I have cameras that are smart and have sensors and some computer vision built into them (eg. lux, audio detection, people counting, etc). Everything works great, but for whatever reason, I can’t use it with an RTSP url like the other camera integrations!
I would add, that it would be awesome to be able to supply HA with an RTSP url over MQTT instead of having to statically define each camera in a yaml file. This would enable the MQTT camera integration to offload the video streaming from MQTT as a binary file to an ffmpeg camera stream.
