HTTP Streaming RealAudio and RealVideo Files

Note: Now that RealNetworks offers a free license for their RealServer, there is little reason for streaming RealAudio and RealVideo. Instead, you should install the RealNetworks RealServer and "serve" the RealAudio/RealVideo content rather than "stream" the content (which is what is explained below).

Many virtual server users want to offer RealAudio and RealVideo streams but do not want to pay for a RealAudio/Video server that streams these files. Streaming files means that the RealAudio and RealVideo files begin playing before the entire file is downloaded. RealAudio and RealVideo files can be quite large and many people surfing the web would not wait to see the entire file download before it started playing.

A RealAudio/Video server allows you to offer these streamed files. However, you can also stream these files without the RealAudio/Video server. It isn't quite as nice as using the server, but it will cost you no money. It is known as HTTP Streaming.

To stream RealAudio and RealVideo content using HTTP from your BWSD AW Virtual Server:

	First, you need to add the following two lines to your www/conf/mime.types file: audio/x-pn-realaudio rm ra ram audio/x-pn-realaudio-plugin rpm If you choose to FTP this file and edit it on your local machine with a text editor (such as notepad), be sure you FTP it in ASCII mode as it is a text file.
	Second, copy your encoded RealAudio and RealVideo files (files with the .rm and .ra extensions) to your Virtual Server using FTP. Be sure to FTP these files in Binary mode.
	Third, use a text editor to create a metafile containing a RealAudio or RealVideo URL. For example, the contents of your file should be in the following form:     http://hostname/path/filename where hostname is the name of your World Wide Web server. For example:     http://www.your-domain.name/path/filename.rm
	Fourth, save the above metafile as a text file with the .ram extension. For example:     filename.ram Then FTP this file to your virtual server in ASCII mode (because it is a text file).
	Fifth, in your HTML document, reference the metafile in a hyperlink. For example:     <A HREF=&quotfilename.ram">     <A HREF="http://www.your-domain.name/path/filename.ram"> You can use relative or complete paths. If you use complete paths, you must include both the hostname and the complete path.
	Last, when a user clicks on the link, the audio/video file(s) begin to download. The RealPlayer begins playing after a few seconds; it does not need to wait for the entire file to be downloaded.
