The following Windows Media Tools depend on other hardware and software to function correctly. Make sure you have met these requirements before attempting to use the tool.
To encode live content, the computer on which you install Windows Media Encoder must contain:
You do not need either of these cards to encode an .avi, .wav, or .mp3 file to an .asf file.
The input jacks on the audio and video cards receive the live data and then transmit it to Windows Media Encoder. For example, to multicast a live speech, you must plug the output from a video camera into the input jack on the video card and plug the output from the microphone into either the audio input jack on the video card or the input jack on the sound card (whichever card the encoder is going to use). The encoder acknowledges these input sources, receives the input, and encodes the audio and video into an ASF stream that is then delivered to a Windows Media server.
If you are planning to use multiple bit rate video to encode live content at multiple bandwidths, your encoding computer's processor must meet the following minimum requirements:
For the best results when encoding live content at multiple bandwidths, the following processors are recommended:
If you plan to use Windows Media ASF Indexer to add indexes, markers, script commands, and properties to existing .asf files, you must install Microsoft Windows Media Player. Windows Media Player is also necessary to render ASF content.
