IWMReaderTimecode interface

The IWMReaderTimecode interface provides access to information about SMPTE (Society of Motion Picture and Television Engineers) time code ranges. A range of SMPTE time code is a series of samples with time codes that are contiguous and in increasing order. An individual video stream can contain more than one range.

An IWMReaderTimecode interface exists for every reader object. You can obtain a pointer to an instance of this interface by calling the QueryInterface method of any other interface of the reader object.


The IWMReaderTimecode interface inherits from the IUnknown interface. IWMReaderTimecode also has these types of members:


The IWMReaderTimecode interface has these methods.


Retrieves the starting and ending time codes for a specified SMPTE time code range.


Retrieves the total number of SMPTE time code ranges for a specified stream.


For information about which interfaces can be obtained by using the QueryInterface method of this interface, see Reader Object.
