IMultiMediaStream::GetInformation (Windows Embedded CE 6.0)

1/6/2010

This method retrieves the capabilities of a media stream that matches the specified media type.

Syntax

HRESULT GetInformation(
  DWORD* pdwFlags,
  STREAM_TYPE* pStreamType
);

pdwFlags
[out] Pointer to a value that will contain a combination of one or more of the following flags. Can be NULL.

Value	Description
MMSSF_ASYNCHRONOUS	The stream supports asynchronous sample updates. All implementations of IMultiMediaStream support the asynchronous updates; this flag confirms it.
MMSSF_HASCLOCK	The stream has a clock.
MMSSF_SUPPORTSEEK	The stream supports seeking.

MMSSF_ASYNCHRONOUS

The stream supports asynchronous sample updates.

All implementations of IMultiMediaStream support the asynchronous updates; this flag confirms it.

MMSSF_HASCLOCK

The stream has a clock.

MMSSF_SUPPORTSEEK

The stream supports seeking.

pStreamType
[out] Pointer to a STREAM_TYPE enumeration type that will contain the media type information for the derived media streams. Can be NULL.

Returns an HRESULT value.

A stream's capabilities include whether it has a clock, if it supports seeking, and whether it supports asynchronous updating.
