There is also “Owncast”, but it seems to suffer from the same issue that peertube does; there is no integrated revenue system for the streamer, so there is little reason to put effort in to the quality, as well as it being fairly unknown, so even if you set up donos etc. the audience isn’t there.
The discoverability don’t help, since there isn’t really s good way to filter out all the “24/7 radio” -streams, so even if you actively follow the frontpage, or a category, you have to skim trough them manually. Also, there is no proper language filter (at least if you don’t have an account), and it seems it’s more popular with non-english speaking streamers.
I would so much like to love peertube, but I have yet to find any instance that hosts the trash reevant to my interests. Mostly they either are filled with reuploads from YouTube, or are full of radicalized conspiracy theories (which I encounter very rarely on any other form of fediverse).
And then there is the “dumploads”, which makes the instances seem like they only have one active contributor, as they dump like 60 videos right after another, resulting the frontpages to have just one note content. This, however, could be gixed by otion to group conecutive uploads as “[latest video] and [n] other videos from [user]”, which would help to find more diverse content, as well as discourage dumping.
Then again, that is only my opinion, and if PeerTube is fine for others, who am I to complain. It just doesn’t seem to be for me :/
