==== Classroom activities - Wednesday ====
 
; Discussion of term project and final
* [[COAP:COAP-2100/term project|term project]]
 
; Principles
* Recall of HTML5 video principles
* Track languages: SRT, WebVTT, [[Timed Text]], etc.
* [[WebVTT]] (A video track language)
* Using JavaScript libraries
 
; LeanBackPlayer exercise
 
* [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 "project5".
 
* 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)
 
* Create a new HTML5 file using the template below:

** 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
* Exam
** Deleted some important Line of code
** Have syntax errors. Validate your code
 
* Add tracking data

* 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.
