public:
void SetSelectedStream( 
   StreamFormatType streamType,
   int val
) 

Parameters

streamType

A StreamFormatType enumeration value specifying the desired stream type Only video and audio streams are currently supported, so this parameter should be StreamFormatType.Audio or StreamFormatType.Video.

val

The 0-based index of the stream to select

The index of the program is 0-based, so it should be between 0 and StreamCount(streamType) - 1, where StreamCount(streamType) is the number of streams of type streamType in the current program. You can get the number of streams of type streamType by calling GetStreamCount(streamType).

The streams of a particular type are mutually exclusive, so selecting one stream will automatically unselect the previously selected stream of the same type.

You can get the index of the current stream by calling GetSelectedStream.

If you change the current program by calling CurrentProgram, the stream selection might change because the number of streams of type streamType might change.
