[Config Support]: Disable everything but simply continuously recording to files

[RobHofmann]

Describe the problem you are having

I'm trying to disable all detect/motion/snapshot recording features and just enable continuously record. I still see 2 cores being fully used (200% CPU on Linux) while recording. Is this normal?

Any other information that may be helpful

Running on a Ryzen 3900X with TrueNAS inside a Ubuntu host with Docker.

There's no way to disable the decoding of the stream for the live view / motion detection (which can be used to only keep recording when the camera sees motion).

If you enable hwaccel then that will reduce the CPU usage

[NickM-27]

Also recommend updating to 0.11 using image blakeblackshear/frigate:stable

Is there any HWaccel available for a Ryzen 3900X? (again i'm using TrueNAS with a Ubuntu VM which runs Docker; and thats where Frigate runs).

I switched to blakeblackshear/frigate:stable. However I now no longer have a live view (more like a 5 fps feed in Home Assistant). This isn't fixed whenever I switch back to blakeblackshear/frigate:stable-amd64. Also not when doing a clean install.

[NickM-27]

No that CPU has no integrated GPU so it can't do hardware acceleration.

And also you disabled RTMP so of course the home assistant live view isn't full res / speed, that is what RTMP is used for.

[RobHofmann]

Doh! you are completely right! Sorry about that!

So about 3 cores in use for 6 camera's seems fair? It can't go any lower?

Is using an Intel CPU (for example the 12500T) more efficient in terms of power for these tasks?

[NickM-27]

It doesn't have much to do with intel or AMD. For example I have an AMD 5700G which does hardware acceleration (since it has integration RDNA graphics) and that means with 4 cameras frigate only uses 5% CPU (with a coral and detection enabled).

[NickM-27]

Another thing that would help you is setting the width and height if the cameras under detect, otherwise frigate resizes it to 720p which also uses considerable CPU

[NickM-27]

I'd recommend just checking out #3860 actually as it covers your case as well

[RobHofmann]

Perfect! Modifying the detection resolution & fps got my CPU usage down to ~200%. Thats fair i think.

Thank you for all the information!

I'll see to upgrade my CPU to something with an iGPU & try to hunt a Coral unit.
