Is it possible to use the rpiCamera source "on demand"?

Question

Hi everyone,

Firstly, thanks for all the work on MediaMTX and especially for adding native camera support for Raspberry Pis.

The rpiCamera source works really well, but I notice that it's using the camera and encoding frames all the time, even when nothing is requesting the stream.

By contrast, if I encode the camera stream myself in order to publish it to MediaMTX using RTSP, then I can use runOnDemand to start the script which opens the camera and publishes that RTSP stream.

So I'm wondering if there's any way to arrange for the rpiCamera source to start capturing and encoding images only when the stream is requested. As far as I could tell from the README page, I couldn't see that this was possible.

Thanks in advance for any help!

It's perfectly possible by using sourceOnDemand:

paths:
  rpi:
    source: rpiCamera
    sourceOnDemand: true

Ah, thank you very much. I should have spotted that in the mediamtx.yml file!
