# d3d11download

Downloads Direct3D11 texture memory into system memory

## Example launch line

    gst-launch-1.0 filesrc location=test_h264.mp4 ! parsebin ! d3d11h264dec ! \
      d3d11convert ! d3d11download ! video/x-raw,width=640,height=480 ! mfh264enc ! \
      h264parse ! mp4mux ! filesink location=output.mp4

This pipeline will resize decoded (by d3d11h264dec) frames to 640x480 resolution by using d3d11convert. Then it will be copied into system memory by d3d11download. Finally downloaded frames will be encoded as a new H.264 stream via mfh264enc and muxed via mp4mux
