IMVSCSetSourceFilter

The IMVSCSetSourceFilter Interface from the MontiVision Smart Control provides methods to change the video source within a filter graph configuration. It reconnects the filter graph to work with the new video source. For this to work, the filter graph must be in the state:  STATE_STOP to change the video source.

Methods:

Typelib: MV Smart Control

Method IMVSCSetSourceFilter::SetSourceFilter

Declaration: Sub SetSourceFilter(Filter As String, NewFilterDisplayName As String)

Replaces an existing source filter with a new source. The new source was created with the display name.

Parameter:

	Filter	Video source filter label within the filter graph configuration.
	NewFilterDisplayName	Display name from the new video source filter.

Use the MV VideoSourceComboBox to change the video source  within a filter graph configuration. It provides the display name from the current selected video device. The display name is a complex string that contains all information to create a video source filter that wraps a video device.
