Description
Summary of the bug:
How to reproduce:
ffmpeg -i test.mp4 -c:v copy -c:a copy -map v:0 -map a:0 -tag:v hvc1 -master_pl_name index.m3u8 -f hls "%v/index.m3u8" 6.1.1 Built on macOS with homebrew
The tier is hard coded to 4 and I'd be glad to submit a patch to fix this, but need some guidance on where the value should be pulled from:
