BufferingBar component

The buffering bar component is simple: It consists of an animation that is made visible when the component enters the buffering state, and it does not require any special ActionScript to configure it. By default, it is a striped bar moved from left to right with a rectangular mask on it to give it a "barber pole" effect, but there is nothing special about this configuration.

Although the buffering bars in the skin SWF files use 9-slice scaling because they need to be scaled at runtime, the BufferingBar FLV Custom UI Component does not and cannot use 9-slice scaling because it has nested movie clips. If you want to make the BufferingBar wider or taller, you might want to change its contents rather than scale it.
