It's unclear what you're asking. Do you want to know how to stack multiple images horizontally and then overlay another image on top?– GyanCommented Apr 14, 2016 at 15:33

To overlay a half-sized version of a video in the center of an image, use
ffmpeg -loop 1 -i image -i video
-filter_complex "[1]scale=iw/2:-1[ovrl];
[0][ovrl]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2:shortest=1[v]"
-map "[v]" -map 1:a -c:v libx264 -c:a copy output.mp4
To frame the video:
ffmpeg -loop 1 -i image -i video loop 1 -i frame
-filter_complex "[1]scale=iw/2:-1[ovrl];
[2][ovrl]scale2ref=iw*1.2:-1[fr][ol];
[fr][ol]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2:shortest=1[fv];
[0][fv]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2:shortest=1[v]"
-map "[v]" -map 1:a -c:v libx264 -c:a copy output.mp4
If you composite the frame onto the background image beforehand, in ffmpeg or elsewhere, you can just use that resultant image with the first command. Of course, you'll lose freedom of movement for the video overlay.
