The video object

‣ The most basic simple code to playback video in Flash:var nc:NetConnection = new NetConnection();

nc.connect(null);

var ns = new NetStream(nc);

myVideo.attachVideo(ns);

ns.play("yourVideo.flv");

14

‣Or, for streaming video:var nc:NetConnection = new NetConnection();

nc.connect("rtmp://yourFMSserver.com/yourAppName/yourInstanceName");var ns = new NetStream(nc);

myVideo.attachVideo(ns);

ns.play("yourVideo.flv");

Demystifying metadata and cue points

‣What are they?

‣Or, in some cases external (ActionScript cue points)

‣How do they differ?

‣Metadata: single values

‣Cue points: Associative array of cue point objects

‣What you’d use them for
