Use the following table to configure the output analog digital settings for an MPEG4 encoder.

Note: This tab is dynamic depending upon which encoder you select on the Video tab. The choices in

the drop-down list may vary.

To configure output settings:

Select Enable Streaming to stream your audiovisual content via RTSP.

Set the appropriate streaming properties.

Note: The default settings will enable multicast streaming. If you do not want this type of

streaming, change the IP address for Group to the IP address of the server to which you

want to stream from the encoder.

In the SDP File field, enter a name and a destination path for the resulting SDP file created

when you start the stream. If you are streaming to a Helix, a QuickTime, or a Darwin server,

refer to its respective documentation or online message boards for setup details specific for

the individual streaming server.

Note: You can stream point-to-point by selecting a share destination directory for the saved

SDP file. Remember to disable multicasting by entering in the IP address of the PC to

which you want to stream.

For example, if you want another PC to view the stream, save the SDP file to a share

folder on the local drive. The other PC can open the SDP file and the stream can be

played in a QuickTime or other MPEG-4 compatible streaming player. Since MPEG-4

encoding can be CPU intensive, it is not recommended that you view the stream on the

Niagara encoder. Doing so may overtax the host CPU, which will cause video quality

degradation and encode session failure.

Select Save to File to save the encoded content to a file. Each time you start this encoder,

the system overwrites the previous file.
