blind-stack - Overlay videos
blind-stack [-b] bottom-stream ... top-stream
blind-stack prints the video from the file bottom-stream to
stdout, but draws the videos from the succeeding arguments on top of the video
from bottom-stream, drawing them in order, starting with the video
specified direct after bottom-stream and ending with top-stream.
The specified files can be any type, except directory, including pipes.
The output video will be as long as the longest input video.
- -b
- Instead of drawing the videos on top of each other, for each pixel in each
frame, print the average colour for each input stream's corresponding
pixel and frame.
