Frigate’s 0.17⇒0.18 upgrade went mostly painlessly, sans one side effect from the embedded FFMPeg upgrade from v5 to v8.

In the go2rtc config section, add:

go2rtc:
  ffmpeg:
    global: "-vaapi_device /dev/dri/renderD128"

(or whatever render device you have if not renderD128, though this is the most common)
