AXIS 247S - Video and Audio Streams
9
Other methods of accessing the video stream
Video/images from the Video Server can also be accessed in the following ways:
• If supported by the client, the Video Server can use Motion JPEG server push to display video. This
option maintains an open HTTP connection to the browser and sends data as and when required, for
as long as required.
• As single JPEG images in a browser. Enter e.g. the path: http://<ip>/axis-cgi/jpg/image.cgi?resolu-
tion=CIF
• Windows Media Player. This requires AMC and the MPEG-4 decoder to be installed. The paths that
can be used are listed below, in the order of preference.
• Unicast via RTP: axrtpu://<ip>/mpeg4/#/media.amp
• Unicast via RTSP: axrtsp://<ip>/mpeg4/#/media.amp
• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<ip>/mpeg4/#/media.amp
• Unicast via RTSP, tunneled via HTTPS: axrtsphttps://<ip>/mpeg4/#/media.amp
• Multicast: axrtpm://<ip>/mpeg4/#/media.amp
Notes: • <ip> = IP address.
• # = video source number. This is set to 1 if omitted.
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, e.g. QuickTime™ the Video Object Type must be set to Simple. It may also be necessary
to adjust the advanced MPEG-4 settings.
To assess 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 Video Server to determine exactly
which transport protocol to use.
Notes: • <ip> = IP address.
• # = video source number. 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 product sends synchronization information along with the
streams to the client that is 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 Video Server can also be
accessed in the following ways:
