v4l2rtspserver VS obs-rtspserver

If you want to stream your webcam as an H264 encoded rtsp stream, it can be done with either rtsp-simple-server or V4l2rtspserver And it is possible to stream a linux desktop (and any program that might be open, like your web browser with the gcode viewer running on it) with the V4l2Loopback device and either of the two prgrams above. It is quite an involved process, but it is do-able.

v4l2rtspserver is about the only thing I've found for running a raspberry pi with the internal cable camera

Then get the OBS rtsp plugin on github (https://github.com/iamscottxu/obs-rtspserver/releases) and install this too. You can access it through the tools tab in UBS and configure it to send out the OBS picture through an rtsp stream.

I haven’t done it but all you should need to do is setup OBS to stream to a RTSP and tweak OctoPrint to see it.

Ah. Well, there's this version luckily: https://github.com/iamscottxu/obs-rtspserver/releases/tag/v3.0.0-beta3

Also, an alternative that might be useful if you do want to watch some sort of video (or if Krfb likes to crash after a while) is to use OBS to create a virtual screen and adding the RTSP server plugin to it, you can then use VLC to connect to the stream, although there will likely be a significant amount of latency (1-2 seconds in my case) with that option.

just found out about this, something like this is probably what you'd be looking for https://obsproject.com/forum/resources/obs-rtspserver.1037/

Alternately it looks like there's a plugin for OBS to publish rtsp streams. It's overkill but would work.

I have a project where I need to stream gameplay from several computers to a couple of Yodecks, which are basically just digital signage Raspberry Pi's. The Yodeck software uses Streamlink as it's backend for streaming video. Everything is on the same local network. I've tried using the RTSP server plugin, and while it technically works, the quality is terrible and it freezes constantly. Streaming from OBS to Twitch, and then having the Yodeck grab the Twitch stream works with only a few seconds lag (acceptable), but I'd prefer not to have the video leave the network since I'm not sure how good our actual bandwidth will be on site during the event.
