VideoElement is a media element specifically created for video playback. It supports streaming and progressive formats, as well as HTTP streaming and MBR streaming (for both RTMP and HTTP).

VideoElement is a more full-featured alternative to LightweightVideoElement. Whereas LightweightVideoElement supports only a subset of video delivery modes (specifically progressive and simple RTMP streaming), VideoElement supports all video delivery modes.

The VideoElement uses a NetLoader class to load and unload its media. Developers requiring custom loading logic for video can pass their own loaders to the LightweightVideoElement constructor. These loaders should subclass NetLoader.

The basic steps for creating and using a LightweightVideoElement are:

Create a new URLResource pointing to the URL of the video stream or file containing the video to be loaded.
Create a new NetLoader.
Create the new VideoElement, passing the NetLoader and URLResource as parameters.
Create a new MediaPlayer.
Assign the VideoElement to the MediaPlayer's media property.
Control the media using the MediaPlayer's methods, properties, and events.
When done with the VideoElement, set the MediaPlayer's media property to null. This will unload the VideoElement.

The VideoElement supports Flash Media Token Authentication, for passing authentication tokens through the NetConnection.

The VideoElement has support for the Flash Player's DRM implementation. Note that the startDate, endDate, and period properties of the DRMTrait on this element correspond to the voucher validity before playback starts. Once playback begins, these properties correspond to the playback time window (as found on flash.net.drm.DRMVoucher).

	`resource:MediaResourceBase` (default = `null`) — URLResource that points to the video source that the VideoElement will use. For dynamic streaming content, use a DynamicStreamingResource.

	`loader:NetLoader` (default = `null`) — NetLoader used to load the video. If null, the appropriate NetLoader will be created based on the resource type.
