HEVC has a very wide support for hardware acceleration while AV1 barely has any, especially for encoding. That's important, especially on battery-powered device

- Diti 3y agoFollowing that rationale, why haven’t we kept using H.264, when H.265 started existing?
- crazygringo 3y agoWe absolutely did. H.265 took many years to gain traction, precisely because h.264 hardware decoding was widespread but h.265 hardware decoding wasn't. Codecs simply don't take off in a big way until the hardware decoding becomes widespread. And video sites will maintain dual streams for many years, to continue supporting older hardware.

- JamesSwift 3y ago_everyone_ uses 264 as the baseline fallback because every device under the sun supports it.
- Deukhoofd 3y agoThat very much depends. In browsers, the interface most users use nowadays, that is the complete opposite, where HEVC is not widely supported while AV1 is.
- grishka 3y agoSupported and supported with hardware decoding are different things. No one likes when their device gets toasty and runs out of charge in an hour.
