- KRAKRISMOTT 3y agoBut no encoding :(
- heavyset_go 3y agoThis extension lets you enable/disable codecs on YouTube[1]. It's also available for Chromium-based browsers, as well. From what I've seen, though, is that M3 machines tend to consume more power than the M1 generation.

- lxgr 3y agoI believe Youtube just uses VP9 if you don't have AV1 hardware decoding. At least that's what consistently happens on my Mac using various browsers.
- netol 3y agoCould AV1 be more costly to decode, even in hardware, compared to VP9?
- lights0123 3y agoThere is no web standard to list what codecs are hardware accelerated—good for fingerprinting resistance, bad for battery.
- lxgr 3y agoBrowsers can just limit the codecs they claim to support to those that the system supports in hardware. I believe that's what Safari did for a while with VP8 or VP9 – it was only available while plugged in on my old Mac if I remember correctly. There was a developer option called "support VP9 even on battery power" or something similar.
- miyuru 3y agoYou can force AV1 through YT settings. https://www.youtube.com/account_playback https://www.youtube.com/account_playback
- KeplerBoy 3y agoIs AV1 more energy efficient than h264? Sure, AV1 is the better, newer codec, but h264 has been around for a long time and is certainly implemented very efficiently in the HW decoder.
