Lecturefy

About

Lecturefy is a javascript bookmarklet that makes downloading SCPD lecture videos easier. Lecturefy doesn't actually download anything; instead, it generates links so that you can use your favorite download manager to download videos.

Requirements

The only thing that is required is a web browser that can play SCPD videos, which is any modern web browser. Tested on Chrome 55, Firefox 50, Safari 10.

Installation

Install as a bookmarklet

  1. Since Github doesn't allow embedding Javascript on this page, go here: http://www.erkserkserks.com/lecturefy/

  2. Drag "Lecturefy" link onto your bookmark toolbar.

  3. Done!

Install as a bookmarklet (manual)

This is how to do it in Chrome, but the process is the same for other browsers.

  1. Open the Bookmark Manager
  2. In the Bookmarks Bar folder (or any other folder), add a page
  3. Name the bookmark "Lecturefy" or something memorable, then fill in the URL with the javascript below:
javascript:(function(){"use strict";function getURLs(){function createStatus(){$(".page-header").after('<p id="lfy-status"> </div>')}function updateStatus(current,target){console.log("Fetching link "+current+" out of "+target+"...");$("#lfy-status").html("<h2> Fetching link "+current+" out of "+target+"...</h2>")}function doneStatus(target){console.log("Done fetching "+target+" links!");$("#lfy-status").html("<h2> Done fetching "+target+" links!</h2>")}createStatus();var buttons=$(".watchVideoButton");var lowQualityURLs=[];var highQualityURLs=[];var fetched=0;for(var i=0;i<buttons.length;i++){var button=$(buttons[i]);var lectureId=button.attr("data-lecture-id");var courseId=button.attr("data-course-id");var playerType=button.attr("data-type");$.ajax({url:"/"+playerType+"/LoadPlayer",type:"get",data:{lectureId:lectureId,courseId:courseId},success:function(result){if(result.length>0){var re=/file: "(.*?)"/g;lowQualityURLs.push(re.exec(result)[1]);highQualityURLs.push(re.exec(result)[1]);fetched++;var target=buttons.length;updateStatus(fetched,target);if(fetched==target){doneStatus(target);displayURLs(lowQualityURLs,highQualityURLs)}}}})}}function displayURLs(lowQualityURLs,highQualityURLs){function printURLs(array){for(var i=0;i<array.length;i++){console.log(array[i]);$("#lfy-urls").append('<br><a href="'+array[i]+'">'+array[i]+'</a></br>')}}$("#lfy-status").after('<div id="lfy-urls"> </div>');console.log("LQ Links: ");$("#lfy-urls").append("<h2> Low quality video links (smaller files): </h2>");printURLs(lowQualityURLs);$("#lfy-urls").append("<br></br>");console.log("HQ Links: ");$("#lfy-urls").append("<h2> High quality video links (larger files): </h2>");printURLs(highQualityURLs)}if(window.location.host.indexOf("mvideox")!==0){alert("Invalid domain name!\n"+"Go to mvideox.stanford.edu");return}if($("#readyToWatch").length===0){alert("No class selected!\n"+"Select a class, and try again.");return}if($("#lfy-urls").length!==0){console.log("#lfy-urls already exists! Quitting.");return}getURLs()})()

Usage

  1. Navigate to https://mvideox.stanford.edu/
  2. Choose a course and watch a lecture video (any lecture video)
  3. Click on the Lecturefy bookmarklet
  4. Done! Click on the links to download, or copy the links into your favorite download manager.

Since Lecturefy is just javascript, you can also run it in your browser's javascript console.
