NVIDIA Capture SDK (formerly GRID SDK) enables developers to easily and efficiently capture, and optionally encode, the display content or an application’s graphics context.
The NVIDIA Capture SDK enables game streaming, application streaming and remote desktop displays on NVIDIA hardware (local, remote or cloud). It provides the ability to capture the desktop buffer or application render target as an image or compressed video bitstream that can be transmitted to remote clients or stored locally.

Capture the full desktop (NVIDIA Frame Buffer Capture aka NvFBC)
NvFBC works by capturing the entire contents of the desktop to a GPU buffer without stalling, or interfering with, the other work on the GPU. On Windows, the capture can occur with the Windows Desktop Manager enabled or disabled. This buffer can then be encoded using H.264 or HEVC via on-chip hardware video encoder through the NvEncode API.
VMware Horizon Blast uses NVIDIA Capture SDK, and has demonstrated that using the Capture and Encode SDK improves latency, increases the number of users per server, reduces bandwidth, and lowers CPU utilization. The VMware case study blog can be found here.
NVIDIA Capture SDK can be used for desktop or application streaming from a private cloud. In order to setup a private cloud to develop and validate streaming functionality, there are two options
The NVIDIA Capture SDK includes a collection of code samples that demonstrate how to use the SDK APIs to capture either the desktop or a window and then send the contents to the NVIDIA Hardware Encoder. Reference the NVIDIA Capture SDK Samples Guide included in the download package for more information on getting started.
