Media
components (Flash Professional only)
The streaming media components make it easy to incorporate streaming media into Flash
presentations. These components let you present your media in a variety of ways.
You can use the following three media components:
•
The MediaDisplay component lets media stream into your Flash content without a supporting
user interface. You can use this component with video and audio data. When you use this
component by itself, the user has no control over the media.
•
The MediaController component provides standard user interface controls (play, pause, and so
on) for media playback. Media is never loaded into or played by this component; it is used only
for controlling playback in a MediaPlayback or MediaDisplay instance. The MediaController
component features a "drawer," which displays the contents of the playback controls when the
mouse is positioned over the component.
•
The MediaPlayback component is a combination of the MediaDisplay and MediaController
components; it provides methods to stream your media content.
Bear in mind these points about media components:
•
The media components require Flash Player 6 or later. In Flash Player 6, media components
support FLV files only through Flash Remoting, not through HTTP.
•
The media components do not support scan forward and scan backward functionality.
However, you can effect this functionality by moving the playback slider.
•
Only component size and controller policy are reflected in the live preview.
•
The media components do not support accessibility.
Interacting with media components (Flash Professional only)
The streaming MediaPlayback and MediaController components respond to mouse and
keyboard activity; the MediaDisplay component does not. The following table summarizes the
actions for the MediaPlayback and MediaController components upon receiving focus:
