To configure a pull (RTSP) input:
Objective: Pull an RTSP unicast RTP stream(s) from a source as input to the DME. If the
stream is coming from an external server, like a Vbrick H264 encoder, follow steps 1 and 2,
and 3. Otherwise the stream should be active and available either from another DME, or
internally from the same DME, and you can start at Step 4.
1. In the encoder, set the desired Audio/Video configuration for frame rate, resolution,
video and audio rate, sampling frequency etc.
2. In the encoder, select a stream to send, set the stream type to RTP, and select the streams
you want to send to the DME (including audio, video, or both).
3. In the encoder, select the resource name of the stream to be used in the server
component of the encoder. The default name for streams served from the encoder is
vbStream1S1. You can change the name to anything you want. You also need to enable
the server.
4. In the DME, launch the management interface, log in, and go to System Configuration >
Flash/RTSP Pull Settings. You will need to pull an RTSP stream from a source, so find
an open slot from the 25 possible slots and select RTSP as the type. Enter the server IP
address or DNS host name, and enter the port if not already 554 (default port for RTSP).
Since this is RTSP, no entry for Application is required. Enter the publishing point name
like vbStream1S1. If you are pulling a stream specified in use case
In-8 < Unicast/
Multicast RTP or In-3 < RTP Auto Unicast, enter the sdp filename used when creating
the stream. In most cases there will no need for the user name and password since this is
a pull. Note: the pull uses RTSP Interleaved streams delivered by TCP only so make sure
this is supported on the source.
5. If you know the RTSP source does not generate RTCP reports, or the RTCP reports do
not have accurate time sync information, uncheck the Use RTCP box and the DME will
not look for RTCP reports or ignore those coming in. Note: RTCP reports help to
enable audio and video sync. If unchecked, there will be no way to "re-sync" the stream
Application Only required if you are pulling RTMP from an RTMP server such as
another DME or an FMS. See
In-5 < Pull (RTMP). This string is
defined by the source.
Publishing Point This is the
Resource Name on the Program Configuration > Servers
page on the encoder.
Stream Name User-friendly name displayed on the DME. Used, for example, to
simplify cryptic publishing point names coming from a CDN. This
name becomes the incoming stream name the DME uses to distribute
the stream in multiple ways.
User Name If the incoming stream requires authentication, enter the user name
and password.
Password If the incoming stream requires authentication, enter the user name
and password.
Use RTCP Lets you use RTCP sync reports for the incoming stream. If you know
your source does not produce RTCP reports, uncheck this box.
Status Displays the high-level status (Disabled | Connected | Receiving) of
the incoming stream.
