View Course Outline
  • Lesson 1: Adding Cue Points with ActionScript
    Some videos come with cue points embedded in them, but sometimes the videos don't. In this lesson we learn how to add cue points to videos in Flash, dynamically, with ActionScript -- so that you can use cue point functionality even with videos that do not have cue points.
    • Understanding and Using FLVPlayback.addASCuePoint()
    • Building an Array of CuePoints
    • Importing the MetadataEvent
    • Hearing the MetadataEvent.CUE_POINT Event
    • Adding the Cue Points to the Video
    • Reacting to the Cue Point Data
  • Lesson 2: Building a Closed Captioning System
    While you could use cue points to build closed-captioning into your video players, you don't have to. Because Flash comes with support for the Timed Text Tags standard, and makes it possible to build closed-captioning into your video players in under a minute, with almost no code. In this lesson, we learn how.
    • Why Use Captioning
    • Adobe's Implementation of the Timed Text Tags XML Standard
    • The FLVPlaybackCaptioning Component
    • The CaptionButton Component
    • Burning Captions into Your Video with Captionate
  • Lesson 3: Using Cue Points for Navigation
    Cue points can be used for various purposes. In this lesson we learn how to use cue points to implement chapter markers, or bookmarks, in our videos, to make it easy for viewers to jump around our content.
    • Working with 'Navigation' Cue Points
    • Listening for the MetadataEvent.METADATA_RECEIVED Event
    • Seeking Video By Cue Point
  • Lesson 4: The Basics of Working with the Webcam in AS3
    Of course, Flash comes with support for webcams. While it does require ActionScript, it's actually really not all that difficult to start working with webcams in your Flash movies. In this lesson, we learn the core code to work with the webcam, and handle situations where users do not have webcams, or choose to deny you access to them.
  • Lesson 5: Motion Detection with the Webcam in AS3
    While executing operations like image analysis and pattern detection in webcam feeds is some pretty advanced stuff, implementing a motion detection system on a webcam feed is incredibly easy. In this lesson, we learn how to use motion detection with the Camera object in Flash.
    • The ActivityEvent.ACTIVITY Event
    • The ActivityEvent.activityLevel Property
    • Killing and Cleaning Up Your Webcam Instance
