Monday
- 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 -->
<hr/>
<a href="http://validator.w3.org/">W3C validator</a>
</body>
</html>
- Fix the URLs in the code:
- In particular substitute the absolute "http://yourdomain.com/" by "js.player" or css.player.
- 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 library and the CSS 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
- Code below is taken from this file...
Track elements
<track enabled="true" kind="subtitles" label="EN"
src="subtitles_en.srt" srclang="en" type="text/x-srt"/>
<track enabled="true" kind="subtitles" label="EN VTT"
src="subtitles_en.vtt" srclang="en" type="text/vtt"/>
<track enabled="true" kind="subtitles" label="FR"
src="subtitles_fr.vtt" srclang="fr" type="text/vtt"/>
WebVTT template to copy/paste into a file called something like subtitles_en.vtt
WEBVTT
