Frigate w/TPU, high cpu usage

Third party integrations
1

Using Frigate with a pcie Coral. I had it doing 4 cameras but cpu was pegged. Just doing 1 1080p camera it sits at 30% cpu usage. Does that seem right?

   ...done.

Frigate uses the CPU until something is detected and it’s at that point it’s passed to the Coral for analysis

Try switching to a sub stream to use less CPU

OK, thanks, I wasn’t aware it worked like that
