the command line hang here, you cannot kill it because it enters uninterruptible sleep status, if you view it by "ps -aux|grep mjpg", you will see D+

What hardware/OS/camera is this running on? Can other software (e.g. ffmpeg) capture from the camera successfully?

Hardware: Orange Pi PC Software: 5.4.65-sunxi #2.0.8 SMP (Bionic) Camera: a cheap USB Camera, no branding.

ffmpeg works, now I switch to motion, which also works fine.
