Real-Time Audio-Video works with standard webcam, USB audio, and analog audio devices. The feature also works with standard conferencing applications. To support Real-Time Audio-Video, your deployment must meet certain software and hardware requirements.

Remote desktops

To use more than one webcam, microphone, or speaker in a remote desktop or published application, Horizon Agent 2209 or later must be installed.

When using Microsoft Teams with Real-Time Audio-Video, remote desktops must have a minimum of 4 vCPUs and 4 GB of RAM.

Horizon Client computer or client access device
  • Real-Time Audio-Video is supported on all operating systems that run Horizon Client for Linux on x64 devices. This feature is also supported on Raspberry Pi 4 Model B devices running Stratodesk NoTouch Operating System. The client system must meet the following minimum hardware requirements.
    Resolution Frame Rate CPU Required Memory
    320 x 240 15 FPS 2 core, 1800 MHz 105 MB
    640 x 480 15 FPS 2 core, 2700 MHz 150 MB
    1280 x 720 15 FPS 4 core, 3400 MHz 210 MB
  • Horizon Client requires the following libraries:
    • Video4Linux2
    • libv4l
    • Pulse Audio

    The plug-in file (/usr/lib/pcoip/vchan_plugins/libviewMMDevRedir.so) has the following dependencies: 

    libuuid.so.1
libv4l2.so.0
libspeex.so.1
libudev0
libtheoradec.so.1
libtheoraenc.so.1
libv4lconvert.so.0
libjpeg.so.8

    All these files must be present on the client system or the Real-Time Audio-Video feature does not work. These dependencies are in addition to the dependencies required for Horizon Client itself.

  • The webcam and audio device drivers must be installed, and the webcam and audio device must be operable, on the client computer. You do not need to install the device drivers on the machine where the agent is installed.
