Errors

Errors may not be returned from this function (see SetError()).

Remarks

RedoFrame() is used whenever configuration parameters are changed on the filter and allows the preview to be updated with the new result. Unlike RedoSystem(), RedoFrame() only regenerates frames and should be preferred whenever possible for speed.

V14+ only: RedoFrame() also invalidates all frame caches for the filter being configured and all downstream filters. This prevents any cached frames generated with old filter settings from being displayed.
