Subject: Video4Linux Control Panel Preview uses wrong device
Date: Sat, 16 Oct 2010 22:28:50 -0700 [thread overview]
Message-ID: <4CBA8992.1010504@comcast.net> (raw)
I have two video devices in my system. Usually they are:
/dev/video0 A Microsoft LifeCam Cinema
/dev/video1 An ATI HDTV Wonder
but sometimes the devices get swapped.
I have been trying to debug the ATI HDTV Wonder, but ran into a problem with the Video4Linux Control Panel.
No mater how I start v4l2ucp such that it is displaying & editing /dev/video1, when I select preview, it selects /dev/video0
instead. I know that it is selecting /dev/video1 because I am trying to preview the ATI HDTV Wonder, but the blue LED on the web
cam comes on, and I get audio feedback from the microphone on the camera through my speakers.
I will be happy to provide more information if you will tell me what information you need (and how to get it, as my experience
with linux is limited.)
v4l2ucp Version 2.0.2
