Intel® Video Processing Library (Intel® VPL)

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

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

[!IMPORTANT]

Intel® VPL Tools are no longer in this repository. They have all been moved to https://github.com/intel/libvpl-tools

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

Intel® VPL GPU Runtime for use on Intel® Iris® Xe graphics and newer
Intel® Media SDK for use on legacy Intel® graphics

Architecture

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:

GPU	Media SDK	Intel® VPL	Microsoft DirectX Support
Earlier platforms, back to BDW (Broadwell)	:heavy_check_mark:		DX9/DX11
ICL (Ice Lake)	:heavy_check_mark:		DX9/DX11
JSL (Jasper Lake)	:heavy_check_mark:		DX9/DX11
EHL (Elkhart Lake)	:heavy_check_mark:		DX9/DX11
SG1	:heavy_check_mark:		DX9/DX11
TGL (Tiger Lake)	:heavy_check_mark:	:heavy_check_mark:	DX9/DX11*
DG1 (Intel® Iris® Xe MAX graphics)	:heavy_check_mark:	:heavy_check_mark:	DX11*
RKL (Rocket Lake)		:heavy_check_mark:	DX11
ADL-S (Alder Lake S)		:heavy_check_mark:	DX11
ADL-P (Alder Lake P)		:heavy_check_mark:	DX11
ADL-N (Alder Lake N)		:heavy_check_mark:	DX11
DG2 (Intel® Arc™ A-Series Graphics)		:heavy_check_mark:	DX11
ATSM (Intel® Data Center GPU Flex Series)		:heavy_check_mark:	DX11
RPL-S (Raptor Lake S)		:heavy_check_mark:	DX11
RPL-P (Raptor Lake P)		:heavy_check_mark:	DX11
MTL (Meteor Lake)		:heavy_check_mark:	DX11
ARL-S (Arrow Lake S)		:heavy_check_mark:	DX11
ARL-H (Arrow Lake H)		:heavy_check_mark:	DX11
LNL (Lunar Lake)		:heavy_check_mark:	DX11
Future platforms...		:heavy_check_mark:	DX11

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.

Installing Intel® VPL

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

Using Intel® VPL

Configure your shell environment

If you did not install to standard system locations, you need to set up the environment, so tools like CMake and pkg-config can find the library and headers.

For Linux:

source <vpl-install-location>/etc/vpl/vars.sh

For Windows:

<vpl-install-location>\etc\vpl\vars.bat

Link to Intel® VPL with CMake

Add the following code to your CMakeLists, assuming TARGET is defined as the component that wants to use Intel® VPL:

if(WIN32 AND CMAKE_SIZEOF_VOID_P EQUAL 4)
 set(CMAKE_LIBRARY_ARCHITECTURE x86)
endif()
find_package(VPL REQUIRED)
target_link_libraries(${TARGET} VPL::dispatcher)

Link to Intel® VPL from Bash with pkg-config

The following command line illustrates how to link a simple program to Intel® VPL using pkg-config.

gcc program.cpp `pkg-config --cflags --libs vpl`
