Tutorial : HTML Multimedia

What is Multimedia?

Multimedia comes in many different formats. It can be almost anything you can hear or see like text, pictures, music, sound, videos, records, films, animations, and more. On the Internet you can often find multimedia elements embedded in web pages, and modern web browsers have support for a number of multimedia formats.

In this tutorial you will learn about different multimedia formats and how to use them in your web pages.

Browser Support
The first Internet browsers had support for text only, and even the text support was limited to a single font in a single color. Then came browsers with support for colors, fonts and text styles, and the support for pictures was added.

The support for sounds, animations and videos is handled in different ways by different browsers. Some elements can be handled inline, and some requires an extra helper program (a plug-in).

Multimedia File Formats  :

Multimedia elements (like sounds or videos) are stored in media files.
The most common way to discover the media type is to look at the file extension. When a browser sees the file extensions .htm or .html, it will assume that the file is an HTML page. The .xml extension indicates an XML file, and the .css extension indicates a style sheet. Picture formats are recognized by extensions like .gif and .jpg.

Multimedia elements also have their own file formats with different extensions like .swf, .wmv, .mp3, and .mp4.

Video File Formats :
     
   The MP4 format is the new and upcoming format for internet video. It is supported by YouTube, Flash players and HTML5.
                                         

Format        File         Description
AVI              .avi         The AVI (Audio Video Interleave) format was developed by Microsoft. The AVI format is supported by all   
                                      computers  running Windows, and by all the most popular web browsers. It is a very common format on   
                                      the Internet, but not always possible to play on non-Windows computers.

WMV   .wmv         The Windows Media format is developed by Microsoft. Windows Media is a common format on the Internet, but
                                      Windows Media movies cannot be played on non-Windows computer without an extra (free) component   
                                      installed.
                                      Some later Windows Media movies cannot play at all on non-Windows computers because no player is
                                      available.

MPEG  .mpg .mpeg         The MPEG (Moving Pictures Expert Group) format is the most popular format on the Internet. It is cross-
                                      platform and supported by all the most popular web browsers.

QuickTime      .mov         The QuickTime format is developed by Apple. QuickTime is a common format on the Internet, but QuickTime   
                                      movies cannot be played on a Windows computer without an extra (free) component installed.

RealVideo     .rm .ram       The RealVideo format was developed for the Internet by Real Media. The format allows streaming of video
                                      (on-line video, Internet TV) with low bandwidths. Because of the low bandwidth priority, quality is often
                                       reduced.

Flash   .swf  .flv         The Flash (Shockwave) format was developed by Macromedia. The Shockwave format requires an extra
                                      component to play. But this component comes preinstalled with web browsers like Firefox and Internet
                                      Explorer.
 
Mpeg-4   .mp4           Mpeg-4 (with H.264 video compression) is the new format for the internet. In fact, YouTube recommends using
                                      MP4. YouTube accepts multiple formats, and then converts them all to .flv or .mp4 for distribution. More and
                                      more online video publishers are moving to MP4 as the internet sharing format for both Flash players and
                                      HTML5.

Nice post sir. If you want to convert your file to other file formats then use winFF or FFMPEG tool.
