Example

This is an example of a web streaming script:

The following examples implement the basic streaming flow skeleton:Play the movie from the beginning (the entire movie duration is XXX).
web.streamPlay( { id : n, playingDuration : XXX } );Pause the movie.
web.streamPause( { id : n, pausingDuration : XXX } );Stop the movie.
web.streamStop( { id : n } ); HTTPfunction Action(){    //Open an HTTP stream
    web.streamOpen(
        {
            id : 1,
            url : 'http://myhost/streaming-test/video/tiny.mp4',
            protocol : 'HTTP'
        }
    );    //Play for 10s
    web.streamPlay( { id : 1, playingDuration : 10 } );
        //Pause for 5s
    web.streamPause( { id : 1, pausingDuration : 5 } );
        //Seek to 00:00:20
    web.streamSeek( { id : 1, timeOffset : 20 } );    //Change the speed to 1.5
    web.streamSetParamDouble('1',web.SPEED, 1.5);    //Play for 10s
    web.streamPlay( { id : 1, playingDuration : 10 } );    //Get bytes received
    var bytes = web.streamGetParamInt('1',web.BYTES_RECEIVED);    //Close streaming
    web.streamClose(
        {
            id : 1
        }
    );     return 0;
