blind-read-head - Reads the head from a video
reads the head a video from stdin, and prints it, without
the magic number, to stdout. The output will contain: the number of frames,
<space>, the width, <space>, the height, <space>, and the
pixel format. The output is text, and thus ends with a <newline>.
No excess bytes are read and blind-next-frame
(1) can be used to get the
first, and any following, frame from stdin.
