[This is preliminary documentation and subject to change.]
This component is a representation of a media in an SDP component. It exports methods to get and set media properties
| IUnknown Methods | Description |
|---|---|
| QueryInterface | Returns pointers to supported interfaces. |
| AddRef | Increments the reference count. |
| Release | Decrements the reference count. |
| IDispatch Methods | Description |
|---|---|
| GetTypeInfoCount | Retrieves the number of type information interfaces. |
| GetTypeInfo | Retrieves the type information for an object. |
| GetIDsOfNames | Maps a single member and an optional set of argument names to a corresponding set of integer DISPIDs. |
| Invoke | Provides access to properties and methods exposed by an object. |
| ITMedia Methods | Descriptions |
|---|---|
| get_MediaName | Gets the media name (BSTR). Defined media are audio, video, whiteboard, text and data. |
| put_MediaName | Sets the media name (BSTR). Defined media are audio, video, whiteboard, text and data. |
| get_StartPort | Gets the 16-bit port value (USHORT) for the first port. |
| get_NumPorts | Gets the number of ports (USHORT) needed for the session. |
| get_TransportProtocol | Gets the transport protocol (BSTR). This is specified in addition to the media format so that the same standard media format may be carried over different transport protocols even when the network protocol is the same. |
| put_TransportProtocol | Sets the transport protocol (BSTR). This is specified in addition to the media format so that the same standard media format may be carried over different transport protocols even when the network protocol is the same. |
| get_FormatCodeList | Gets the list of media payload format codes. |
| put_FormatCodeList | Sets the list of media payload format codes. |
| get_MediaTitle | Gets the media title (BSTR). This is mainly for user information or display purposes. This has to be an ASCII convertible string if the character set is ASCII. (It can be any BSTR string otherwise.) |
| put_MediaTitle | Sets the media title (BSTR). This is mainly for user information or display purposes. This has to be an ASCII convertible string if the character set is ASCII. (It can be any BSTR string otherwise.) |
| SetPortInfo | Sets the 16-bit port value (USHORT) for the first port and number of ports needed for session. |
