As I understand, YouTube uses the Media Source Extensions API to change video
and audio quality/resolutions during playback. For example, a given YouTube
video comes in several audio-only and video-only files, like this:
Video:
1920x1080, video/mp4
1920x1080, video/webm
MSE != EME, however in YouTube's case the Javascript code that they use MSE
with is of course non-free.
If you value freedom (your AND mine) don't do it.

Media Source Extensions is not the same as Encrypted Media Extensions. It can
be used for digital restrictions, but as far as I understand, it's primarily
used for other things. I don't know what YouTube uses it for.
In any case, it is proprietary JavaScript code which YouTube is using to
I know about EME and why is bad. But What is the relationship of MSE with
EME? Does this option also enable EME?
type in status bar:

Than refresh Abrowser.
