[libav-devel] [PATCH 3/3] mov: move stsd finalization to an appropriate place

mov_finalize_stsd_codec parses stream information from the ALAC extradata, so run it after the extradata processing is completed in mov_read_stsd. Fixes playback of 96kHz ALAC streams muxed by qaac or the reference alac encoder. Adapted from an FFmpeg patch by Hendrik Leppkes

[libav-devel] [PATCH 08/22] lavc: Add trace_headers bitstream filter

[libav-devel] [PATCH 18/22] qsvenc_hevc: Replace ad-hoc VPS writing with CBS implementation

This copies more information which should be present from the SPS. It also fixes the value of vps_temporal_id_nesting_flag, which was previously incorrect for a single-layer stream (the standard states that it must be 1, and the reference decoder barfs if it isn't). --- Tested on Linux / Skylake.

[libav-devel] [PATCH 00/22] Coded bitstream editing (v5)

Mainly minor updates. Significant additions: * H.265 metadata bitstream filter * H.265 in VAAPI is generally improved - more metadata, AUDs are added. * The VPS writing code in qsvenc is replaced, and the old code removed. * Use of anonymous unions removed. Thanks, - Mark
