Video -- Version 8

The Video class enables you to display live streaming video on the Stage without embedding it in your SWF file. You capture the video by using Camera.get(). In files published for Flash Player 7 and later, you can also use the Video class to play back Flash Video (FLV) files over HTTP or from the local file system. For more information, see the NetConnection class and NetStream class entries.

Flash Player 7 supports Flash video (FLV) encoded with the Sorenson Spark video codec. Flash Player 8 supports Flash video (FLV) encoded with either the Sorenson or the On2 VP6 codec and also supports an alpha channel. The On2 VP6 video codec uses less bandwidth than older technologies, and offers additional deblocking and deringing filters.

If your Flash content dynamically loads Flash video (using either progressive download or Flash Communication Server), you can use On2 VP6 video without having to republish your SWF for Flash Player 8, as long as users view your content through Flash Player 8. By streaming or downloading On2 VP6 video into Flash SWF version 6 or 7, and playing the content using Flash Player 8, you avoid having to recreate your SWF files for use with Flash Player 8.

* If your Flash content dynamically loads Flash video (FLV), you can use On2 VP6 video without having to republish your SWF for Flash Player 8, as long as users use Flash Player 8 to view your content. Only Flash Player 8 supports both publish and playback of On2 VP6 video.

Codec	Content (SWF)Version(publish version)	Flash PlayerVersion(version required for playback)
Sorenson Spark	6	6, 7, 8
7	7, 8
On2 VP6	6	8*
7	8
8	8

A Video object can be used like a movie clip. As with other objects you place on the Stage, you can control various properties of Video objects. For example, you can move the Video object around on the Stage by using its _x and _y properties, you can change its size using its _height and _width properties, and so on.

To display the video stream, first place a Video object on the Stage. Then use Video.attachVideo() to attach the video stream to the Video object.

Availability: ActionScript 1.0; Flash Player 6 - The ability to play Flash Video (FLV) files was added in Flash Player 7. The ability to use the On2 VP6 codec and to use an alpha channel was added in Flash Player 8.

How to add video with alpha.

Hello snah, there is an example of alpha video used with the FLV Playback component at http://www.macromedia.com/support/documentation/en/flash/fl8/samples.html.

I imported and embedded a video on my stage and would really like to be able to mute/adjust the volume.

How can I grab one frame from camera and use it as picture? I t will better if I can work with this image with FileReference. :)

it seems that it is not possible to dynamically create a Video object for playing back video using this object. The Video object must be dragged to the stage and then referenced via ActionScript. I've tried it and wasn't able to get it to work and found this reference confirming my suspicions:

I want my video._width and video._height to adjust to any loaded video. To do this I retrieve the video.width and video.height.
The problem is that when I load a different video it maintains the previous video's width and height (stream not object).
Is there a way of reseting the stream's width and height or a onLoadStart method?
