With the Real-Time Audio-Video feature, you can use the local client system's webcam or microphone in a remote desktop or published application. Real-Time Audio-Video is compatible with standard conferencing applications and browser-based video applications. It supports standard webcams, audio USB devices, and analog audio input.

Starting from the Horizon 8 2212 release, Horizon Client for Windows uses Windows Audio Session (WASAPI) API as the audio-in API by default instead of Wavein. To use Wavein as the audio-in API, disable WASAPI from the client registry, set the DWORD registry key named EnableAInWasapi under Computer\HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\RTAV to 0 and re-connect your session.
Note: For the Real-Time Audio-Video feature in nested mode, using WASAPI when RTAV is not running in bypass mode may result in low audio quality. To avoid this issue, you should disable WASAPI on the second-hop client. RTAV is in bypass mode in the following cases:
  • C1, A1, C2, A2 are on Horizon 8 2209 or later release
  • C1, A1, C2, A2 Horizon 8 2206 or earlier release
Nested RTAV is not in bypass mode for cases other than those described above.
To use hardware accelerate registry keys for Windows, perform the following steps:
  1. Open the regedit.exe file located at HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\RTAV.
  2. Set the following options as appropriate:
    • forceNV = 1 to enable NVIDIA hardware acceleration
    • forceQSV = 1 to enable Intel Quick Sync Video hardware acceleration

Real-Time Audio-Video hardware acceleration works on your client only if the Graphics processing unit is supported on your computer and is compatible with FFmpeg.

For information about setting up the Real-Time Audio-Video feature on the agent machine, including configuring the frame rate and image resolution, see the Horizon Remote Desktop Features and GPOs document.
