System Requirements for Multimedia Redirection (MMR)

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

• Remote desktops

  For information about operating system requirements and other software requirements and configuration settings, see the topics about Windows Media Multimedia Redirection in the Horizon Remote Desktop Features and GPOs document.

• Omnissa 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

  To avoid video playback issues, install one of the following libraries:

  • GStreamer core library and gstreamer-libav 1.0
  • GStreamer core library and fluendo 1.0

• Supported media formats

  Media formats that Windows Media Player supports, for example: M4V; MOV; MP4; MPEG-4 Part 2; WMV 7, 8, and 9; WMA; AVI; ACE; MP3.

  MP3 is not supported when using MMS and RTSP.

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

• GStreamer Framework

  Set up the GStreamer environment such that the framework consists of the graphics card, hardware acceleration API, and GStreamer plug-in that allow GStreamer to function properly. To ensure the best possible environment, set up your GStreamer environment using the information in this table for the NVIDIA and Intel graphic cards.

  GStreamer Framework Setup

  Graphics Card (including Driver)	Hardware Accelerator API	GStreamer Plug-in
  NVIDIA	VDPAU (libvdpau.so)	vdpau
  Intel	VAAPI (libvaapi.so)	gstreamer-vaapi
  --	OpenMax	gst-omx
  --	DCE	gstreamer-ducati
  AMD	OVD/UVD	Unavailable

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.
