Usage:
|
|
. th.sh COLUMNS ROWS SIZE INPUT
|
|
COLUMNS means number of columns;TILE is in the form 'MxN' (where M * N should match NFRAMES), e.g., 4x4;
|
|
ROWS means nubler of rows;
|
|
SIZE is the length of the longer side of the output, e.g., 1920 if you want
|
|
to get an 1920*1080 output image;
|
|
INPUT is the path to the input file;
|
|
OUTPUT is the path to the output file (make sure intermediate directories
|
|
exist).
|
|
|
|
Example:
|
|
. th.sh 3 14 1920 video.mp4
