Capturing vs passthrough recording ** Solved **

[LBDG]

** Solved ** I just solved it myself. It is under "decoding: none".

I just upgraded recently to 1.37 (from 1.36) and noticed that the camera must be capturing in order to continuously record in passthrough.

This take a lot of CPU cycles on high res.

Under 1.36, I used to continuously record the hi-res stream but I did not have live view. I do think there was a ZMC process running but I do not remember.

Is there a way to simply record in passthrough without the live view? or zmc process?

Thx

Have you tried the Decoding options on the camera Source page? See the tips (?).

Edit camera -> Source -> Decoding = "Keyframes + Ondemand"
Edit camera -> Recording -> Video Writer = "Camera Passthrough"

I recommend installing RTSPToWeb:

Very soon it will be possible to use secondary stream source for RTSPToWeb for real-time viewing

RTSPToWeb type WebRTC works quite correctly now.
I will soon create a PR for correct operation of RTSPToWeb type MSE.
RTSPToWeb type HLS works relatively correctly, but there is a large lag from real time.

This will make it possible to easily view cameras in real time at a relatively low resolution and with high resolution recording without creating additional monitors.
