+It provides the user with on-gpu D3D11 textures, in the form of ffmpeg D3D11VA frames, which can then be directly encoded by a compatible hardware encoder, for example [[HWAccelIntro#NVENC|NVENC]] encoders:
 {{{
 ffmpeg -init_hw_device d3d11va -filter_complex ddagrab=0 -c:v h264_nvenc -cq:v 20 output.mkv

+For Intel GPUs that support [[Hardware/QuickSync|QuickSync]] (QSV) encoders, use the [https://ffmpeg.org/ffmpeg-filters.html#hwmap hwmap] filter to wrap D3D11 frames into QSV frames:
