frigate on coral devboard and minidevboard

[saket424]

Has anyone got frigate to work on either the coral devboard or the coral mini devboard running mendel ?
I just got this board and got docker working with it and now want to attempt to use frigate

@blakeblackshear what do i use for the detectors section ?
it is neither a pci nor a usb device so i am stuck. the parrot inference sample in the get-started section works fine

Did you try using pci:0? I think its using the same module, so that might work. If not, I would ask them what you would use for the dev mini for the device name as shown here: https://coral.ai/docs/edgetpu/multiple-edgetpu/#using-the-tensorflow-lite-python-api

Per your suggestion, I just now tried pci:0. No dice

I tried usb:0 instead and it appears to have worked. but now i am getting some complaints from ffmpeg

I could have sworn that lsusb output wasnt Google earlier but now it is

The ffmpeg noise was relating to the hwaccel_flags. For the momemnt, I have commented it out.
I have frigate working now on the coral mini devboard. @blakeblackshear , any recommendations on what the
right hwaccel_flags showuld be?

It is a usb device. frigate worked with detector set as usb and TPU was found.
