FFmpeg's hardware acceleration (HWAccel) is a feature that uses the decoders and encoders of a GPU or dedicated chip to reduce CPU load and speed up processing. Platform-specific APIs such as NVIDIA's NVDEC/NVENC, Intel's VAAPI and QSV, Windows's D3D11VA and DXVA2, and macOS's VideoToolbox are selected with the -hwaccel option and dedicated codec names. Support depends on build options and drivers.
