Indicates the type of filter applied to decoded video as part of post-processing. The default value is 0, which lets the video compressor apply a deblocking filter as needed.

Compression of video can result in undesired artifacts. You can use the deblocking property to set filters that reduce blocking and, for video compressed using the On2 codec, ringing.

Blocking refers to visible imperfections between the boundaries of the blocks that compose each video frame. Ringing refers to distorted edges around elements within a video image.

Two deblocking filters are available: one in the Sorenson codec and one in the On2 VP6 codec. In addition, a deringing filter is available when you use the On2 VP6 codec. To set a filter, use one of the following values:

• 0—Lets the video compressor apply the deblocking filter as needed.
• 1—Does not use a deblocking filter.
• 2—Uses the Sorenson deblocking filter.
• 3—For On2 video only, uses the On2 deblocking filter but no deringing filter.
• 4—For On2 video only, uses the On2 deblocking and deringing filter.
• 5—For On2 video only, uses the On2 deblocking and a higher-performance On2 deringing filter.

If a value greater than 2 is selected for video when you are using the Sorenson codec, the Sorenson decoder defaults to 2.

Using a deblocking filter has an effect on overall playback performance, and it is usually not necessary for high-bandwidth video. If a user's system is not powerful enough, the user may experience difficulties playing back video with a deblocking filter enabled.

Specifies whether the video should be smoothed (interpolated) when it is scaled. For smoothing to work, the player must be in high-quality mode. The default value is false (no smoothing).

For video playback using Flash Player 9.0.115.0 and later versions, set this property to true to take advantage of mipmapping image optimization.

An integer specifying the height of the video stream, in pixels. For live streams, this value is the same as the Camera.height property of the Camera object that is capturing the video stream. For FLV files, this value is the height of the file that was exported as FLV.

You may want to use this property, for example, to ensure that the user is seeing the video at the same size at which it was captured, regardless of the actual size of the Video object on the Stage.

An integer specifying the width of the video stream, in pixels. For live streams, this value is the same as the Camera.width property of the Camera object that is capturing the video stream. For FLV files, this value is the width of the file that was exported as an FLV file.

You may want to use this property, for example, to ensure that the user is seeing the video at the same size at which it was captured, regardless of the actual size of the Video object on the Stage.

Creates a new Video instance. If no values for the width and height parameters are supplied, the default values are used. You can also set the width and height properties of the Video object after the initial construction, using Video.width and Video.height. When a new Video object is created, values of zero for width or height are not allowed; if you pass zero, the defaults will be applied.

After creating the Video, call the DisplayObjectContainer.addChild() or DisplayObjectContainer.addChildAt() method to add the Video object to a parent DisplayObjectContainer object.

Specifies a video stream from a camera to be displayed within the boundaries of the Video object in the application.

Use this method to attach live video from a user's computer to the Video object. You can play the live video locally on the same computer on which it is being captured, or you can send it to Flash Media Server and use the server to stream it to other users.

Parameters

See also

Specifies a video stream to be displayed within the boundaries of the Video object in the application. The video stream is either an FLV file played with NetStream.play(), a Camera object, or null. If you use an FLV file, it can be stored on the local file system or on Flash Media Server. If the value of the netStream argument is null, the video is no longer played in the Video object.

You do not need to use this method if the FLV file contains only audio; the audio portion of FLV files is played automatically when you call NetStream.play(). To control the audio associated with an FLV file, use the soundTransform property of the NetStream object that plays the FLV file.

Parameters

See also

Clears the image currently displayed in the Video object (not the video stream). This method is useful for handling the current image. For example, you can clear the last image or display standby information without hiding the Video object.

In this example, the code that creates the Video and NetStream objects and calls Video.attachNetStream() and NetStream.play() is placed in a handler function. The handler is called only if the attempt to connect to the NetConnection object is successful, which is when the netStatus event returns an info object with a code property that indicates success. It is recommended that you wait for a successful connection before calling NetStream.play().
