Chapter7 Cisco Hinte r for RTSP
Concepts
Cisco Hinter versions for Windows and Linux users are downloadable from your DMM appliance.
Note We do not develop, maintain, sell, or support Darwin Streaming Server. Nor do we warrant its suitability for any purpose.
Workflow
1.
Download and set up Cisco Hinter.
2.
Download Darwin Streaming Server (DSS).
Note The official repository for DSS is http://dss.macforge.org. Alternatively, you can use
http://developer.apple.com/opensource/server/streaming/index.html.
3.
Install and configure DSS on equipment other than any CiscoDMS server appliance.
4.
Process each of your MPG files with Cisco Hinter to output a small, hinted MOV file.
5.
Stage your MPG and MOV files together in the DSS serving directory.
6.
Request streams from rtsp://<DSS_IP_address>:<optional_port_number>/<filename>.mov.

Restrictions
RTSP Variants
•
There are many variants of RTSP and we support only one of them. You must use RTP over RTSP,
which is also called RTP over TCP or Interleaved TCP. In this variant, RTP, RTCP, and RTSP data
stream together over one logical port—typically, port 554.
•
Our RTSP does not support live streaming (multicast or unicast) in this release.
•
Our RTSP does not support “trick mode.” This means that you cannot pause video during playback,
fast-forward through it, or fast-rewind through it. You can merely start or stop playback.
Darwin Streaming Server
•
DSS cannot read any file whose file size is greater than 2.1 GB. You must split such large files into
smaller ones before you derive hinted MOV output from them. (CSCtb27324)
•
Although DSS is an open source streaming media platform and available for multiple operating
systems, we have tested DSS on Linux exclusively.
