Microsoft announced the implementation of support for hardware-accelerated video encoding and decoding in WSL (Windows Subsystem for Linux), a layer for running Linux applications on Windows. The implementation makes it possible to use hardware acceleration of video processing, encoding and decoding in any applications that support VAAPI. Acceleration is supported for AMD, Intel and NVIDIA graphics cards.
GPU-accelerated video in a WSL-enabled Linux environment is provided through the D3D12 backend and VAAPI frontend in the Mesa package, interacting with the D3D12 API using the DxCore library, which allows for the same level of GPU access as native Windows applications .
