- LeanBackPlayer exercise
- LeanBack Player
- Download from here and unzip the library within a folder that you could name "project6".
- 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)
- In the directory you just created, 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 -->
<hr/>
<a href="http://validator.w3.org/">W3C validator</a>
</body>
</html>
- Fix the URLs in the code:
- Reaplce the abolute "http://yourdomain.com/..." URL by "js.player" and css.player. Look at the code and think !.
- 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 not show then you likely:
- must have put the JS and CSS libraries in some other place (not the same directory). Fix the URLs, look at your directory !
- must have deleted some important line of code
- must have have syntax errors: validate your code
- Tip: Open the error console in your browser: In Firefox: Tools->Web Developer->Error console
- Using track with LeanbackPlayer
- See WebVTT
- Look at the code of http://tecfa.unige.ch/guides/html/html5-video/html5-video-track-leanbackplayer.html
