Notes:

• The IP address can be the cameras themselves, or the NVR.
  • You can specify different cameras from the NVR IP by incrementing the channel number.
• Adding the -rtsp_transport tcp option greatly improved the video performance and quality for me.
  • Without it, stream would take a long time to load, stutter frequently, and would often be covered in streaks and artifacts.
  • Anyone looking to improve the output of similar IP cameras should also look at ffmpeg's RTSP-specific options
• I found that the quality of the stream would suffer when multiple devices were streaming straight from the cameras/NVR, so I've set up an RTSP proxy on the same machine running homebridge-camera-ffmpeg
• I'm running homebridge-camera-ffmpeg and its own instance of homebridge in a docker container using the marcoraddatz/homebridge image.
  • This required installing ffmpeg from the jessie-backports apt source inside the container.
