Code for showing a grid of any number of videos with automatic column and row count

[jak352]

I have made some code for showing a grid of videos while automatically allocating a column and row count (leaving black space where necessary). Here's the code to paste into the Video Processor plugin in an empty track with any number of video tracks below it:

// grid of videos - automatically draws any number of videos from tracks
x=0;
count_tracks = input_track_count();
cols = ceil(sqrt(count_tracks));
rows = ceil(count_tracks/cols);
loop(cols*rows,
gfx_blit(input_track(x), 1 /* preserve aspect */,
(x%cols)*project_w/cols, ((x - (x%cols))/cols)*project_h/rows, // position
project_w/cols,project_h/rows // output width and height
);
x += 1;
);

There are some more code examples in my feature request post at:

COVID-19 is currently inspiring lots of people to make videos like this.
