GIF to frames

ffmpeg -i video.mpg image%d.jpg

convert -coalesce animated.gif image%05d.png

High quality GIF

with ffmpeg / based on this article

• Generate a palette :

#!/bin/sh
start_time=30
duration=3
ffmpeg -y -ss $start_time -t $duration -i input.avi \
-vf fps=10,scale=320:-1:flags=lanczos,palettegen palette.png

• Output the GIF using the palette :

#!/bin/sh
start_time=30
duration=3
ffmpeg -ss $start_time -t $duration -i input.avi -i palette.png -filter_complex \
"fps=10,scale=320:-1:flags=lanczos[x];[x][1:v]paletteuse" output.gif

Grabbing each frame of an HTML5 Canvas

Using PhantomJS.

Example with this canvas.

var webPage = require('webpage');
var fs = require('fs');
var page = webPage.create();

var NB_FRAME = 100;
var current = 0;

page.open('http://www.effectgames.com/demos/canvascycle/?sound=0',
function(status) {
  if (status === "success") {
      var current = 0;
      var grabber = setInterval(function () {
          var frame = page.evaluate(function() {
           return document.getElementById('mycanvas').toDataURL("image/png").split(",")[1];
          });
          fs.write("./frame-" + current + ".png",atob(frame), 'wb');
      if (++current === NB_FRAME) {
         window.clearInterval(grabber);
         phantom.exit(0);
      }
    }, 1000);
  }
});
