VPL Decode->DPC++ Processing-> DX11 Render Example Project

NOTE: This codebase uses Git LFS for meadia files

Requirements:

• Visual Studio 2022
• oneAPI Base Toolkit 2024/2025
• CMake
• Intel GPU

External dependencies:

• OpenCV 4.8+
• Intel VPL dispatcher library (libvpl): https://github.com/intel/libvpl
• Intel Level-Zero headers and loader: https://github.com/oneapi-src/level-zero

Building the code

using CMakeLists.txt in the root of the project

1. Make sure external dependencies are built and installed in desired locations
2. CMake configure: set paths to installed external dependencies
3. Generate VS2022 solution/project files
4. Open generated solution and set the following projects to be build with Intel DPC++ 2024/2025: main, sycl-dx11-vpl, test_transcode.
5. Set main as a startup project

Running the Demo

Test video is located in 'content' subdirectory

Running:
main.exe --i \<path to a raw hvec video\>

Example:
main.exe --i ..\..\content\quiltB9F-07_4k.hevc

Controls: p - toggle image processing with SYCL on GPU (sobel edge detection overlayed on top of the source image) ESC - exit
