System Requirements for HTML5 Multimedia Redirection

Horizon Agent and Horizon Client, and the remote desktops and client systems on which you install the agent and client software, must meet certain requirements to support the HTML5 Multimedia Redirection feature.

With HTML5 Multimedia Redirection, if an end user uses the Google Chrome or Microsoft Edge browser in a remote desktop, HTML5 multimedia content is sent to the client system. The client system plays the multimedia content, which reduces the load on the ESXi host, and the end user has a better audio and video experience.

Remote desktop

• Horizon Agent must be installed on the virtual desktop or RDS host for published desktops. HTML5 Multimedia Redirection is installed with Horizon Agent by default. For more information, see the topics about installing Horizon Agent in the Windows Desktops and Applications in Horizon document.
• The HTML5 Multimedia Redirection group policy settings must be configured on the Active Directory server. See the topics about configuring HTML5 Multimedia Redirection in the Horizon Remote Desktop Features and GPOs document.
• The Google Chrome, Microsoft Edge, or Microsoft Edge (Chromium) browser must be installed.
• The VMware Horizon HTML5 Multimedia Redirection extension must be installed in the browser. See the topics about configuring HTML5 Multimedia Redirection in the Horizon Remote Desktop Features and GPOs document.

Client system

• Client systems running RHEL 7.9 are not supported.
• The HTML5 Multimedia Redirection Support custom setup option must be selected when you install Horizon Client. This option is selected by default.
• GNU C Library (glibc) version 2.14 or later must be installed on the client system.
