There is no VP9 decoding in Safari in any other version than Big Sur.Any love for Safari 14 on Mojave? I can play 4k 60fps videos in Chrome absolutely flawless, but Safari can't even handle 1080p60 videos without tons of freezing and stuttering.
I enabled the WebRTC vp9 codec in the developer menu but still can't even see an option for 4k on Safari 14. 1080p60 still stutters.
Since last Big Sur update I can’t watch Amazon Prime videos/movies on either Safari app although they play perfectly on Chrome browser. Any suggestions?
