I was surprised, too. But it did work on Raspbian buster minus one. Then I upgraded to Raspbian buster to get a more recent version of Chromium since HBO Max was blocking me based on whatever version shipped with (buster minus one). At that point I started shooting various startup flags at Chromium from the web of wizards' incantations until video started to play again. That including removing the 'f' per the incantation I mentioned. This cured video playback health but it put my mouse under some kind of latency spell. I think I could beat this level with a drowsy mouse if only I could find increased magic for the subtitles somewhere. Does anyone know if there is a Chromium arg I can use to just farm some magic?
