  display_errors = On

** Using JavaScript libraries


Topics (TBA in detail)
; LeanBackPlayer exercise
* XML
* SVG
* Document formats


==== Homework 7 ====
* [http://leanbackplayer.com/ LeanBack Player]
* Download from [http://leanbackplayer.com/player_download.html?type=player here] and unzip the library within a folder that you could name "project6".
 
* Create the player code with the [http://leanbackplayer.com/generator/ 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:
<source lang="XML">
<!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>
</source>
 
* 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
** Code below is taken from this file and should be inserted right after the source elements
 
Track elements
<source lang="XML">
<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''

==== Wednesday ====
 
'''1) Exam/term project Q/A'''


; Task
'''(2) WebVTT hands-on'''
Create a PHP program that can process a simple quiz made with radio buttons. In addition, it should include 1-2 text input fields that ask for a name. Start from the example presented in the [[HTML forms tutorial]].
* Get the HTML file done on Monday and add captions files, look at [http://tecfa.unige.ch/guides/html/html5-video/html5-video-track-leanbackplayer.html this example]
* You can start from this VTT file: [http://tecfa.unige.ch/guides/html/html5-video/subtitles_en.vtt subtitles_en.vtt] (rename it if necessary)


* You can reuse elements from the JavaScript (hw 6) exercise. You also could relate the topic of the quiz to the term project.  
If you missed class:
* You may use questionnaire items from other sources, but do '''not plagiarize'''. If you reuse assets from another source, cite the source. Plagiarism is simply not accepted and will be sanctioned.
* Download and dezip [http://leanbackplayer.com/player_download.html?type=player LeanBack Player]
* Save the following file and start from there: [http://tecfa.unige.ch/guides/html/html5-video/html5-video-track-leanbackplayer.html html5-video-track-leanbackplayer.html]


Note: CS students familiar with HTML forms and PHP can use other HTML forms but be warned that, for example,  processing checkboxes is more difficult.
'''(3) Creating screencasts:'''
* http://www.screencast-o-matic.com


; Tips
'''(4) Video and audio editing (part II)'''
* Validate your HTML code
* Use the server log files for finding PHP errors or keep the following line at the start of your PHP code:
error_reporting(E_ALL);


; Evaluation criteria
* [http://windows.microsoft.com/en-us/windows7/products/features/movie-maker Windows Movie Maker]
* Ergonomics and content (does the quiz "make sense" and is it interesting)
* User experience (does it look good)
* HTML and CSS code (is it valid)
* Style and presentation
* PHP (is your code running, does it compute ok)


; Due
==== Homework 7 ====
* Before Wednesday week 8 class


; Submission
None, but see homework 6 announced in [[COAP:COAP-2100/week6|week 6]]
* Submit the files (*.html, *.php and if needed *.css, pictures, etc.) to the world classroom
