sdr-launch - Session Directory Client Launcher
/var/netscape/communicator/sdr-launch
sdr-launch is a HTTP helper application that is launched on the client
system through the use of the .sdr mime typeextension. This application
parses the session directory announcement sent by the Web Server and
after consulting the transformations file (mbone-fmt.txt) launches the
appropriate media tool for audio, video, whiteboard announcements.
Operation [Toc] [Back]
The format of the mbone-fmt.txt file is as follows:
Each line consists a announcement media`format' field. Each one of these
fields can be followed by 3 other fields specifying (1) name of the
application to launch for playing that format, (2) full path of the
application, and (3) the complete set of command line options in the
application specific syntax for that application.
There is also a line each provided for the `default-audio', `defaultradio',
`default-video', and `default-wb'. These `default' entries are
used in the transformation if either the specified media format is not
found in the file or is empty.
Currently the following attributes are available for use in the
application command line options.
ttl Time to Live value of the announcement
format media format
multicast Multicast Address of the announcement
address
port Port number of the announcement
multicast ID Multicast ID of the announcement, this is
sometimes used by some of the applications
Each one of these options need to be prefixed with a `+', this tells the
launcher that it needs to stuff actual values for them.
