Troubleshooting
No video image
If you have no video display (a black video window):
•
Select the right video input. Use Configure to see all three video
inputs. Make sure PAL is selected (for Europe).
•
No video in NetMeeting: you installed NetMeeting before installing
the Videum software. Uninstall NetMeeting, delete the NetMeeting
directory, reboot, and reinstall NetMeeting.
Scrambled video
If your video display is scrambled or the Video Control Panel shows
video but not your application:
•
Verify the NTSC/PAL setting (in Europe: select PAL)
•
Verify that the video format is compatible with your application.
•
Try uncompressed capture (YUY2 or RGBT)
Speckled or grainy video
Your display is set to 256 colors or less. Set it to 16-bit or better 24-bit
color.
No audio
Multiple sound cards are supported in parallel. The Videum AV and the
VideumCam AV integrate an audio in and out device, a second sound
card in addition to the sound card, which may already be installed.
•
Use the Multimedia control panel to select the sound device for
recording and playback.
•
Open Audio Panel from the Videum menu to select the audio input
and output of the Videum board. Make sure the audio output is not
muted.
Black bars around video in MS NetMeeting
MS Netmeeting may show black bars around the video (in the “large”
mode). Please make the following change to the registry:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Conferencing\CaptureDevices\
”driver name”]
„dwImageSize“ = 40,04,00,02 (hex)
