OPTICODEC-PC
STREAMING SERVERS
4-5
rtsp://dss.server.ip.address/sample_100kbit.mp4
where
dss.server.ip.address
is the IP address or hostname of DSS.
The test file should play the QuickTime logo with audio and video.
The supplied test files will not work with RealPlayer, as they are in an un-
supported format.
Security: Access and Authentication
A certain level of security is inherent in real-time streaming because content is deliv-
ered only as the client player needs it and no media files remain afterwards. How-
ever, you should address other security issues. These include access control for en-
coders and client players, if needed.
By default, DSS has no authentication configured for encoder-server connections.
There are two encoder-server configurations that determine access and/or authenti-
cation to allow you to create the session description protocol file (.sdp file) required
for live streams. The .sdp file provides information about the format, timing, and
authorship. DSS access and authentication are configured using text files, called ac-
cess files, in very much the same way that an Apache web server is configured.
DSS access and authentication are not configured using the DSS Remote
Administration browser interface.
DSS can also be configured to control client player access to live streams as well as
streamed media files. Currently, only QuickTime Player 6 above supports this;
RealPlayer 10 does not.
For access control to work, an access file must be present in the DSS media directory.
If an access file is not present, all player clients are allowed to access the media and
live streams in the directory, and all encoders on other computers will have no write
access and thus will not connect.
Different encoder-server configurations require slightly different setups:
Opticodec-PC Encoder and DSS on the Same Computer
Any encoder running on the same computer as DSS can connect without authentica-
tion. DSS does not require or use authentication in this configuration. A Username
and Password are not required for the encoder to have write access to create the
.sdp file in the media directory, and therefore no further configuration is necessary.
