public int OutputStreams {get;}

'Declaration

Public ReadOnly Property OutputStreams As Integer

'Usage

Dim instance As MediaInfo
Dim value As Integer
 
value = instance.OutputStreams

public:
property int OutputStreams {
   int get();
}

Property Value

A value representing the number of output streams available in the current program.

The current source media file is the file that the MediaInfo object gets information for. To set the current source media file, set the SourceFile property. The source file has one or more programs and each program has one or more output streams. The value of this property might change if you change the value of the current program using the CurrentProgram property. The value of this property can be used to iterate through all streams, acquiring information on each. To set the current stream, set the CurrentStream property. Once the current stream has been set, other MediaInfo properties are updated with information about the current stream.
