I am currently running 1.22.2. We have a HD15/DVI Frame Grabber installed and would like to capture with ZoneMinder. Frame Grabber is seen via V4L and works with XAWTV. v4lctl -d /dev/video0 list works and shows all the options for image control.

When I run:
There is no Physical BNC interface on the cards so it mybe part of the board just not attached.

Code: Select all

v4lctl -d /dev/video0 list

Code: Select all

  #zmu -q -d /dev/video0
  #error22

When I add the -v switch I get:

Code: Select all

  #zmu -q -v -d /dev/video0
  #Error: Failed to get video capablities /dev/video0: Invalid Argument

So do the additional arguments need to be added to just the database or would I also have to modify the source?
