Enabled one thread per plane, used the test command for 1080P video
(YUV420P format) as follow:

ffmpeg -i 1080p.mp4 -an -vf hqdn3d -f null /dev/nul

This optimization improved the performance about 30% in 1080P YUV420P
case (from 110fps to 143fps), also pass the framemd5 check and FATE.

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 -

There is no change in the encoded bitstream, but this
ensures that the written field length is consistent
with the reference implementation.

Unused bytes are zeroed out for backwards compatibility.

Linux and OSX systems support basename and dirname via <libgen.h>, I plan to
make the wrapper interface conform to the standard interface first.
If it is feasible, I will continue to modify it to call the system interface
if there is already a system call interface.

You can get more description about the system interface by below command:
 "man 3 basename"
