Simple post to solve a little/big issue: i was playing with HASSIO and my ipcameras ( chinese nobrand 🙁 ) and i have a problem when i was using ffmpeg: even with a single ipcamera, i had 100% cpu usage. It was a nightmare!
Until i found mjpeg: infact, replacing ffmpeg with mjpeg i’ve dropped the cpu usage to near 0% in this way:
camera: - platform: ffmpeg input: rtsp://admin:firstname.lastname@example.org:10554/udp/av0_0
camera: - platform: mjpeg mjpeg_url: "http://192.168.0.36:38736/snapshot.cgi?user=admin&pwd=xxxxx"
Of course you need a ipcamera that supports CGI.
You can simple discover open ports on your IPCamera with nmap in this way:
nmap - 1-65535 $youripcamera
