NAME

blind-extend - Add margins to a video

SYNOPSIS

blind-extend [-l left] [-r right] [-a above] [-b below] [-t]

DESCRIPTION

blind-extend reads a video from stdin and prints a version of it, where extra space has been to its sides, to stdout.

OPTIONS

-l left

Extend the video by left pixels to the left side of the video. left most be a non-negative integer.

-r right

Extend the video by right pixels to the right side of the video. right most be a non-negative integer.

-a above

Extend the video by above pixels to the top of the video. above most be a non-negative integer.

-b below

Extend the video by below pixels to the bottom of the video. blelow most be a non-negative integer.

-t

Instead of adding transparent pixels, draw the end of the input videos in the new room, such that the right-most part of the video has is put side-by-side with the left-most part of the video, and analogously for the other sides.

REQUIREMENTS

blind-extend requires enough free memory to load two full frames into memory, one of the size of the source video’s frames, and one of the size of the target video’s frames. A frame requires 32 bytes per pixel it contains. blind-extend has not been optimised for memory usage, but instead for code simplicity.
