Video class
Flash Lite 2.x lets you work with device-specific video formats, and supports the following types of video playback:
- Video embedded in a SWF file
- Video available as a separate file on the device
- Video streamed over the network (in real time)
Flash Lite 2.x supports device video. Device video is stored in the published SWF file in the device's native video format. To play the device video, Flash Lite passes the video data to the device, which then decodes and plays the video.

NOTE |
|
Flash Lite 2.x ActionScript does not support the NetConnection or NetStream classes. |
Flash Lite 3.0 adds support for Flash Video (FLV) using versions of the On2 and Sorenson codecs optimized for mobile devices. FLV video is rendered directly in the Flash Lite player rather than by the device, so you no longer need to be concerned about whether your target devices support a particular video format. The ActionScript NetConnection and NetStream classes, which were not previously available in Flash Lite, let you control the playback of FLV video from a local drive or HTTP address. These classes are described in Chapter 2, "ActionScript Classes," in Flash Lite 2.x and 3.0 ActionScript Language Reference. Streaming video data over an RTMP connection to a Flash Media Server is also supported in Flash Lite 3.0 (but RTMPT and RTMPS connections are not). The Camera class and recording video are not supported for Flash Video.
Flash Lite 3.0 also includes a new property in the Video class, attachVideo, that specifies a video stream to be displayed within the boundaries of the Video object on the Stage. You use the methods of the NetStream class rather than those of the Video class to control playback of FLV (non-device) video. For example, to pause device video, you use the Video.pause method, but to pause FLV video, you use NetStream.pause.
