rtsp-server.py cause raspberry 3B+ in low power status, and raspberry power led will not show red light about rpanion-server

Are you using a USB video device?

The Pi is having to compress the video stream from RAW to H264 in realtime, which does take a lot of CPU. So 170% is expected.

If you're having power issues, find a better power supply. Some power supplies are unable to cope with the Pi at higher cpu usages.

Otherwise, check if your video device can support H264 output, so the Pi doesn't have to compress the video. Or go with a lower resolution.

Yes, USB camera format: x-raw.
PI3B+ power 5V 2.5A, it enough.
go with a lower resolution: python3 Rpanion-server/python/rtsp-server.py --fps 5 --bitrate 200, CPU usage reduce to 30%, but poor video effect.

What camera model are you using?

Open a terminal in the Rpanion-server folder and run ./python/gstcaps.py, then post the output here. This will tell us the capabilitites of the camera

Hi Stephendade
I got it:

Ok, try running the camera at a lower resolution (320x240) and see if it's more reliable.

Keep the bitrate to at least 1000, to make it easier for the Pi to compress the video

OK, Thanks for your suggestions, I have to use the camera support H264
