Multimedia redirection (MMR) delivers the multimedia stream directly to client computers by using a virtual channel.

With MMR, the multimedia stream is processed, that is, encoded and decoded, on the client system. Local hardware formats and plays media content, thereby offloading the demand on the ESX/ESXi host.

View Client and View Client with Local Mode support MMR on the following operating systems:

Windows XP

Windows XP Embedded

Windows Vista

The MMR feature supports the media file formats that the client system supports, since local decoders must exist on the client. File formats include MPEG2-1, MPEG-2, MPEG-4 Part 2; WMV 7, 8, and 9; WMA; AVI; ACE; MP3; and WAV, among others.

Use Windows Media Player 10 or later, and install it on both the local computer, or client access device, and the View desktop.

You must add the MMR port as an exception to your firewall software. The default port for MMR is 9427.


The View Client video display hardware must have overlay support for MMR to work correctly.

Windows 7 clients and Windows 7 View desktops do not support MMR. For Windows 7 clients agents, use Windows media redirection, included with RDP 7.
