parseAnton Khirnov
It is shared with svq3.
