* avcodec/cavsdec, h264*, hevc_parser: Use get_ue_golomb_31 where possibleAndreas Rheinhardt2020-07-29
| | | | | | | | | | instead of get_ue_golomb(). The difference between the two is that the latter also has to take into account the case in which the read code is more than 9 bits (four preceding zeroes + at most five value bits) long, leading to more code.

* hevc_parser: drop the use of SliceHeaderAnton Khirnov2020-06-08
| | | | | It is only used to store a few local variables within one function, which is better accomplished by just declaring them on stack explicitly.

* lavc/h2645_parse: Don't automatically remove nuh_layer_id > 0 packetsAndriy Gelman2020-01-17
| | | | | | | | | | | | | | | | | | | HEVC standard supports multi-layer streams (ITU-T H.265 02/2018 Annex F). Each NAL unit belongs to a particular layer defined by nuh_layer_id in the header. Currently, all NAL units that do not belong to a base layer are automatically removed in ff_h2645_packet_split(). Some data may therefore be lost when future filters/decoders are designed to support multi-layer streams. A better approach is to forward nuh_layer_id > 0 packets and let blocks down the chain decide how to process them. The condition to remove packets has been moved to hevcdec and cbs.

* hevc: fix race condition in max_ra/seq_decode.Ronald S. Bultje2017-05-25
| | | | | | | | | | These variables are shared between frame threads, but they are updated post-setup_finished() if a EOB/EOS slice type occurs. Moving the EOB/EOS slices to the next frame thread instance (by parsing them leading into the next picture instead of trailing behind the last picture) effectively prevents this race condition. This fixes tsan failures on hevc-conformance-NoOutPrior_A_Qualcomm_1.
