Comments
This function allows the user to store a complete media file in global memory and use it as the source for the conversion process. The user is responsible for allocating, initializing, and freeing the global memory. However, the user should not free the global memory handle while the convert object holds a reference to it. The ResetSource function should be called to stop the convert object from accessing the global memory. The SourceType will be set to ltmmConvert_Source_HGlobal.
