tiny-webrtc-gw VS libdatachannel

https://github.com/justinb01981/tiny-webrtc-gw SFU that runs on raspbian linux

_Security Camera aggregator/recorder? (SFU?)_ Are there any lightweight systems for recording the RTP streams from security cameras that play nice with webRTC? https://github.com/justinb01981/tiny-webrtc-gw (sfu) maybe fork the code and write the publisher streams to disk? it _ought_ just be a matter of hooking into the publisher -> subscriber(s) streaming code and writing raw RTP or maybe just the RTP data into two files (video SSRC, audio SSRC)?

I use a really lightweight (I run mine on a raspberry Pi4) conferencing SFU as the basis for a video-chatroom. https://github.com/justinb01981/tiny-webrtc-gw

ooh! I think I can help with this: https://github.com/justinb01981/tiny-webrtc-gw

You're describing an "SFU" https://webrtcglossary.com/sfu/#:~:text=SFU%20stands%20for%20Selective%20Forwarding,and%20not%20a%20specific%20device. I think. I tried my hand at writing an all-in-one webserver that handled the STUN and the multiplexing (https://github.com/justinb01981/tiny-webrtc-gw)

You can use https://github.com/paullouisageneau/libdatachannel for your C/C++ integration needs. It's 10k lines. So the answer is 0. Its required dependencies (I assume this as they are git submodules in deps) are more than 100k lines, though, srtp support making the bulk of it. On my machine it took 11 seconds to compile it.

Irssi is 64k lines (plus its dependencies), so I guess that makes WebRTC complicated.

Can't argue that DCC isn't simple, but perhaps the protocol deviced decades ago is a bit too simple.

Most of the work happened in the libdatachannel! You can check out my PR here[0]

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!

This is not true, there are actually multiple WebRTC implementations in different languages besides the reference library: aiortc (python), libdatachannel (C++), sipsorcery (C#),webrtc-rs (rust), werift (Typescript), and Amazon Kinesis (C)

Use any means necessary to transfer your data across devices. Could be IPFS, could be FTP, could be EventSource, WebSocket, WebTransport, Fetch, whatever. See https://github.com/guest271314/secure-file-transfer; offscreen-webrtc, https://github.com/paullouisageneau/libdatachannel.

I've successfully used libdatachannel to Web pages to connect native applications and stream data to the browser.

Alternatively you can use your server as a signaling server for WebRTC (Insertable Streams ("Breakout Box"), or data channels https://github.com/paullouisageneau/libdatachannel), then users (peers) can exchange data themselves and you don't need to store anything, see True End-to-End Encryption with WebRTC Insertable Streams, A complete example for a WebRTC datachannel with manual signaling.

there is also a c++ library that can be used to open a data channel connection, I think a number of SFU “servers?” use this library (I wish I had) https://libdatachannel.org/

For networking and terminating WebRTC connections from cpp libdatachannel is you easiest bet. For transcoding you can pick whatever library you like, if any. The other way would be to use the chrome WebRTC stack and modify it for server use. It can and has been done but is very involved.
