@3arn0wl In the link given by @libremax, there is a chapter about the new video player.
It's stated there that live streaming won't have been possible without a new video player.
Hence I understand that live streaming won't be possible until the new video player is widely spread and probably even later.
And I agree this would be nice to have live news from UBPorts using a free alternative to youtube
