High CPU, HW accel not working?

[bruceda-nz]

Hi all

I have Viseron up and running on an old Ubuntu machine but I am struggling with really high CPU use. The machine has an i5-3470 which should support QSV and definitely supports VAAPI.

I am exposing /dev/dri in my docker-compose file

when I bring the container up, it runs but I get an error libva: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so init failed

If I execute vainfo in the container it says similar about iHD and then seems to fall back to i965 and then work.

I have one camera running currently for testing and even if I use the low res substream, when I run top in the host OS it shows python consuming 300+% CPU time. The same thing happens regardless of stream.

intel_gpu_top in the host OS shows activity but it's the CPU usage that has me puzzled.

I have set the detector to motion only to see if it creates peaks but once the stream starts the CPU goes high.

I know the CPU is old and not that capable but I thought with a 640x480 substream at 5fps I'd be ok.

Any ideas of where to start looking?

If you run top -c inside the container, what is the command behind the process that is taking all the CPU?

[bruceda-nz]

viseron -u -m viseron

Is that what you were expecting?

Strange that the Viseron process is using so much CPU. It only runs image decoding and optionally motion detection which shouldnt be that demanding.

Can you show me your config?

I have just sorted it out now.

Entirely my own fault, I had object detection on and set to detect on motion but then no motion detection enabled.

Great!

Bump

@roflcoopter any thoughts on this?
