10257,FFmpeg does not recognise dolby vision hevc tags,Caleb Evans,,"Summary of the bug:
FFmpeg does not recognise the dvh1 or dvhe tags for HEVC, which are hvc1 and hev1 samples with Dolby Vision encoding, as here: [https://developer.apple.com/documentation/http_live_streaming/http_live_streaming_hls_authoring_specification_for_apple_devices/hls_authoring_specification_for_apple_devices_appendixes]

When attempting to use the tag the following output is produced:
{{{
[mp4 @ 0x15770bf00] Could not find tag for codec hevc in stream #0, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:2 -- 
}}}
How to reproduce:
{{{
% ffmpeg -i input.mkv -c:v copy -tag:v dvh1 -c:a copy -c:s mov_text -strict unofficial output.mp4
ffmpeg 5.1.2
}}}",defect,new,normal,ffmpeg,unspecified,,hevc,Dominik Mierzejewski,,,0,0
