RealPlayer lets you stream video and audio files directly from the Internet to your desktop, eliminating the often long delay incurred by having to download an entire file before you can begin playing it. Just double-click on an A/V file in a Web site; this opens a RealPlayer window that plays the file on your desktop. If you have files already downloaded, you can drop them on the RealPlayer icon to open a window and play them.
RealPlayer supports various real video and audio file types, along with mp3 and mpeg audio. For a complete list of supported file types, right-click on the real icon and choose Add-ons > FileType from the context menu; in the middle of the window that appears you'll see a scrolling list of supported file types.
You can play video with audio or audio alone on RealPlayer. The window you'll see--with or without a viewing screen--depends on the file you choose to play, although the controls are the same for both windows. In the top of the two bars at the bottom left of the window are, from left to right:
Lower bar indicators, from left to right:
The video window has a resizable screen--just grab the lower-right corner and drag it out.
The menus duplicate some of the window's manual controls and also give you access to Preferences, Statistics, and this Help file.
The File menu has an Open command that lets you open a previously downloaded file via a selection window. Additionally, you can Pause, Stop, and Quit a file by selecting from the menu or using the appropriate keyboard command.
Two View menu commands, Original Size and Double Size, let you set the RealPlayer viewing area in two standard sizes; for finer control you'll want to use the resize feature in the window's lower-right corner.
Preferences. The two protocol settings--Use RTSP proxy and Use HTTP proxy --may apply if you are operating outside a server's firewall. Some servers require you to enable a proxy to access the server. If this is true for you, ask your network administrator how to set the proxies. The bandwidth settings range from 14.4 modem to 10 Mbps LAN. Normal bandwidth reflects the bandwidth of your current download; many servers will scale this bandwidth automatically. Maximum bandwidth is the maximum capacity allowed by your server connection, so your setting may not exceed that maximum; for example, if you have a T1 line, set it for T1.
Statistics shows you the current download rate. Under the Bandwidth heading, if the Encoded at number is higher than the Average download number, you'll get skips in your download as it streams. If that happens, refer to these numbers to reset your bandwidth preferences. The Packets numbers show you the progress of information received as packets in your download.
The Help menu's Contents command brings up this brief descriptive guide to using RealPlayer.
