14.9. Recording and Publishing Video and Audio

Problem

You want to record video and/or audio from a Flash movie and publish it to a FlashCom server.

Solution

Create a net stream, attach the video using attachVideo( ), and attach the audio using attachAudio( ). Then call the NetStream.publish( ) method and specify “record” or “append” as the recording mode.

Discussion

To use a net stream object to record and publish video and/or audio to a FlashCom server, follow these steps:

1. Establish a net connection:

   myConnection = new NetConnection(  );

2. Connect to the FlashCom server:

   myConnection.connect("rtmp:/myApplication/");

3. Create the net stream:

   publishRecorded_ns = new NetStream(myConnection);

4. Attach the audio and/or video to the net stream using the attachAudio( ) and/or attachVideo( ) method:

   myMic_mic = Microphone.get(  );
   myCam_cam = Camera.get(  );
   publishRecorded_ns.attachAudio(myMic_mic);
   publishRecorded_ns.attachVideo(myCam_cam);

5. Use NetStream.publish( ) to record the stream on the server. The first parameter is the name by which the stream should be known by the FlashCom application (when a client wants to subscribe to it, for example). The second parameter is the recording mode. If you specify “record” as the recording mode, any existing stream of the same name (within the FlashCom application) is overwritten. If you specify “append” as the recording mode, the new stream data is appended to any existing stream of the same name (a new stream is created on the server if none exists).

   publishRecorded_ns.publish("myFirstStream", ...
