Summary of the bug:
Apple TV+ has very good trailers in Dolby Vision profile 5 using IPTPQc2
and Dolby Atmos. Yet, since audio is supposed to be streaming from a
different CDN than video (on both CDNs both video and audio is available
though). keepalive fails though between two domains vod-
ap2-aoc.tv.apple.com:-1 != vod-ak-aoc.tv.apple.com:-1. Maybe Issue was
here: https://github.com/yt-dlp/yt-dlp/issues/771#issuecomment-918152831
Now in practive it fails after parsing all ~200 streams but... Also, why
IS hls.js so much faster than ffmpeg??? See: https://tv.apple.com/us/show
/the-morning-show/umc.cmc.25tn3v8ku4b39tr6ccgb8nl6m (yeah, it is from
there. FFmpeg has all the same.
