Testing a Webcam Using YouCam

  • PrintPrint
This document pertains to HP Notebook PCs with Windows Vista or Windows 7.
Most webcam problems are caused by missing or incompatible hardware drivers, or by incorrectly configured video display applications. This document will help you test the basic functionality of the webcam using a known good webcam hardware driver, and a simple video display application. Once you have determined that the webcam works, you can adjust the quality of the image or use a more sophisticated application to manipulate the image.

Opening YouCam

To test the webcam with Cyberlink YouCam, click Start , type youcam in the Search field, and select YouCam from the list.
If YouCam does not appear in the list of search results, go to Installing the YouCam Application for instructions on installing the YouCam application. Otherwise, continue following the instructions below.
When the application opens, assuming the area in front of the webcam is brightly lit, you will see an image of yourself displayed in the center of the application.

If the YouCam application opens and you see your image displayed in the center of the application, go to Capturing and playing a video image to continue testing. Otherwise, read a section below that matches your error and follow the instructions to correct the error.

Error message displays when opening

The YouCam application may not open or may display an error message similar to the following:
Cannot connect to this video device (USB Video Device).
Please select another capture device via Settings or close any application that may be using this video device and restart YouCam.
Follow the steps below to resolve the webcam display problem.
  1. Exit any secondary video application
    The webcam driver can only be used by one program at a time. For example, you cannot open and use YouCam while doing a video conference with an instant messaging program.
    If there are any other video programs open on your computer, close them, and then go to Opening YouCam to continue testing. Otherwise, continue with the next step.
  2. Verify the webcam hardware is recognized in Device Manager
    1. Click Start , enter device manager in the Search field, and select Device Manager from the list.
    2. In the Device Manager window, find the Imaging Devices category.
      If a webcam or video device driver is listed in the Imaging Device category, go to, Selectively update the webcam driver .
      If there is no Imaging Devices category, click Action , and then select Scan for hardware changes to scan for the webcam video display device.
      If no Imaging Device entry displays in Device Manager after running the scan, there is a hardware issue. Contact HP Support for technical assistance.
  3. Selectively update the webcam driver
    1. In Device Manager , expand the list of Imaging Devices , right-click the webcam driver, and then select Properties .
    2. In the Webcam Properties dialog box, select the Driver tab, and then click the Update Driver... button.
    3. In the Update Driver Software window, select Browse my computer for driver software , and then, when prompted, select Let me pick from a list of devices on my computer .
    4. When prompted, in the Model section, select USB Video Device , and then click Next to update the webcam driver software.
    5. After the message, Windows has successfully updated your driver software , click the Close button, close all open dialog boxes, and then go to Opening YouCam to continue testing.

No image displays on application window

If the YouCam program opens, but displays an image of the application's name rather than your image, there is an incompatible driver selected by default. Follow the steps below to resolve this webcam display problem.
