Have a working PoC of this so I thought I’d share: GitHub - roger-/blinkbridge: Blink camera -> RTSP bridge
It’s a Docker-ized app to publish Blink motion clips to RTSP. There’s currently about a ~30s delay and the video will be static until motion is detected, but it’ll let you use Frigate, etc. with your Blink cameras.
Eventually I’ll try to integrate an ONVIF server with motion events so it can be used with Scrypted for HSV support.
