There is even an integration example in the ustream repo :)

Well,

I dont know when it will happen, but I plan to use a new backend in the future.
That will have more then a janus webrtc server ;)

Closing that for now, stay tuned.

just wanted to show a little love for this request. just realized the used c920 i bought avoided the h.264 purge (maybe?) and really would love a framerate higher than a constant... 2-4fps... even if its just 8, or even 6. or 5.

Does this work now with the new backend?

[meteyou]

not really... we tested https://github.com/ayufan/camera-streamer but it doesn't work really stable (mainsail PR for the client: mainsail-crew/mainsail#1275). we also implemented a HLS client for the RTSP mode in crowsnest. this works fine, but it has a really long delay (too long for my taste)

Maybe try using the stuff that PiKVM built. I believe all his stuff is customized for low latency feeds.

@NonaSuomy i tested this one from PiKVM: https://github.com/pikvm/ustreamer/blob/master/docs/h264.md

But it looks like this kills the snapshot URL. We need a solution to have a low-latency stream + snapshots for timelapse.

[NonaSuomy]

Can you verbosely explain how you tested it? If so then I will set it up the same then ask him for assistance on how to restore a snapshot url as well?

I also require the snapshot url to work for the purpose of QRCode scanning.

I followed the guide from pikvm and then started the webcam with it...

I think we could close this for now since the newly added backend "camera-streamer" has inbuilt webrtc and there for h264 support at least on Pis with "bullseye" distros ...
