attachVideo (Video.attachVideo method)
deblocking (Video.deblocking property)
public deblocking : Number
Indicates the type of deblocking filter applied to decoded video as part of postprocessing. Two
deblocking filters are available: one in the Sorenson codec and one in the On2 VP6 codec.
The following values are acceptable:
■
0 (the default)—Let the video compressor apply the deblocking filter as needed.
■
1—Do not use any deblocking filter.
■
2—Use the Sorenson deblocking filter.
■
3—Use the On2 deblocking filter and no deringing filter.
■
4—Use the On2 deblocking and the fast On2 deringing filter.
■
5—Use the On2 deblocking and the better On2 deringing filter.
■
6—Same as 5.
■
7—Same as 5.
If a mode greater than 2 is selected for video when you are using the Sorenson codec, the
Sorenson decoder defaults to mode 2 internally.
Use of a deblocking filter has an effect on overall playback performance, and it is usually not
necessary for high-bandwidth video. If your system is not powerful enough, you may
experience difficulties playing back video with this filter enabled.
Availability: ActionScript 1.0; Flash Player 6
Example
The following example plays video1.flv in the
my_video
video object, and lets the user change
the deblocking filter behavior on video1.flv. Add a video object called
my_video
and a
ComboBox instance called
deblocking_cb
to your file, and then add the following
ActionScript to your FLA or AS file.
var deblocking_cb:mx.controls.ComboBox;
var my_video:Video; // my_video is a Video object on the Stage
var my_nc:NetConnection = new NetConnection();
my_nc.connect(null);
var my_ns:NetStream = new NetStream(my_nc);
my_video.attachVideo(my_ns);
my_ns.play("video1.flv");
deblocking_cb.addItem({data:0, label:'Auto'});
