  • ARTDM 171, Week 14: Multimedia on the Web

    1. 1. ARTDM 171, Week 14: Multimedia on the Web Gilbert Guerrero gguerrero@dvc.edu gilbertguerrero.com/blog/artdm-171/
    2. 2. Homework • Put your homework in my dropbox • Put them in a folder with your lastname and first initial • Example: smith-h contact
    3. 3. Multimedia
    4. 4. Plug-ins • The Web was designed to display text and include images • These are the “native” formats of the Web • Everything else is only viewable on the Web through a plug-in
    5. 5. Significant and Problematic Although plug-ins significantly expand the possibilities of the Web, theyʼre equally problematic •Compatibility with Browsers and OS •Must have the right plug-in to view, or the most up- to-date plug-in if it changes often •Not centrally controlled or standardized •Security concerns, since software will be installed on your usersʼ computers •More sophisticated coding to use them, with specific parameters and languages for each
    6. 6. Eolas patent • Microsoft was sued by the Eolas company which held a patent on technology to play media automatically • Microsoft changed Internet Explorer to stop playing media automatically, including Flash • Click here to activate message appeared before users could interact with all multimedia • The Workaround: load multimedia dynamically using JavaScript • Dreamweaver automatically adds the JavaScript whenever you add Flash to a page
    7. 7. Codecs • Compression-Decompression, or Code- Decode • Source files are not viewable on the Web • Your editing software compresses and encodes your source files with codecs • Plug-ins decompress and decode your multimedia files to make them viewable to your users • Some plug-ins can read multiple formats, not all of them can  
    8. 8. Common codecs and formats Video: •Flash Video, .flv •Windows Media, .wmv •AVI (Audio Video Interleave), .avi •MPEG, .mpg or mpeg •MP4, .mp4 •Quicktime, .mov •RealVideo, .rm or .ram •IPod, .m4v Audio: •MP3, .mp3
    9. 9. Design considerations • Donʼt surprise your users with multimedia • Present media on a secondary page • Use a fast loading plain HTML page as the main page to present users with information and a screenshot or preview • Include the running time, format, and file size • Explain any special software requirements and provide a download link to required browser plug-ins • Provide playback controls • Make viewing your multimedia a user choice, allow your users to confirm their systems are properly configured and that they have enough bandwidth, time, and patience to continue Further reading, Web Style Guide: Multimedia
    10. 10. Embedding a Flash Video
    11. 11. FLV - Flash Video format • Flash is the most widely used plug-in on the Web right now.  98% penetration, more than WMV and Quicktime • Just drag and drop, or: ‣ Select Insert > Media > Flash Video ‣ For other types of media, go to Insert > Media > Plug-in • Select a player skin • Upload all files to server
    12. 12. More about embedding Flash • Bye Bye Embed by Elizabeth Castro, A List Apart  • Flash Embedding Cage Match by Bobby van der Sluis, A List Apart
    13. 13. Other Flash Video Players (skins) If you're not excited about Dreamweaver's skins, you can: •Build your own •Download one someone else has built ‣ JW FLV Media Player
    14. 14. Inserting Flash
    15. 15. SimpleViewer • SimpleViewer is a Flash movie that can pull images and thumbnails from a folder and show them in a slideshow • Use the Manual Instructions for the most control
    16. 16. JavaScript Slideshows
    17. 17. Coda-Slider • Coda-Slider uses JavaScript, HTML, and CSS to create a tabbed slideshow • This alternative works where you donʼt want to or canʼt use Flash
