* avcodec/h264_slice: don't copy frame data during error concealmentJames Almer2021-03-11
| | | | | | | | | In addition to the fact that av_image_copy() cannot handle hardware pixel formats, h->short_ref[0]->f may not be writable at this point. Based on a patch by Hendrik Leppkes. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/h264_slice: fix undefined integer overflow with POC in error concealmentMichael Niedermayer2020-10-18
| | | | | | | | | | Alternatively the POC could be changed to 64bit. the large values seem to be within what is allowed.

* h264_ps: make the PPS hold a reference to its SPSAnton Khirnov2020-04-10
| | | | | | | | It represents the relationship between them more naturally and will be useful in the following commits. Allows significantly more frames in fate-h264-attachment-631 to be decoded.
* 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.
* h264dec: do not export the chroma sample location immediately on parsing the SPSAnton Khirnov2020-03-20
| | | | | This SPS is not necessarily the one that will be used. Export the chroma location along with all the other SPS properties.

* avcodec/h264_slice: set the SEI parameters early on the AVCodecContextSteve Lhomme2019-07-14
| | | | | | | | | It's better to do it before the buffers are actually created. At least in VLC we currently don't support changing some parameters dynamically easily so we don't use the information if it comes after the buffer are created.

| | | | | | | | | Create SMPTE ST 12-1 timecodes based on H.264 SEI picture timing info. For framerates > 30 FPS, the field flag is used in conjunction with pairs of frames which contain the same frame timestamp in S12M. Ensure the field is properly set per the spec.

| | | | | | | | | | | | | h264_slice_header_init during thread init If we don't copy this value first, it is seen as 0 by h264_slice_header_init, due to zero-allocation of the new context, triggering an old hack that multiplied the denominator by 2 for files produced by old x264 versions, but only if more than one thread was used.

* h264_slice: Fix return of incomplete frames from decoderJohn Stebbins2018-06-28
| | | | | | | | | | | When not using libavformat for demuxing, AVCodecContext.has_b_frames gets set too late causing the recovery frame heuristic in h264_refs to incorrectly flag an early frame as recovered. This patch sets has_b_frames earlier to prevent improperly flagging the frame as recovered. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | | | | | | | | | | | | 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.

| * h264dec: be more explicit in handling container croppingAnton Khirnov2017-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | The current condition can trigger in cases where it shouldn't, with unexpected results. Make sure that: - container cropping is really based on the original dimensions from the caller - those dimenions are discarded on size change The code is still quite hacky and eventually should be deprecated and removed, with the decision about which cropping is used delegated to the caller.
