Multimedia It what makes the web so popular  Graphics  Sound  Animations  Movies Problem areas  File size 10 secs of CD quality sound takes 60 secs to download through a modem Movies are even worse  Different computers  Different browsers  Different formats

Multimedia wars Netscape develops MIME  Associates file type with application that utilizes it  Created embed element that allows multimedia file to be included into Html  Created plug-ins which are helper applications to play the multimedia files Microsoft implements the W3C object element for multimedia  Did not implement as W3C intended and only works for ActiveX controls which only runs on Microsoft O/S Object works in Netscape 6.0 The way to make multimedia work is to use both the embed and object elements

Getting the players Visitors can only view multimedia files if the have the correct players  Often users have to download and install the correct player  May require user to stop and restart Browser Moves them away from your web site Microsoft ActiveX doesn’t require restart You can look at your browser to see what plug-ins you all ready have

Netscape plugins

Getting Multimedia Files Create your own  Lots of free software to create files  Windows Media Player Download from web  Read license agreements carefully  Stick to standard formats Requires user to download new helper applications if file is not common

Linking media Files Upload multimedia file to server Type  A picture 06/we-are-nation.html 06/we-are-nation.html

Embedding A QuickTime Movie Create or Download A Quicktime movie  Requires a Macintosh computer to create  Has.mov extension For IE browsers use activeX control

Embedding QuickTime Movies For Browser other than IE <object type="video/quicktime" data=" e/diables.mov" width="320" height="256"> ia/forstandards.html

Embedding QuickTime Movies For All Broswers <object type="video/quicktime" data=" width="320" height="256">

Hints Width and height set the size of the box the movie is played in and not the size of the movie Classid’s are complicated and hard to remember  Create a template file for each file type and just change the sections  Use Microsoft ActiveX Control Pad

Microsoft ActiveX Control Pad

Scaling a quick time movie Adjust the size of the movie Two parts  The size of the box Height=h, width=w  The size of the movie For object For embed Factor can be  tofit – movie is size of box  aspect – movie is size of box but maintains aspect ratio  N – a multiplier (2 is twice as big)

Looping a QuickTime Movie Make the movie play over and over again  For object  For embed  option can be true - plays forever false – plays once palindrome – plays forward, then backward, then forward…

Pitting QuickTime Sounds QuickTime plays many sound files including MP3  Code is same as for movies except Src should be a sound file Height=16 and width=240 so that the user only see the controller bar

Hiding QuickTime sounds Creates background music  Same as adding just sound except  In object  In embed Load the sound at the end of your xHTML file  Visitors can look at page while waiting for the sound

Embedding Windows Media Player files Almost the same as QuickTime  Different classid  Different parameters

Windows Media for embed <embed type="application/x-mplayer2" pluginspage=" dows/MediaPlayer/" src="madmax.avi" width="240" height="252" autostart="0" showcontrols="1" showstatusbar="1">

Inserting Java Applets Find an applet (something.class) Only has object (no embed) multimedia/javaobject.html

Embedding Other Multimedia Files Go the web site of the company the develops the player for the file you are interested in Look for developer sections  Classid info  Param info

Linking to Multimedia files One way of including Multimedia files is to link them instead of imbedded  file  If the user has the right plugin the file will play in a new window  If the user doesn’t have the plugin, the file will be open in an external player  If the user doesn’t have a plugin or player then they can download the file

Creating a Automatic Slide Show You can create a xHTML page that loads another page after a predetermined time interval  Within the head section N is number of seconds till next page is loaded

Example Page 1 Page 2 Page 3 Page 4 STOP

Adding a background sound Works in IE only   N can be A number “-1” or “infinite” for continuous looping  Can only sound file of the following types.wav.au.mp3.mid multimedia/bgsound.html multimedia/bgsound.html
