Configuring Real-Time Audio-Video on a Mac OS X Client
You can configure Real-Time Audio-Video settings at the command line by using the Mac OS X defaults
system. With the defaults system, you can read, write, and delete Mac OS X user defaults by using Terminal
(/Applications/Utilities/Terminal.app).
Mac OS X defaults belong to domains. Domains typically correspond to individual applications. The
domain for the Real-Time Audio-Video feature is com.vmware.rtav.
Syntax for Configuring Real-Time Audio-Video
You can use the following commands to configure the Real-Time Audio-Video feature.
Table 4‑4. Command Syntax for Real-Time Audio-Video Configuration
Command Description
defaults write com.vmware.rtav scrWCamId "webcam-
userid"
Sets the preferred webcam to use on remote desktops. When this
value is not set, the webcam is selected automatically by system
enumeration. You can specify any webcam connected to (or built
into) the client system.
defaults write com.vmware.rtav srcAudioInId "audio-
device-userid"
Sets the preferred microphone (audio-in device) to use on remote
desktops. When this value is not set, remote desktops use the
default recording device set on the client system. You can specify
any microphone connected to (or built into) the client system.
defaults write com.vmware.rtav srcWCamFrameWidth
pixels
Sets the image width. The value defaults to a hardcoded value of
320 pixels. You can change the image width to any pixel value.
defaults write com.vmware.rtav srcWCamFrameHeight
pixels
Sets the image height. The value defaults to a hardcoded value of
240 pixels. You can change the image height to any pixel value.
defaults write com.vmware.rtav srcWCamFrameRate fps
Sets the frame rate. The value defaults to 15 fps. You can change
the frame rate to any value.
defaults write com.vmware.rtav LogLevel "level"
Sets the logging level for the Real-Time Audio-Video log file
(/Library/Logs/VMware/vmware-RTAV-pid.log). You can set
the logging level to trace or debug.
defaults write com.vmware.rtav IsDisabled value
Determines whether Real-Time Audio-Video is enabled or
disabled. Real-Time Audio-Video is enabled by default. (This
value is not in effect.) To disable Real-Time Audio-Video on the
client, set the value to true.
defaults read com.vmware.rtav
Displays Real-Time Audio-Video configuration settings.
defaults delete com.vmware.rtav setting
Deletes a Real-Time Audio-Video configuration setting, for
example: defaults delete com.vmware.rtav
srcWCamFrameWidth
NOTE You can adjust frame rates from 1 fps up to a maximum of 25 fps and resolution up to a maximum of
1920x1080. A high resolution at a fast frame rate might not be supported on all devices or in all
environments.
Configure a Preferred Webcam or Microphone on a Mac OS X Client System
With the Real-Time Audio-Video feature, if you have multiple webcams or microphones on your client
system, only one webcam and one microphone can be used on your remote desktop. You specify which
webcam and microphone are preferred at the command line by using the Mac OS X defaults system.
With the Real-Time Audio-Video feature, webcams, audio input devices, and audio output devices work
without requiring USB redirection, and the amount of network bandwidth required is greatly reduced.
Analog audio input devices are also supported.
