Let's say the video dimensions are W x H.

I assume your watermark is correctly sized and smaller than W/10 x H/10. 
If not, add a scale filter before the pad in the command below.

Command would be

     ffmpeg -i video.mp4 -loop 1 -i image -filter_complex 
"[1]pad=W/10:H/10:(ow-iw)/2:(oh-ih)/2:color=black at 0,tile=10x10,trim=end_frame=1[wm];[0][wm]overlay" 
out.mp4
