# 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](https://intel.github.io/libvpl) 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](./api/vpl/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](https://github.com/oneapi-src/oneVPL-intel-gpu) for use on Intel® Iris® Xe graphics and newer
- [Intel® Media SDK](https://github.com/Intel-Media-SDK/MediaSDK) for use on legacy Intel® graphics

## Architecture
```mermaid

```

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](INSTALL.md).
- from Linux packages.  See [Intel® software for general purpose GPU capabilities](https://dgpu-docs.intel.com/)
