IWMStreamConfig interface
The IWMStreamConfig interface is the primary interface of a stream configuration object. It provides methods to configure basic properties for streams to be used in a profile.
Every profile contains one or more stream configuration objects. You can get the IWMStreamConfig interface of a stream configuration object by calling the IWMProfile::GetStream method or the IWMProfile::GetStreamByNumber method. The difference between these two methods is that GetStream retrieves the stream using an index ranging from zero to one less than the total stream count, and GetStreamByNumber retrieves the stream using the assigned stream number. You can also retrieve a stream configuration object using the IWMProfile::CreateNewStream method. All of the methods that create stream configuration objects set a pointer to this interface.
Methods
The IWMStreamConfig interface has these methods.
| Method | Description |
|---|---|
| IWMStreamConfig::GetBitrate | The GetBitrate method retrieves the bit rate for the stream. |
| IWMStreamConfig::GetBufferWindow | The GetBufferWindow method retrieves the maximum latency between when a stream is received and when it begins to be displayed. |
| IWMStreamConfig::GetConnectionName | The GetConnectionName method retrieves the input name given to the stream. |
| IWMStreamConfig::GetStreamName | The GetStreamName method retrieves the stream name. |
| IWMStreamConfig::GetStreamNumber | The GetStreamNumber method retrieves the stream number. |
| IWMStreamConfig::GetStreamType | The GetStreamType method retrieves the major type of the stream (audio, video, or script). |
| IWMStreamConfig::SetBitrate | The SetBitrate method specifies the bit rate for the stream. |
| IWMStreamConfig::SetBufferWindow | The SetBufferWindow method specifies the maximum latency between when a stream is received and when it begins to be displayed. |
| IWMStreamConfig::SetConnectionName | The SetConnectionName method specifies a name for an input. If the profile you are creating contains multiple bit rate mutual exclusion, each of the mutually exclusive streams must have the same connection name. |
| IWMStreamConfig::SetStreamName | The SetStreamName method assigns a name to the stream represented by the stream configuration object. |
| IWMStreamConfig::SetStreamNumber | The SetStreamNumber method specifies the stream number. |
