virtual property int SourceProgramCount { 
   int get();

Property Value

A value representing the number of programs.

Remarks

Currently, only MPEG2 Transport files can have more than one program. All the other file formats have only one program, so for them SourceProgramCount will return 1. If you do have more than one program, call CurrentSourceProgram to get or set the current program.

Once you set the current program, you can use GetSourceStreamCount to find out how many elementary streams are present in the current program.

Use SetSelectedSourceStream to select which streams you wish to play.
