public virtual int ProgramCount {get;}

'Declaration

Public Overridable ReadOnly Property ProgramCount As Integer

'Usage

Dim instance As PlayCtrl
Dim value As Integer
 
value = instance.ProgramCount

public:
virtual property int ProgramCount {
   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 ProgramCount will return 1.

If you do have more than one program, call CurrentProgram to get or set the current program.

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

Use SetSelectedStream to select which streams you wish to play.
