With the Real-Time Audio-Video feature, if you have multiple webcams on your client system, only one of them is used on your View desktop. To specify which webcam is preferred, you can set a registry key value.

The preferred webcam is used on the remote desktop if it is available, and if not, another webcam is used.


  • Verify that you have a USB webcam installed and operational on your client system.
  • Verify that you are using the VMware Blast display protocol or the PCoIP display protocol for your remote desktop.


  1. Attach the webcam you want to use.
  2. Start a call and then stop a call.
    This process creates a log file.
  3. Open the debug log file with a text editor.
    Operating System Log File Location
    Windows XP C:\Documents and Settings\username\Local Settings\Application Data\VMware\VDM\Logs\debug-20YY-MM-DD-XXXXXX.txt
    Windows 7 or Windows 8 C:\Users\%username%\AppData\Local\VMware\VDM\Logs\debug-20YY-MM-DD-XXXXXX.txt
    The format of the log file is debug-20YY-MM-DD-XXXXXX.txt , where 20 YY is the year, MM is the month, DD is the day, and XXXXXX is a number.
  4. Search the log file for [ViewMMDevRedir] VideoInputBase::LogDevEnum to find the log file entries that reference the attached webcams.
    Here is an excerpt from the log file identifying the Microsoft Lifecam HD-5000 webcam:
    [ViewMMDevRedir] VideoInputBase::LogDevEnum - 2 Device(s) found
    [ViewMMDevRedir] VideoInputBase::LogDevEnum - Index=0 Name=Integrated Webcam   UserId=vid_1bcf&pid_2b83&mi_00#7&1b2e878b&0&0000   SystemId=\\?\usb#vid_1bcf&pid_2b83&mi_00#
    [ViewMMDevRedir] VideoInputBase::LogDevEnum - Index=1 Name=Microsoft LifeCam HD-5000  UserId=vid_045e&pid_076d&mi_00#8&11811f49&0&0000  SystemId=\\?\usb#vid_045e&pid_076d&mi_00#
  5. Copy the user ID of the preferred webcam.
    For example, copy vid_045e&pid_076d&mi_00#8&11811f49&0&0000 to set the Microsoft LifeCam HD-5000 as the default webcam.
  6. Start the Registry Editor (regedit.exe) and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\RTAV.
  7. Paste the ID portion of the string into the REG_SZ value, srcWCamId.
    For example, paste vid_045e&pid_076d&mi_00#8&11811f49&0&0000 into srcWCamId.
  8. Save your changes and exit the registry.
  9. Start a new call.
