You can configure H.264 decoding and network protocol options for remote desktop and application sessions that use the VMware Blast display protocol.
The maximum resolution that is supported depends on the capability of the graphical processing unit (GPU) on the client. A GPU that can support 4K resolution for JPEG/PNG might not support 4K resolution for H.264. If a resolution for H.264 is not supported, Horizon Client uses JPEG/PNG instead.
H.264 decoding is supported on AMD, NVIDIA, and Intel GPUs. H.264 decoding requires that the graphics library OpenGL 3.2 or later is installed for AMD and NVIDIA GPUs.
If you plan to use H.264 decoding with a NVIDIA GPU, install VDPAU (Video Decode and Presentation API for Unix). VDPAU is no longer included with the latest NVIDIA driver and must be installed separately.
mks.enableGLBasicRenderer = TRUEto /etc/vmware/config, /usr/lib/vmware/config, or ~/.vmware/config. The configuration files are processed in the following order:
H.264 is not supported on SLED 11 SP4 with Intel GPU because the xorg version is too old.
This feature requires Horizon Agent 7.0 or later.
- In the desktop and application selector window, select VMware Blast in the left pane of the Settings window. or click the Settings icon in the upper-right portion of the window, and select
- Configure the decoding and network protocol options.
Select this option to allow H.264 decoding in Horizon Client. When this option is selected (the default setting), Horizon Client uses H.264 decoding if the agent supports H.264 software encoding. If the agent does not support H.264 software encoding, Horizon Client uses JPG/PNG decoding.
Deselect this option to use JPG/PNG decoding.
Select this option to allow UDP networking in Horizon Client. When this option is selected (the default setting), Horizon Client uses UDP networking if UDP connectivity is available. If UDP networking is blocked, Horizon Client uses TCP networking.
Deselect this option to use TCP networking.Note: UDP is disabled by default on a Horizon remote desktop. For UDP to work, it must be enabled on the desktop, the client, and the Blast Secure Gateway (BSG).
