Well using Libre.Video on NewPipe turned out to be a bust. It only plays Local video, everything on Recently added and Trending fails.
I tried to use Fedilab but it wont let me lurk, requires a login to use an instance which is not possible because Libre.Video has user registration disabled.
So now I’ve added Peertube 1312 to NewPipe, it appears to be following more instances and the Recently added, Local and Trending videos are all playing. I might be sorted.
I haven’t used Mastodon since creating an account years ago but it’s good to know I can go down that route as an alternative.
I added your instance in NewPipe and Trending, Recently added and Local all work fine.
