IAMStreamSelect Interface

The IAMStreamSelect interface controls which logical streams are played and retrieves information about them.

Implement this interface on your filter when you want to enable selection of logical streams and provide information about them. An example of logical stream selection is selection from a set of audio streams that encode different national languages. Perhaps you could choose English from among a set of audio streams that include English, German, and French. The MPEG splitter implements this interface.

Use this interface when you want to select between available streams; for example, when you want to select the streams for a particular locale.
