4 In the initStreams function, make a connection to the server. Create the output stream for

sending the video data to the server, and the input stream for the data coming back from the

server. Then attach the input stream to the

Replay_video video clip.

function initStreams() {

// Make a connection to the application on the server

client_nc = new NetConnection();

// Note that this call includes the protocol, rtmp, the

// app name, doc_record, and the room, room_01

client_nc.connect("rtmp:/doc_record/room_01");

// Handle status message

client_nc.onStatus = function(info) {

trace("Level: " + info.level + " Code: " + info.code);

}

// Create output stream

out_ns = new NetStream(client_nc);

// Create input stream

in_ns = new NetStream(client_nc);

Replay_video.attachVideo(in_ns);

}

// Connect to server and set up streams

initStreams();

Create the event handler for the Record button. If the user selected the button when the label

was Record, then attach video data from the camera to the output stream and publish it. If the

button label is Stop, close the stream.

function doRecord() {

if (Record_btn.getLabel() == "Record") {

// Start publishing the camera output as a recorded stream

out_ns.attachVideo(Camera.get());

out_ns.publish("my_recorded_stream", "record");

// Don’t allow the user to play when recording

Play_btn.setEnabled(false);

// Change the button label

Record_btn.setLabel("Stop");

} else if (Record_btn.getLabel() == "Stop") {

// Close output stream

out_ns.close();

// Now that you’re finished recording, allow the user to play

Play_btn.setEnabled(true);

// Change the button label

Record_btn.setLabel("Record");

}
