When camera is not connected and I start mtplvcap it is exiting, but if I just disconnect the camera while capturing it continue and just sending errors continuously:

I'm planning a huge improvement including this issue after I find the time. I'm now super busy so it'll be in October or November. Thank you.

I am using it in systemd unit that is started automatically by udev when camera is connected. I can share them if you are interested, but without this enhancement it will work only first time, then you need to kill it manually...
