GPU copy enables or disables GPU accelerated copying between video
and system memory. This may lead to a notable performance improvement.
Memory must be sequent and aligned with 128x64.
CMD:
ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -c:v h264_qsv
-gpu_copy on -i input.h264 -f null -
or:
ffmpeg -c:v h264_qsv -gpu_copy on -i input.h264 -f null -
