if anyone is still interested, in my opinion scrypted is a much better solution. and it also has a better homekit integration and almost no delay. just add the scrypted home assistant. In scrypted add the FFmpeg, homekit and Pam diff Motion detection. to add a camera go to the FFmpeg and use this for the input
-f h264 -i https://[user name]:[password]@[camera ip]:19443/https/stream/mixed?video=h264&audio=g711&resolution=hd
notes: 1 - thanks to joshgetter for the add on, i used it for a long time
2 - if anyone knows how to add the audio to the input argument, please let me know. thx
