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.


NVIDIA Capture SDK technology is used in VMware Horizon to stream virtual desktops

 

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 rendertarget as an image or compressed video bitstream that can be transmitted to remote clients or stored locally.

Key Features of NVIDIA Capture SDK


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.

 


Capture render context (NVIDIA Inband Frame Readback aka NvIFR)

 

NvIFR captures the content of an application’s DirectX, OpenGL or Vulkan render context. This captured buffer can then be encoded using H.264 or HEVC via on-chip hardware video encoder and NvEncode API.

 

Enterprise Case Study with NVIDA Capture SDK

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.

 

 

Resources

Getting Started

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

  1. Refer to the NVIDA Capture SDK FAQ for the supported Tesla, Quadro, or GRID product to use with the Capture SDK. Download the latest relevant NVIDIA Display Drivers for install on Windows or Linux systems.
  2. Use Amazon G2 instances for GPUs in the cloud. These are located in data centers in US East (Northern Virginia), US West (Northern California), US West (Oregon), and EU (Ireland) Regions. Refer to the documentation in the Capture SDK on setting up an account and AMI for use.

Code Samples

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.
