does anyone know how to run a os x shell command from processing? i want to run something with parameters. like

"ffmpeg -f image2 -i /temp/burn_%03d.tif -r 25 -s 720x1280 -c prores -y /Users/Administrator/Desktop/burnprores.mov"

i'm trying to automatically make quicktime movies from frames.

i've tried using the open() command, but can't get it to work.

i've used the

String [] params{

"ffmpeg", " -f image2 -i /temp/burn_%03d.tif -r 25 -s 720x1280 -c prores -y /Users/Administrator/Desktop/hello.mov"

}

then open(params);

but that didn't work

any suggestions?

thanks!

You are supposed to put each space-separated string in a separate string. You can keep the whole command as one string and use split() to do this.

i found this was better way

import java.io.*;void setup() { size(200, 200);}void draw() {}void mousePressed() { String[] params = { sketchPath + "/pstoedit", "-f", "gcode", sketchPath + "/isCircleSqPlain.svg", sketchPath + "/isCircleSqPlain.gcode" }; print("mousePressed"); exec(params);}
