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 Signed-off-by: Wenbin Chen <wenbin.chen@intel.com>
