Some YouTube videos only play audio, no video, in Edge v116
ISSUE There is an issue in the Edge 116 stable-release with some YouTube videos. Some videos that used to play without-issue in the 115 release no-longer work in the 116 release: the audio...
UPDATE 29 AUG
I've just tested today and of the eight videos YouTube displayed by-default, only three of them work in Edge (video and audio). All eight worked fine when I tested them in Firefox.
Key: green-tick = videos fully-working in Edge; red-X = videos play as audio-only
The videos that DO work are encoded as one of the following:
• vp09.00.51.08.01.01.01.01.00 (247) / mp4a.40.2 (140)
• vp09.00.51.08.01.01.01.01.00 (247) / opus (251)
The videos that DO NOT work are all encoded as follows:
• av01.0.05M.08 (398) / opus (251)
I'm guessing "av01" refers to the new "AV1" format, and it's that which is broken?
- but its not broken in other main browsers including Firefox. When will edge prove it better than others including Firefox?
