[Feature]: Default to AV1 codec, fallback to VP9, fallback to H264

[therealresonix]

What problem would this solve?

The AV1 codec saves bandwidth whilst delivering the highest picture quality. If the device supports this codec, it should therefore be set as the default.
If the device does not support this codec, it will switch to VP9, and if it does not support that either, it will switch to good old H.264.
This feature could, for example, be called ‘Smart Codec’.

What would you like to see?

see above :)

Alternatives considered

User can set the default codec could be an alternative

Anything else?

This could be useful for TVs
Could be also used by browsers

+1 for choosing default codec (or having the player remember your preference whenever you change it on a video).
