Pion WebRTC VS galene

I am really excited about https://github.com/sepfy/libpeer. It has examples ready for ESP32 etc....

When working on KVS I wasn't familiar with the embedded space at all. I saw 'heavyweight' embedded where you were running on Linux. Then you had RTOS/No OS at all. I wasn't prepared for these devices at all. If we can make WebRTC work in the embedded space I think it will really accelerate what developers are able to build!

Remotely driven cars, security cameras, robots in hospitals that bring iPads to infectious patients etc... Creative people are building amazing things. The WebRTC/video space needs to work harder and support them :)

I love how diverse the WebRTC space is now. Outside of this implementation you have plenty of other options!

* GStreamer’s webrtcbin (C)

See https://github.com/sipsorcery/webrtc-echoes for examples of some running against each other.

I have worked four jobs related to https://github.com/pion/webrtc and one for https://webrtcforthecurious.com

Two companies used Pion. The other two were just using the protocol (WebRTC)

In my experience Go has been relatively approachable for people that are good at PHP. It has a great standard library and a pretty solid ecosystem, though frameworks aren’t as popular in Go. There are some well regarded libraries for things like WebRTC via https://github.com/pion/webrtc WebSicket via https://github.com/nhooyr/websocket

Don't try to make RTC yourself, it looks easy, but in fact, it's a really hard problem to solve. Use https://pion.ly/ it's a pretty solid package they also have a discord/slack channel with a lot of helpful people there.

Maybe you can reuse some of this code: https://github.com/pion/webrtc/blob/master/examples/data-channels/main.go

I would like to recommend Galene: https://github.com/jech/galene

Runs in my raspberry pi, a single small executable, like in the old good times.

> Do you happen to know of others by any chance.

There's Galene, <https://galene.org>. It's easy to deploy, uses minimal server resources, and the server is pretty solid. The client interface is still a little awkward, though. (Full disclosure, I'm the main author.)

galene - basically selfhosted zoom/jitsi

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 https://github.com/pion/webrtc/tree/master/examples/rtp-to-w... this takes the RTP packets and puts them in the browser.

Lots of great projects exist that you could use for 'RTP -> WebRTC' like https://galene.org/ and https://livekit.io/ 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 https://pion.ly/slack :)

galene

The most lightweight all-inclusive central solution for video conferences I know is Galene. It runs in under 200 MB RAM.

Even though the default UI is extremely simplistic, I very much like galene. It bundles all the components you need in a single binary. Even a TURN server so you don't have to fiddle with coturn. Not to mention that it's very resource efficient.
