* avcodec/h2645_parse: Move ref_idc further up in H2645NALAndreas Rheinhardt2021-12-16
| | | | | | | | This puts it directly near the NALU type which is more natural and furthermore reduces the size of the structure because it can be placed in padding (on 64-bit systems). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/h2645_parse: Remove H2645NAL.rbsp_bufferAndreas Rheinhardt2021-12-16
| | | | | | | | | | Forgotten in 03b82b3ab9883cef017e513c7d0b3b986b3b3e7b. (Moving data to the front is only done to make existing initializations like H2645NAL nal = { NULL } not emit int->pointer conversion warnings.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* Remove/replace some unnecessary avcodec.h inclusionsAndreas Rheinhardt2021-07-22
| | | | | | | Also remove other unnecessary headers and include headers directly while at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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.

* h2645_parse: Make ff_h2645_packet_split reference-compatibleAndreas Rheinhardt2019-01-23
| | | | | | | This is in preparation for a patch for cbs_h2645. Now the packet's rbsp_buffer can be owned by an AVBuffer. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@googlemail.com>
* cbs_h2645: Avoid memcpy when splitting fragmentAndreas Rheinhardt2018-11-22
| | | | | | | | | | | | Now memcpy is avoided for NAL units that don't contain 0x03 escape characters. Improves performance of cbs_h2645_fragment_add_nals from 36940 decicycles to 6364 decicycles based on 8 runs with a 5.1 Mb/s H.264 sample (262144 runs each).
