I installed Frigate on Home Assistant Blue and have two cameras working. I have a Coral TPU plugged into a USB3 port and is seems to be working.

I am unable to find the proper value for hwaccel_args. If I leave out the ffmpeg key altogether, everything works but I get a warning about not having a GPU.
WARNING : Did not detect hwaccel, using a GPU for accelerated video decoding is highly recommended.
This clip from the log shows the warning and the message that the TPU was found.

Any help getting the TPU working would be appreciated.
Thanks in advance.
