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.

About this task

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 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 7 or Windows 8


    The format of the log file is debug-20YY-MM-DD-XXXXXX.txt , where 20YY 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#

  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.
