Ghost ffmpeg-Process

[cavernerg]

I have a weird issue with my USB-Cam-Setup.

This is my config:

streams:
  MK4SESP: http://192.168.2.29:81/cam.mjpeg
  MK4SASeite: ffmpeg:device?video=/dev/video2&input_format=mjpeg&video_size=1600x896
  MK4SHinten: ffmpeg:device?video=/dev/video0&input_format=mjpeg&video_size=1280x720
  MK3SESP: http://192.168.2.80:81/cam.mjpeg

USB-Cam Config ist copy&paste from the "Add"-Page. When I start the server, everything is fine. BUT after some time, a ffmpeg process (Output from ps auxww: "ffmpeg -hide_banner -v error -f v4l2 -video_size 1600x896 -input_format mjpeg -i /dev/video2 -c copy -f mjpeg -") starts and uses 100 % CPU.

I installed go2rtc 2 times. One just through tteck proxmox lxc and the other on my own. Both have the same issue. After a restart, I can use the stream from the cam perfectly fine. As soon as this process is there, go2rtc has no access to the device. When the ghost-process is running and I stop the go2rtc-Service, the process goes down. The Ghost-process starts without any interaction after some time. Even if I don't use any of the streams. go2rtc-Log has no enlightening infos.

any hints for me?
