Public ReadOnly Property AudioStreamCount As Integer
public int AudioStreamCount { get; }

Property Value

Type: System.Int32
The number of audio streams that exist in the source media file. The default value is 0.

Remarks

Dependency property identifier field: AudioStreamCountProperty

The AudioStreamCount property value is valid only after the MediaOpened event has been raised.

AudioStreamIndex and AudioStreamCount both specifically refer to a collection of only audio streams. This collection is composed locally at run time. If you were to examine the actual media, the audio streams might be interleaved with non-audio stream types, but these other streams will not be part of the collection.
