Comment (by Balling):

 I just find out that it always selects left even for top left as can be
 checked by

 ffmpeg.exe -i cosmos.mkv -vf 'scale=in_h_chr_pos=0:in_v_chr_pos=128'
 -pix_fmt rgb24 qnfvarejwnfe3.rgb //for left
 ffmpeg.exe -i cosmos.mkv -vf 'scale=in_h_chr_pos=0:in_v_chr_pos=0'
 -pix_fmt rgb24 qnfvarejwnfe3.rgb //for top-left
