Hi there!
Opera 48.0.2685.52 (PGO)
Win10 Version 1607 x64 (latest updates installed)
Radeon Software 17.10.3 (also latest)
Codec pack for Win10x64 installed, flashplayer installed, permission to use flash granted, in chrome all works fine.

But, while trying to play video directly or using autoplay on twitter or coub sites, the message appearing: "The media content could not be played" and "Uncaught (in promise) DOMException: Failed to load because no supported source was found." in console.

I've seen some mystic treads here about somelike troubles earlier, but no solution.

So what should I do to stay with Opera (I'm still badly beaten after refusal from presto, so I have so little patience )
Deeeevs?
