blind-translate - Perform framewise translation of a video
blind-translate [-pw] translation-stream
blind-translate reads a video from stdin and translation operands from
translation-stream, and perform framewise translation of the video and
prints the resulting video to stdout.
translation-stream is a video that is 1 pixel wide and 1
pixel high. The first pixel value in a frame is used as the translation
value for the X-axis in the same frame in the video, and the second pixel
value is used as the translation value for the Y-axis. The remaining two
pixel values are ignored.
If stdin is longer than translation-stream, the remainder
of stdin is printed with the last translation or no translation if
translation-stream does not contain any translations. If stdin is
shorter than translation-stream, the remainder of
translation-stream is ignored but may be partially read.
blind-translate requires enough free memory to load a full frames into
memory if -w is used or a frame row otherwise. A frame or frame row
requires 32 bytes per pixel it contains.

- Wrap video around the edges.
- The values in translation-stream is to be treat as the position,
measured form the top-left corner, in the input video that shall be used
at the top-left corner of the output video.
