Error using ffmpeg image2pipe with phantomjs to render video from webpage screenshots
14 novembre 2016, par user1690179I am trying to use phantomjs with ffmpeg to complie videos from screenshots of a webpage as described here :
https://groups.google.com/forum/# !msg/phantomjs/wluVGGjhL90/oGBXqh7QP44JI have the following test.js file :
var page = require('webpage').create();
page.clipRect = { top: 0, left: 0, width: 900, height: 800};
page.viewportSize = { width: 900, height: 800};
var url = 'http://dl.dropbox.com/u/621993/voronoi/voronoi.html';
var frames = 100;
page.open(url, function(){
setInterval(function(){
page.render('/dev/stdout');
if( frames == 0 ){
phantom.exit();
}
frames--;
}, 100);
});Then I run this command, taken from the link above :
$ phantomjs test.js |ffmpeg -c:v png -f image2pipe -r 10 -sameq -i - -y test.mp4Including -sameq causes an error in ffmpeg, so I took it out and ran :
$ phantomjs test.js |ffmpeg -c:v png -f image2pipe -r 10 -i - -y test.mp4I get the following output from ffmpeg :
