I wish mpv was an option on everything. It has been lovely and reliable for years (never fails on PC, plays all of these fine).
Thanks for testing! And for lots of info to check out and digest. Does your Fire Stick 4K Max usually directly play AV1 fine? I’ve yet to try, but see Fire OS is Android based as well. I forgot to test non-TV Android (Pixel 6a here), but yes it’s doing the same (black screen, audio only), even JF fails on half (BR49, Midsommar, Oblivion).
Any guesses as to why these files are problematic? I have not found any significant differences (via MediaInfo) versus playable AV1 files. It doesn’t help that AV1 encoding settings and metadata are not saved to the stream (like AVC, HEVC).
