This directory contains a demo of a Presentation API controller and receiver. The demo supports flinging a URL to start a presentation and stopping the presentation.
The same executable is run for the controller and receiver; only the command line options affect the behavior. The command line options are:
$ osp_demo [-v] [friendly_name]
-v
enables verbose logging.friendly_name
puts the demo in receiver mode and sets its name to friendly_name
. Currently, friendly_name
won't appear in any of the controller-side output related to this screen though. If no friendly name is given, the demo runs as a controller.Because the demo acts like a shell and accepts commands on stdin
, the logging output is redirected to a separate file so it doesn't flood the same display. You have to create these files on your machine before running the demo. For the controller, this file should be named _cntl_fifo
and for the receiver, it should be named _recv_fifo
. The simplest way to do this is so you can see the output while the demo is running is to make these named pipes like so:
$ mkfifo _cntl_fifo _recv_fifo
Then cat
them in separate terminals while the demo is running.
avail <url>
: Begin listening for receivers that support the presentation of url
.start <url> <service_id>
: Start a presentation of url
on the receiver specified by the ID service_id
. service_id
will be printed in the output log once avail
has been run. The demo only supports starting one presentation at a time.msg <string>
: Sends a string message on the open presentation connection.close
: Close the open presentation connection without terminating the presentation.reconnect
: Reconnect the previously-connected presentation connection. This allows using the msg
command again.term
: Terminate the previously started presentation.avail
: Toggle whether the receiver is publishing itself as an available screen. The receiver starts in the publishing state.close
: Close the open presentation connection without terminating the presentation.msg <string>
: Sends a string message on the open presentation connection.term
