ITSubStreamControl interface (tapi3if.h)
The ITSubStreamControl interface exposes methods that allow an application to enumerate, create, or remove substreams. Many MSPs do not support this interface.
A pointer to this interface can be obtained by calling QueryInterface on the stream object.
The ITSubStreamControl interface inherits from the IDispatch interface. ITSubStreamControl also has these types of members:
The ITSubStreamControl interface has these methods.
The CreateSubStream method creates a substream.
The EnumerateSubStreams method enumerates currently available media substreams. Provided for C and C++ applications. Automation client applications such as Visual Basic must use the get_SubStreams method.
The get_SubStreams method creates a collection of substreams currently available. Provided for Automation client applications, such as those written in Visual Basic. C and C++ applications must use the EnumerateSubStreams method.
The RemoveSubStream method removes a substream.
