userscript-youtube-playlist-o VS Pion WebRTC

A silly userscript [1] that uses jQuery selectors to interact with YouTube's DOM to help me move videos around my playlists. Sadly it breaks every few months whenever YouTube updates their DOM. AFIK this is the only way to "programmatically" move videos out of my Watch Later list since they removed the functionality from the API

I've created a couple of userscripts (anybody remember Greasemonkey?) to help augment sites that I use everyday

Sadly they break every couple of months when the sites' DOM changes. The YouTube one is currently broken and I haven't had the time to fix it yet

There's nothing particularly difficult on the server side — a quality SFU should be capable to handle on the order of 400 video flows per core, and there are quite a few high-quality free software SFUs available (Janus, Jitsi, ion-sfu, livekit, Galene). To give some perspective: we're using Galene for lectures, and our single-CPU server uses around 40% CPU usage in a room with 120 students (who keep their cameras switched off during the lecture, of course, and only occasionally switch them on to ask questions).

As the grandparent mentioned, the problem is the client side. Since there is no standard videoconferencing protocol, every free software project needs to develop their own clients. And it's difficult for a free software project to have the manpower and expertise to develop quality clients for the web, Android and iOS, so in effect what we currently have are mostly half-baked web clients.

There is some hope, though. The IETF have been working on standard protocols for ingress (https://datatracker.ietf.org/wg/wish/), and if their protocols get deployed, you'll be able to use the same streaming software (think OBS) or IP camera with multiple distinct videoconferencing servers. An interoperable interactive videoconferencing protocol is nowhere near, but as more people understand videoconferencing technology, there is some hope that people will get together and start working on multi-protocol clients (remember Pidgin?).

Full disclosure: I'm the author of Galene (https://galene.org), and I've been actively participating in the Pion community (https://github.com/pion/webrtc) and collaborating with the authors of ion-sfu (https://github.com/pion/ion-sfu) and LiveKit (https://github.com/livekit).

Thanks! Its using the Pion library[1] which doesn't seem to be using a constant bitrate; that would definitely be an interesting addition though. Sending e.g. zeroes when its not transmitting packets/frames is totally doable, but atm not implemented.

The idea was to port Pion, the web RTC library in Go to Rust, and I played a major role in the early days of the project. I was involved in the RTP library, SRTP, and the Multicast DNS. I put in a lot of time, a commodity the strike ensured I had a lot of, and we made a lot of progress. In fact, a lot of people rallied behind the project making it worthy of the title Open source. It currently has almost 2000 stars on Github.

If you want to deal with NAT traversal I recommend doing this with WebRTC ... The pion project is perfect for this.
