# d3d12scale

A Direct3D12 based video resizing element

## Example launch line

    gst-launch-1.0 videotestsrc ! video/x-raw,width=640,height=480 ! d3d12upload ! d3d12scale ! d3d12download ! video/x-raw,width=1280,height=720 ! fakesink

This will upload a 640x480 resolution test video to Direct3D12 memory space and resize it to 1280x720 resolution. Then a resized Direct3D12 frame will be downloaded to system memory space.
