| IAVIStream::Delete The Delete method deletes data from a stream. |
| IAVIStream::FindSample The FindSample method obtains the position in a stream of a key frame or a nonempty frame. Called when an application uses the AVIStreamFindSample function. |
| IAVIStream::Info The Info method fills and returns an AVISTREAMINFO structure with information about a stream. Called when an application uses the AVIStreamInfo function. |
| IAVIStream::Read The Read method reads data from a stream and copies it to an application-defined buffer. If no buffer is supplied, it determines the buffer size needed to retrieve the next buffer of data. Called when an application uses the AVIStreamRead function. |
| IAVIStream::ReadData The ReadData method reads data headers of a stream. Called when an application uses the AVIStreamReadData function. |
| IAVIStream::ReadFormat The ReadFormat method obtains format information from a stream. |
| IAVIStream::SetFormat The SetFormat method sets format information in a stream. Called when an application uses the AVIStreamSetFormat function. |
