The external playlist.xml file specifies which videos to load, and the order to play them back in. In order to load the XML file, you need to use a URLLoader object and a URLRequest object, as seen in the following code:

This code is placed in the VideoJukebox class's constructor so the file is loaded before any other code is run. Ms word for macbook. As soon as the XML file has finished loading, the xmlCompleteHandler() method is called which parses the external file into an XML object, as seen in the following code:

The playlist XML object contains the raw XML from the external file, whereas the videos XML is an XMLList object which contains just the video nodes. A sample playlist.xml file can be seen in the following snippet:

Finally, the xmlCompleteHandler() method calls the main() method which sets up the various component instances on the display list, as well as the NetConnection and NetStream objects which are used to load the external FLV files.

To build the user interface you need to drag five Button instances onto the display list and give them the following instance names: playButton , pauseButton , stopButton , backButton , and forwardButton . Google chrome download for windows 2008 64 bit.

For each of these Button instances, you'll need to assign a handler for the click event, as seen in the following snippet:

The buttonClickHandler() method uses a switch statement to determine which button instance was clicked, as seen in the following code:

Next, add a Slider instance to the display list and give it an instance name of volumeSlider . The following code sets the slider instance's liveDragging property to true and defines an event listener for the slider instance's change event:

Add a ProgressBar instance to the display list and give it an instance name of positionBar . Set its mode property to manual, as seen in the following snippet:

Finally add a Label instance to the display list and give it an instance name of positionLabel . This Label instance's value will be set by the timer instance

When Flash Player encounters metadata for each of the loaded videos, the onMetaData() callback handler is called on the NetStream object's client property. The following code initializes an Object and sets up the specified callback handler:

The metadataHandler() method copies its data to the meta property defined earlier in the code. This allows you to access the metadata for the current video anytime throughout the entire application. Next, the video object on the Stage is resized to match the dimensions returned from the metadata. Finally, the positionBar progress bar instance is moved and resized based on the size of the currently playing video. The following code contains the entire metadataHandler() method:

To dynamically load each of the videos, the application uses a NetConnection and a NetStream object. The following code creates a NetConnection object and passes null to the connect() method. By specifying null , Flash Player connects to a video on the local server instead of connecting to a server, such as a Flash Media Server.

The following code creates both the NetConnection and NetStream instances, defines an event listener for the netStatus event, and assigns the client Object to the client property:

The netStatusHandler() method is called whenever the status of the video is changed. This includes when a video starts or stops playback, is buffering or if a video stream cannot be found. Not rar archive no files to extract. The following code lists the netStatusHandler() event:

The previous code evaluates the code property of the info object and filters whether the code is 'NetStream.Play.Start', 'NetStream.Play.StreamNotFound', or 'NetStream.Play.Stop'. All other codes will be ignored. If the net stream is starting the code starts the Timer instance which updates the playhead. If the net stream cannot be found or is stopped, the Timer instance is stopped and the application attempts to play the next video in the playlist.

Every time the Timer executes, the positionBar progress bar instance updates its current position by calling the setProgress() method of the ProgressBar class and the positionLabel Label instance is updated with the time elapsed and total time of the current video.

You can control the volume for the dynamically loaded video by setting the soundTransform property on the NetStream object. The video jukebox application allows you to modify the volume level by changing the value of the volumeSlider Slider instance. The following code shows how you can change the volume level by assigning the value of the Slider component to a SoundTransform object which is set to the soundTransform property on the NetStream object: Www bluestacks com.

The rest of the application controls video playback when the video reaches the end of the video stream or the user skips to the previous or next video.

The following method retrieves the video URL from the XMLList for the currently selected index: Mac memory information.

The playVideo() method calls the play() method on the NetStream object to load the currently selected video:

The playPreviousVideo() method decrements the current video index, calls the playVideo() method to load the new video file and sets the progress bar to visible:

The final method, playNextVideo() , increments the video index and calls the playVideo() method. If the current video is the last video in the playlist, the clear() method is called on the Video object and the progress bar instance's visible property is set to false :
