    Frigate Test Clip

To tune Frigate, it can sometimes be useful to input saved clips in order to see how detection works. I've found the easiest way to accomplish this is by grabbing a clip (say, from your NVR), and streaming this on a loop via RTSP to Frigate. This will let you tune settings with an existing configuration, which is a bit different to using process_clip.py that's included with Frigate.
Pre-requisites


A sample clip, in a format supported by ffmpeg (.mp4 is good)
Docker on a machine that'll do the streaming
A working ffmpeg install. I'm using a mac, so I typically install via Brew: brew install ffmpeg

Stream a clip

To stream a file called trimmed.mp4:

Setup an RTSP server - run docker run --rm -it -e RTSP_PROTOCOLS=tcp -p 8888:8554 aler9/rtsp-simple-server
Stream the file: ffmpeg -re -stream_loop -1 -i trimmed.mp4 -an -c copy -f rtsp rtsp://localhost:8888/mystream
Update Frigate's config.yml to add a new test camera to point at our looping clip (assuming 192.168.1.180 is the host running the RTSP server):
cameras:
  testcamera:
    ffmpeg:
      input: rtsp://192.168.1.180:8888/mystream
