overlay_qsv hard coded to use nv12 as output format. Now use the format
of the first input to set output format. Now the following command
works:
ffmpeg -hwaccel qsv -c:v hevc_qsv -i input_p010.265 -hwaccel qsv -c:v hevc_qsv \
-i input2_p010.265 -filter_complex "[0:v][1:v]overlay_qsv=x=0:y=0:alpha=255, \
hwdownload,format=p010le" -f rawvideo -y output_p010.yuv
