The IMSVidClosedCaptioning interface enables or disables closed captions. The MSVidClosedCaptioning feature exposes this interface.
To obtain this interface, enumerate the collection of available features on the Video Control. To use closed captioning, activate the closed captioning feature before you build the graph. Once the feature is active, you can enable or disable the closed captioning display by calling the IMSVidClosedCaptioning::put_Enable method.
In addition to the methods inherited from IMSVidFeature, the IMSVidClosedCaptioning interface exposes the following methods.
|get_Enable||Queries whether closed captioning is enabled.|
|put_Enable||Enables or disables closed captioning.|
