2016-07-24lavc/h264_ps: Be more verbose when truncating likely oversized PPS.Carl Eugen Hoyos
2016-07-11h264_ps: export actual height in MBs as SPS.mb_heightAnton Khirnov
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.

In order to be able to make SPS const in H264ParamSets, modify decode_scaling_matrices so that it returns if the scaling matrix are present in the SPS, instead of altering the input SPS structure.

2016-06-21h264: tighten the valid range for ref_frame_countAnton Khirnov
This field (which the spec calls max_num_ref_frames) must be less than or equal to MaxDpbFrames, which is at most 16.
2016-06-21h264: move the parameter set definitions to a new header fileAnton Khirnov
The PS parsing code is independent from the decoder, so it makes more sense for it to have its own separate header.
2016-06-21h264: rename h264.[ch] to h264dec.[ch]Anton Khirnov
This is more consistent with the naming of other decoders.

* 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.

2015-12-06h264: derive the delay from the level when it's not presentAnton Khirnov
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.
