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. 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.
connect <instance_name>: Build a connection to receiver named instance_name. All connectable receivers are discovered by discovery module and printed in the output log.avail <url>: Begin listening for all connected receivers that support the presentation of url.start <url> <instance_name>: Start a presentation of url on the receiver specified by the instance_name. instance_name 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: Terminate the running presentation.
