** Tick most everything except autoplay and loop

* Fix the URLs in the code:
** In particular substitute the absolute "http://yourdomain.com/" by "".
** Change the name of the video files if needed.
** Change the name of the poster files, i.e. substitute "http://leanbackplayer.com/videos/poster/elephants_dream_640x360.jpg" by "myposter.jpg".
* Test. If the video does show then you likely:
** Put the library in some other place (not the same directory). Fix the URLs
** Deleted some important Line of code
** Have syntax errors. Validate your code
* Add tracking data
** See [[WebVTT]]
** Look at the code of http://tecfa.unige.ch/guides/html/html5-video/html5-video-track-leanbackplayer.html

Classroom activities - Wednesday

Discussion of term project and final
Principles
  • Recall of HTML5 video principles
  • Track languages: SRT, WebVTT, Timed Text, etc.
  • WebVTT (A video track language)
  • Using JavaScript libraries
LeanBackPlayer exercise
  • LeanBack Player
  • Download from here and unzip the library within a folder that you could name "project5".
  • Create the player code with the [HTML5 Generator].
    • Tick most everything except autoplay and loop
    • You already can substitute the video file names (but you also can do that later). We suggest doing it now, e.g. use myvideo.mp4, myvideo.webm, etc.
    • Keep the browser tab open (you will need to copy/paste the code)
  • Create a new HTML5 file using the template below:
<!doctype html>
<html>
  <head>
    <meta charset="UTF-8"/> 
    <title>HTML 5 video</title>

    <!-- Insert the header code about here and kill this line -->

  </head>
    <body>

      <h1>Title that you should set </h1>
      <p>Intro that you should change ....</p>

   <!-- Insert the body code about here and kill this line -->

  • Test. If the video does show then you likely:
    • Put the library in some other place (not the same directory). Fix the URLs
    • Deleted some important Line of code
    • Have syntax errors. Validate your code

Homework 5

  • Create an HTML5 file that includes at least a video and an audio
  • The page should be "meaningful" and usable with respect to a target population of your choice. (I.e. don't create a page for the instructor, identify an objective and implement ...)
  • You may copy/paste text and use media files from some other sources under the condition that you cite these sources.
  • You may keep the HTML very simple (ie. only use h1 and p tags)
  • In order to get a high mark with respect to Artwork and appeal, you should consider using some CSS, e.g. add a float:right property to the video element. In case you don't know CSS at all, you may compensate with excellent contents.
  • Submit the files to the worldclass room. Make sure to include the media files unless you link to accessible URLs.
  • Due: Monday, week 7, before class

Homework 6

Notice: Technology of HTML5 players will not be tested in the final exam. If you already submitted four good homeworks, you can skip this one.....

  • Create an HTML5 file that includes at a video shown with an HTML5 Player. You can use LeanbackPlayer or any other.
  • The page should be "meaningful" and usable with respect to a target population of your choice. (I.e. don't create a page for the instructor, identify an objective and implement ...)
