What is Streaming Media?

RealMedia clips created by RealProducer are streaming audio and video presentations, also known separately as RealAudio and RealVideo. Prior to RealMedia, one had to wait for a media file to download in order to play it. When you create a streaming clip, users can play it almost instantly. Plus, you can stream live media, enabling you to send your content directly to your audience. By streaming a clip, you are sending small packets of information over a connection. On the other end, the user receives the information and plays your media clip bit by bit. The process is almost invisible to the user, except for a small amount of initial buffering.  RealProducer G2 is an integral part of the RealNetworks RealSystem G2. RealProducer creates the clips, RealServer™ sends the clips, and RealPlayer™ shows the clips. You can also use an Internet server to stream files, but you need to use a RealServer to stream live content.

The RealProducer Main Window

Before you begin to create RealMedia content, let's briefly tour the different components of the RealProducer main window. This window is where you create, start, view, and stop a recording session.  

The RealProducer Main Window

The upper section of the window is where you monitor the recording process. "Viewers" show you the input video and the recorded output during a recording session. Meanwhile, an audio level indicator gives you a visual representation of the audio track.  The middle section lists all necessary information about the final RealMedia file. Details such as clip information, the target audience, and the type of stream being recorded are found here. On the bottom are the recording controls. These controls allow you start, stop, and play the current recording session. Also located here are the publishing controls. They are explained in "Publishing to the Internet".

Creating Streaming Media

RealProducer includes a number of simple wizards to guide you step-by-step through the recording process. These recording wizards are specifically designed to:  convert existing audio and video files into RealMedia files record RealMedia files from media capture devices broadcast live, streaming content using a RealServer If you are more familiar with the recording process, you can bypass the wizards and set up the recording process manually. This option is discussed later in this chapter.

Recording from Media Files

This section describes how to record a RealMedia file from different types of existing media files using the recording wizard.  Only the following audio and video formats can be converted into RealMedia clips using the RealProducer:

Audio (.au)

Waveform audio (.wav)

Video for Windows (.avi)

QuickTime for Windows (.mov); requires DirectX 6.0
