1 HTML Structure & Web Design Basics
Media and Interactivity Basics Week /25/ Course TECH Dr. Simon Qiu Textbook Contents of Pearson Education, Basic of Web Design

2 Learning Outcomes Describe types of multimedia files used on the Web
Configure hyperlinks to multimedia files Configure audio and video on a web page with HTML5 elements Configure a Flash animation on a web page Use the CSS3 transform and transition properties Describe the purpose of the HTML5 canvas element Week /25/ Course TECH Dr. Simon Qiu Textbook Contents of Core Web Programming

3 Helper Applications & Plug-ins
A program that can be designated to handle a particular file type (such as .wav or.mpg) to allow the user to view or otherwise utilize the special file. The helper application runs in a separate window from the browser. Plug-In A newer and more common method Plug-ins run right in the browser window so that media objects can be integrated directly into the web page. Common used plug-ins and helper applications: Adobe Flash Player, Shockwave Player; Windows Media Player; Apple QuickTime; RealPlayer; Why doesn’t my audio/video file play?

4 Containers & Codecs – New about HTML5 video and audio – No Plug-in Needed.
HTML5 audio & video Native to the browser Browsers do not support the same codecs Container Designated by the file extension – contains the media and metadata Codec The algorithm used to compress the media

5 Common Audio File Types
.wav Wave File .aiff Audio Interchange File Format .mid Musical Instrument Digital Interface (MIDI) .au Sun UNIX sound file .mp3 MPEG-1 Audio Layer-3 .ogg Ogg Vorbis (open-source) . m4a MPEG 4 Audio. This audio-only MPEG-4 format is supported by Quicktime, iTunes, and iPods.

6 Common Video File Types
.mov Quicktime .avi Microsoft Audio Video Interleaved .wmv Windows Media File .flv Flash Video File .mpg MPEG (Motion Picture Experts Group) .m4v .mp4 (MPEG-4) .ogv Ogg Theora (open-source) .webm VP8 codec (open video format, free)

7 Copyright Issues Only publish web pages, images, and other media that you have personally created or have obtained the rights or license to use. Ask permission to use media created by another person instead of simply “grabbing” it. All work (including web pages) are automatically copyrighted even if there is not copyright mark or date. Fair Use Clause of the Copyright Act Creative Commons – A new approach to copyright

8 Configure Audio & Video
Most basic method to provide audio or video files: Hyperlink <a href=“wdfpodcast.mp3" title=“Web Design Podcast”>Web Design Podcast</a> Demo: podcast/podcast.html

9 What is Adobe Flash? A popular multimedia application
Create multimedia which adds visual interest and interactivity to web pages Flash movies are saved in “.swf” files Perception of speedy display .swf files play as they download Flash Player Free browser plug-in Widely installed on browsers

10 HTML5 Embed Element <embed type="application/x-shockwave-flash" src="fall5.swf" width="640" height="100" quality="high” title="Fall Nature Hikes">

11 HTML5 Audio & Source Elements
<audio controls="controls"> <source src="soundloop.mp3" type="audio/mpeg"> <source src="soundloop.ogg" type="audio/ogg"> <a href="soundloop.mp3">Download the Audio File</a> (MP3) </audio>

12 HTML5 Video & Source Elements
<video controls="controls" poster="sparky.jpg" width="160" height="150"> <source src="sparky.m4v" type="video/mp4"> <source src="sparky.ogv" type="video/ogg"> <a href="sparky.mov">Sparky the Dog</a> (.mov) </video>

13 Use the iframe element to embed YouTube Video
<iframe src="http://www.youtube.com/embed/VIDEO_ID" width="640" height="385"> View the <a href="http://www.youtube.com/watch?v=VIDEO_ID">YouTube Video</a> </iframe>

14 CSS3 Transform Property
Allows you to rotate, scale, skew, or move an element Example: -webkit-transform: rotate(3deg); -moz-transform: rotate(3deg); -o-transform: rotate(3deg); -ms-transform: rotate(3deg); transform: rotate(3deg);

15 CSS3 Transition Property
Provides for changes in property values to display in a smoother manner over a specified time. Example: nav a:hover { color: #869dc7; background-color: #eaeaea; -webkit-transition: background-color 2s linear; -moz-transition: background-color 2s linear; -o-transition: background-color 2s linear; transition: background-color 2s linear; }

16 HTML5 Canvas Element Configures dynamic graphics
Draw lines, shapes, text, image Interact with actions taken by the user Canvas API (application programming interface) JavaScript – client-side scripting language <script> function drawMe() { var canvas = document.getElementById("myCanvas"); if (canvas.getContext) { var ctx = canvas.getContext("2d"); ctx.fillStyle = "rgb(255, 0, 0)"; ctx.font = "bold 3em Georgia"; ctx.fillText("My Canvas", 70, 100); ctx.fillStyle = "rgba(0, 0, 200, 0.50)"; ctx.fillRect (57, 54, 100, 65); } </script> ", "width": "800" }
