    I originally went the same route as you, and found that is probably the best package out there for webrtc. I learned go just for it, and it paid off tenfold. Less memory, more connections, lower latency.
  • WebRTC 102: Understanding libWebrtc
    4 projects | | 27 Nov 2022
    The "Mediasoup" project provides a high level JavaScript/TypeScript interface to the WebRTC APIs. The core logic of this project is implemented in C++/Rust. Consider taking a look at the project if you want an easy-to-use library instead of the low-level libWebRTC APIs. A notable project to mention is the Pion/webrtc project which has a Golang implementation of the WebRTC API. Of course, we should mention the rust port Let’s keep all the rustaceans happy too!
  • Ask HN: FFmpeg real-time desktop streaming

    What latency are you trying to do? Will the professor being communicating with the students while doing this? Will the students all have the same bandwidth, or will you want multiple renditions (low, med, high quality levels)?

    If you want AV1 you will not be able to use RTMP. The protocol is orphaned/deprecated, so avoid if possible!

    If I was building it this is what I would do, and my reasoning.

    * For capture + encoding I would use OBS. You will want to use something that is easy for users to install configure. Professors will also have lots of custom requirements when it comes to layout etc... it will be tempting to do a ffmpeg command directly, but it will fall apart quick I believe.

    * To get AV1 out of OBS I would use FFMPEG output. I would have it send RTP. RTP is used to carry video in a sub-second manner. This is the same protocol that WebRTC uses. You know have AV1 + low latency.

    * Then for users to watch I would use WebRTC. That will allow them to watch in their web browser. Conceptually it will be like this this takes the RTP packets and puts them in the browser.

    Lots of great projects exist that you could use for 'RTP -> WebRTC' like and I would suggest checking them all out!

    If you have more questions/want to talk to people in the video space always happy to chat on :)

    For streaming video content your options would be HLS or WebRTC, maybe look into these gwuhaolin/livego and pion/webrtc.

    Do you still see challenges with doing WebRTC on a server? I work on so would love to hear what could be better :)

    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 (, 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 (, and I've been actively participating in the Pion community ( and collaborating with the authors of ion-sfu ( and LiveKit (
