URLs
Add/Modify a URL for a Live Video Stream
Administrators can manually enter URLs to live video streams that will not automatically be
displayed by the Portal Server. For example, the administrator may wish to have the
Announcements (SAPs) disabled on the VBrick encoders for security purposes. Or the
Administrator may want to enter the address of an off-network stream such as an MPEG-4
Stream from an Apple Darwin Server or a stream coming from a hosting provider.
Additionally, this feature lets you enter the addresses of non-MPEG streams such as
Windows Media and Real Networks. Note that the Access Control feature Allow Viewing by
Content Type does not apply to manually added URLs.
The following examples show valid URL syntax for live video streams. All URLs are case
sensitive. The syntax must be accurate and there is no internal validation of user input:
Valid for Types MPEG-1 and MPEG-2
vbricksys://ip=239.1.1.1&port=4444
Where
239.1.1.1
is the multicast IP address and
4444
is the multicast port.
Valid for Type MPEG-4
rtsp://172.1.1.1/vbrickvideo1
vbrtsp://172.1.1.1/vbrickvideo1
Where
172.1.1.1
is the source IP address and
vbrickvideo1
is the program name.
vbhttp://172.1.1.1/vbs2d1.sdp
Where
172.1.1.1
is the source IP address and
vbs2d1.sdp
is the SDP file name.
Valid for Type Other
ASX Files
http://172.1.1.1/file.asx
Note For any non-MPEG video, the correct player (such as Windows Media Player or Real
Player) must be present on the desktop for the client to be able to receive the stream.
Set Top Boxes will not be able to receive non-MPEG streams because the Set Top
Box only includes decoders for MPEG-1, MPEG-2, and MPEG-4.
