With multimedia redirection (MMR), the multimedia stream is processed, that is, decoded, on the client system. The client system plays the media content, thereby reducing the load on the ESXi host.

View remote desktop

  • Single-user desktops must have View Agent 6.0.2 or later, or Horizon Agent 7.0 or later, installed.

  • Session-based desktops must have View Agent 6.1.1 or later, or Horizon Agent 7.0 or later, installed on the RDS host.

  • For information about operating system requirements and other software requirements and configuration settings for the remote desktop or application, see the topics about Windows Media Multimedia Redirection in Setting Up Desktop and Application Pools in View.

Horizon Client computer or client access device

Because MMR offloads media processing from the server to the client, the client has the following minimum hardware requirements.

Processor:

Intel Pentium 4 or AMD Athlon dual-core

Processor speed:

1.5 GHz for common case, or 1.8 GHz for Full HD

Memory:

2 GB RAM

Video adapter:

Hardware accelerated

You must install one of the following libraries to avoid video playback issues:

  • GStreamer core library and gstreamer-ffmpeg 0.10

  • GStreamer core library and fluendo 0.10

On SLED 11 SP4, if you encounter video playback issues such as a black screen, remove the library libvdpau.

On HP thin clients, you must remove the file /usr/lib/gstreamer-0.10/libgstfluvadec.so to avoid video playback issues such as a Horizon Client crash or a black screen.

On Dell Wyse thin clients, video playback might not work with the pre-installed fluendo library. To resolve the problem, contact Dell support to obtain the latest fluendo library.

Supported media formats

Media formats that are supported on Windows Media Player are supported. For example: M4V; MOV; MP4; WMP; MPEG-4 Part 2; WMV 7, 8, and 9; WMA; AVI; ACE; MP3; WAV.

Note:

DRM-protected content is not redirected through Windows Media MMR.

MMR is not enabled by default. To enable it, you must set the configuration option view.enableMMR. For more information, see Horizon Client Configuration Settings and Command-Line Options.
