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.
Inheritance
The ITSubStreamControl interface inherits from the IDispatch interface. ITSubStreamControl also has these types of members:
Methods
The ITSubStreamControl interface has these methods.
| ITSubStreamControl::CreateSubStream The CreateSubStream method creates a substream. |
| ITSubStreamControl::EnumerateSubStreams 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. |
| ITSubStreamControl::get_SubStreams 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. |
| ITSubStreamControl::RemoveSubStream The RemoveSubStream method removes a substream. |
