Hello,
Is it possible to record video format .js (javascript) on the hard drive through internet. Is there any free software or some tips for the same. Thank you

have a video format that looks like this:

Code:

---

{ 
  frm : "JSVID",  // format id tag 
  ver : 1,  // version number of format 
  width : 320,  // width of video 
  height : 240,  // height of video 
  rate : 15,  // framerate (frames per second) 
  frames : 495,  // number of frames in file 
  data : { 
    video : [ // here comes 495 data:uris containing base64 encoded jpeg image frames 
      "data:image/jpeg;base64,/9j/4AAQSkZJRgABAgEASABIAAD/7gAOQWRv ... ", 
      "data:image/jpeg;base64,/9j/4AAQSkZJRgABAgEASABIAAD/7gAOQWRv ... ",

A Clipstream™ Video .js file is a separate javascript document that contains the applet code necessary to play a Clipstream formatted video file (.vcs). A web page can then embed a link calling this JavaScript document.

How do I get a Clipstream™ Video into a .js file?
By default, the Clipstream™ Video 3 Encoder will output both a .js file, the video files (.vcs), and a web page that links to the .js file. If you have previously disabled .js output you can re-enable it by checking "Generate JS/HTML after encoding finished" box in the Encoder main window.
