Intel® Video Processing Library (Intel® VPL)

Intel® Video Processing Library (Intel® VPL) supports AI visual inference, media delivery, cloud gaming, and virtual desktop infrastructure use cases by providing access to hardware accelerated video decode, encode, and frame processing capabilities on Intel® GPUs.

See the specification for additional information.

This repository contains the following components:

• Copies of the Intel® VPL API header files. The version of the API is listed in the mfxdefs.h file.

• Intel® VPL Dispatcher

• Examples demonstrating API usage

• Command line tools To use Intel® VPL for video processing you need to install at least one implementation. Here is a list:

• oneVPL-intel-gpu for use on Intel® Iris® Xe graphics and newer

• Intel® Media SDK for use on legacy Intel® graphics

As shown in this diagram, the Intel® VPL Dispatcher forwards function calls from the application to use the selected runtime.

Dispatcher behavior when targeting Intel® GPUs

Runtime loaded by Intel® VPL Dispatcher and their Microsoft* DirectX* support:

For TGL and DG1, if both Intel® VPL and Intel® Media SDK runtime are installed then the Intel® VPL Dispatcher will prefer Intel® VPL runtime unless the application requests D3D9 by setting the filter property "mfxImplDescription.AccelerationMode" to MFX_ACCEL_MODE_VIA_D3D9.

Installation and Usage

Installation options

Intel® VPL may be installed:

• from source code. See install and use instructions at INSTALL.md.
• from Linux packages. See Intel® software for general purpose GPU capabilities
