ref_iface_IVDXFilterPreview_isPreviewEnabled
VirtualDub Plugin SDK 1.2
IVDXFilterPreview interface
Queries whether previewing is enabled.
bool isPreviewEnabled();
This method is not thread-safe.
Errors may not be returned from this function (see SetError()).
Returns true if a video source is available and previewing is enabled, false otherwise.
Note that this function queries whether preview is possible, not whether the preview window is currently displayed.
Filters can be configured when no video source is present. In that case, no live preview is possible.
