Unable to start RTSP server

I just received my xiaofang today and tried the hack. But I was unable to get RTSP working. I'm able to access the status page, applied the hack and reboot.

In the "Manage scripts" page, "02-rtsp-server" does not have a status and clicking run does nothing. "03-rtsp-server" has NOK status and clicking "start" does not work either.

I then telnet into the device, enabled logging and this is what I see:

/media/mmcblk0p2/data/etc/scripts # cat /tmp/rtsp_server.log 
Video source = /dev/video1 
Cannot open '/dev/video0': 16, Device or resource busy

I'm not sure which other process is using /dev/video*

Can someone please help me with this?

fwiw, this is my process list:
