If you value freedom (your AND mine) don't do it.

I know about EME and why is bad. But What is the relationship of MSE with EME? Does this option also enable EME?

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 access the MSE API, so that's a problem on its own. There's also the problem that the software is being automatically installed into your browser:

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 (VP9)
    • 1280x720, video/mp4
    • 1280x720, video/webm (VP9)
    • 854x480, video/mp4
    • 854x480, video/webm (VP9)
    • 640x360, video/mp4
    • 640x360, video/webm (VP9)
  • Audio:
    • audio/mp4
    • audio/webm (Vorbis)
    • audio/webm (Opus)

The YouTube scripts choose one video-only file and one audio-only for download and plays them together in sync. When you switch a video from/to full screen the video-only file changes, but the audio stays the same.

The video-only file probably changes during other circumstances too, like when the Internet connection isn't fast enough, but I'm not sure.

YouTube also has typical audio+video files witch work without the MSE API. But for some reason they don't offer audio+video files which are above 1280x720 (720p) in resolution. The 1280x720 is the highest quality without the MSE API.

Browser like Firefox/Abrowser might come with MSE capabilities disabled by default, because their MSE implementation is still in a experimental stage.

I hope that was useful info! ;)

MSE != EME, however in YouTube's case the Javascript code that they use MSE with is of course non-free.
