Out-4 > Serve (Rtp) - VBrick dme Admin Manual

The RTP server on the DME serves RTP files. Play the stream in StreamPlayer, QuickTime,
or VLC using a URL similar to this:
rtsp://server:port/publishing_point.sdp
Since the Multi Protocol RTP server uses an non-standard RTSP port – default 5544 – normally
the port must be explicitly included in the URL.
To configure a serve (RTP) output:

Objective: This use case explains how a stream available on the Multi Protocol server is
served to clients that support RTSP streams. Further, this server is commonly used for
delivering VOD content.
From a client that supports RTSP RTP streams, enter the RTSP URL, typically:
rtsp:// DME_ip_address:5544/streamname

The RTP server on the DME serves live or stored content using the RTSP/RTP protocol.
You can play the stream in StreamPlayer, QuickTime, or VLC using a URL similar to this:
rtsp://server:port/<publishing_point>
Normally the default port 554 is assigned to the RTSP/RTP server, so the port number is
optional in the URL. If an alternate port is assigned to the RTSP/RTP server, then the port
number must be entered. There are two use cases for serving RTSP. Out-4 should be used for
optimal stream stability, but if many simultaneous users are expected, the equivalent Out-3 is
preferred. There are three possible protocols used for RTP serving: UDP; TCP using RTSP
interleaved; TCP using HTTP tunneling. Out-4 supports all three of these options while
Out-3 does not support HTTP tunneling. This difference may affect which RTSP/RTP
server to use.
Live
Note that this output option requires no explicit configuration on the DME but is available
for all live content present on the RTP streaming server, whether brought directly into the
RTP server or Pushed from the Multi Protocol server using an internal Out-10. A live
publishing point includes the ".sdp" extension in the publishing point name so an example of
a live publishing point is:
rtsp://<dme_ip_address>/my_streamname.sdp
Stored
There are two options for serving RTSP. Out-4 must be used if the VOD content contains
MPEG-4 Part2 video or PCM audio. Stored content is accessed using the filename of the
content. Examples of stored URLs are:
rtsp://<dme_ip_address>/filename.mov
rtsp://<dme_ip_address>/filename.mp4
