• Pipe PhantomJS output to FFmpeg

  10 avril 2017, par Hasse Andersen

  I am running PhantomJS using Selenium WebDriver (C#).

  I’m trying to video record my browser using FFmpeg as shown in the 2 tutorials :

  https://mindthecode.com/recording-a-website-with-phantomjs-and-ffmpeg/

  https://gist.github.com/phanan/e03f75082e6eb114a35c

  As explained in the tutorials, I’ll need to pipe output the phantomJS process to ffmpeg.

  I know how to add arguments to phantomjs, like the following :

      var svz = PhantomJSDriverService.CreateDefaultService();
  
      svz.AddArgument("ffmpeg -y -c:v png -f image2pipe -r 24 -t 10  -i - -c:v libx264 -pix_fmt yuv420p -movflags +faststart output.mp4");
  
      var driver = new PhantomJSDriver(svz);

  However, I don’t know how to add the argument as pipe. I have tried adding the pipe symbol before the actual argument but that doesn’t seem to work.

  So, my question is, how do I pipe the output of PhantomJS using selenium webdriver ?
