Parameters

lSourceIndex (Optional)
Type: SystemInt32
Index of the source of interest, or -1 for all sources.

Property Value

Type: Object
Remarks
Each source has a starting frame index for aligning its mapped frame sequence with the mapped frame sequences of the other sources. This is given as the starting mapped destination frame index for the corresponding Sources element for association with to the other sources' frames. The shift must be less than the mapped destination FrameCount for each source, so you should assign to the SourceFrameMapping property before this one. Negative values are allowed and effectively act to lenghten the mapped destination FrameCount for a source by prepending missing frames; that is, the SourceStartingFrame can be used to offset a source's frame sequence by either shifting it backwards (positive SourceStartingFrame) or forwards (positive SourceStartingFrame) relative to other sources. By default zero is assumed for all sources. This property is exposed and assigned to as a scalar Long (type VT_I4) or an array thereof.
