libavfilter/qsvvpp: Change the alignment to meet the requirement of YUV420P format
When process yuv420 frames, FFmpeg uses same alignment on Y/U/V
planes. VPL and MSDK use Y plane's pitch / 2 as U/V planes's
pitch, which makes U/V planes 16-bytes aligned. We need to set
a separate alignment to meet runtime's behaviour.
Now alignment is changed to 16 so that the linesizes of U/V planes
meet the requirment of VPL/MSDK. Add get_buffer.video callback to
qsv filters to change the default get_buffer behaviour.
Now the commandline works fine:
ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 3082x1884 \
-i ./3082x1884.yuv -vf 'vpp_qsv=w=2466:h=1508' -f rawvideo \
-pix_fmt yuv420p 2466_1508.yuv
