Those two video are working (cause youtube had converted them, I think).

On the other videos that are not displaying and often this is live streams (I think, youtube did not converted them to acceptable format)
these Javascript warnings with WebGL errors appear in terminal:

Also coub.com does not show any video (but only preview and loading gif). And terminal says:
