widevine L1-support – or at least a guide / insight where problems are to get there [Feature]

[slynobody]

Is your feature request related to a problem? Please describe.

is it possible to get widevine L1 somehow? currently it is 'only' L3. (and videos seem to get dithered somehow? maybe this is an effect of L3?)

Describe the solution you'd like.

maybe you or someone else could explain what would be needed stuff / dependencies / patching-points to get L1 or near it.

Describe alternatives you've considered.

there are some dubious apks in the wild claiming to offer widevine L1-support. none of them are working (and could get you also security-issues)

Additional context

none

This is a requirement of Google to get widevine certification on a per device basis for Android. As we are a generic device tree, along with all Android x86 variants, the only thing available to us is L3 (uncertified)

Out of curiosity, there are plugins like this: https://github.com/jonas-coded/netflix_hd_patch

Is something like this possible to trick it to think it's L1?

[electrikjesus]

Maybe, but it would have to be a recent version of Netflix that is patched. And it would have to be on a per-app basis
