feat(YouTube/Video playback): add `Disable VP9 codec` setting

[inotia00]

Application

YouTube

Feature description

This is not a patch request, but a description of the feature that will be introduce in the next release.

For several months now, Google has been removing video quality higher than 480p from some older videos.

As a result, 1080p is only available to YouTube Premium subscribers on some older videos, or the video quality menu is not accessible at all.

(Of course, this is also reproducible on unpatched YouTube).

A list of available video codecs and video qualities can be easily checked with an app like YTDLnis.

As per the attached screenshot, 1080p is only available with AVC codec.

(This is why 1080p is still available on Web.)

In other words, if we force AVC codec instead of VP9 or AV1 codec, 1080p is still available.

If we force AVC codec, there are side effects, just like when using Force iOS AVC setting of Spoof streaming data patch:

• Maximum resolution is 1080p.
• Video playback will use more internet data than VP9.

Nevertheless, the Disable VP9 codec patch might be useful for some users like me who use 1080p as default.

Motivation

Some people, including myself, might want to watch videos that are only available in 360p in 1080p, despite the side effects of the patch.
