What are you talking about? Video formats have a whole mad type parameter for this stuff https://jakearchibald.com/2022/html-codecs-parameter-for-av1...

It's not mandatory, and it would work without using it. The whole point is for forward compatibility support effect for sites which are very slow introducing these kind of changes.

  • It's not mandatory. But if you don't use it, the browser may select a source it cannot play.

    • Possibly, but as above, a much slower problem to solve is not in the browser support, but in sites support. Browsers in practice move way faster.
