* h264_sei: parse the picture timing SEIs correctlyAnton Khirnov2020-04-10
| | | | | | | | | Those SEIs refer to the currently active SPS. However, since the SEI NALUs precede the coded picture data in the bitstream, the active SPS is in general not known when we are decoding the SEI. Therefore, store the content of the picture timing SEIs and actually parse it when the active SPS is known.
* h264_sei: use a separate reader for the individual SEI messagesAnton Khirnov2020-04-10
| | | | | This tells the parsing functions the payload size and prevents them from overreading.

| | | | | | | | | | | | | | | | | | | | The use of this SEI is for backward compatibility in HLG HDR systems: older devices that cannot interpret the "arib-std-b67" transfer will get the compatible transfer (usually bt709 or bt2020) from the VUI, while newer devices that can interpret HDR will read the SEI and use its value instead.

This fixes a -Wtype-limits warning by GCC spotted by Michael.

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>
| * 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.
* | avcodec: Use get_ue_golomb_long() when neededMark Harris2015-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_ue_golomb() cannot decode values larger than 8190 (the maximum value that can be golomb encoded in 25 bits) and produces the error "Invalid UE golomb code" if a larger value is encountered. Use get_ue_golomb_long() instead (which supports 63 bits, up to 4294967294) when valid h264/hevc values can exceed 8190. This updates decoding of the following values: (maximum) first_mb_in_slice 36863* for level 5.2 abs_diff_pic_num_minus1 131071 difference_of_pic_nums_minus1 131071 idr_pic_id 65535 recovery_frame_cnt 65535 frame_packing_arrangement_id 4294967294 frame_packing_arrangement_repetition_period 16384 display_orientation_repetition_period 16384 An alternative would be to modify get_ue_golomb() to handle encoded values of up to 49 bits as was done for get_se_golomb() in a92816c. In that case get_ue_golomb() could continue to be used for all of these except frame_packing_arrangement_id. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
