Really? I have never need to specifically enable it.

Our warning page says so (bullet c):
https://www.torproject.org/download/download#warning

Some videos actually work after this.
 
Some videos don't automatically work, but if you go to share->embed, and get
the embed URL, they do. But most videos I try work for HTML5 without enabling.
Curious.

I did not know about this. It's a lot better to remove the "v" variable and use /embed/VideoID instead of joining the html5 test because it will make every video play.

For example:

This video won't play even if you join the html5 test page.
https://www.youtube.com/watch?v=gjK1lUA6mGk

but using embed it will work:

Thanks!
