ref_iface_IVDXFilterPreview_RedoFrame
VirtualDub Plugin SDK 1.2
IVDXFilterPreview interface
Refilters and redisplays the current frame.
void RedoFrame();
This method is not thread-safe.
Errors may not be returned from this function (see SetError()).
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.
