16AXIS 241QA/AXIS 241SA - Video and audio streams

Other MPEG-4 clients

Although it may be possible to use other clients to view the MPEG-4 stream, it is not guaranteed to work in all cases. For some other clients, such as QuickTime™ the Video Object Type must be set to Simple. It may also be necessary to adjust the advanced MPEG-4 settings.

To access the video stream from e.g. QuickTime™ the following path can be used:

rtsp://<ip>/mpeg4/#/media.amp

This path is for all supported methods, and the client will negotiate with the AXIS 241QA/AXIS 241SA to determine exactly which transport protocol to use.

Notes:

•

<ip> = IP address.

 

•

# = video source number or the quad stream. This is set to 1 if omitted.

Audio transmission methods

The audio stream can be accessed in the Live View page when viewing either Motion JPEG or MPEG-4.

Using Motion JPEG

The basic transmission method of audio used in conjunction with Motion JPEG video streaming is transmission over HTTP. The video and audio streams are not synchronized when using Motion JPEG so the streams may be slightly out of sync. The latency in any stream should be low, but this will depend on the network infrastructure.

Using MPEG-4

When using MPEG-4, audio is streamed using the same protocol as the video stream.

When audio is transmitted using MPEG-4, the Axis video server sends synchronization information along with the streams to the client performing the synchronization.

Note: Audio is streamed from the client to the server over HTTP when using Motion JPEG and MPEG-4.

Accessing the audio streams

In addition to accessing audio in the Live View page using AMC, audio from the AXIS 241QA/AXIS 241SA can also be accessed in the following ways:

AXIS VAPIX API

You can read about accessing audio for the other protocols through the VAPIX® API at www.axis.com/techsup

QuickTime/Windows Media Player

It is possible to use QuickTime and Windows Media Player to listen to the audio stream using the same methods to access video streams.

Java Applet

The Java applet supports simplex audio.
