IMFTransform::GetOutputStreamInfo method

Gets the buffer requirements and other information for an output stream on this Media Foundation transform (MFT).

Syntax

HRESULT GetOutputStreamInfo(
  DWORD                  dwOutputStreamID,
  MFT_OUTPUT_STREAM_INFO *pStreamInfo
);

Parameters

dwOutputStreamID

Output stream identifier. To get the list of stream identifiers, call IMFTransform::GetStreamIDs.

pStreamInfo

Pointer to an MFT_OUTPUT_STREAM_INFO structure. The method fills the structure with information about the output stream.

Return Value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
The method succeeded.
MF_E_INVALIDSTREAMNUMBER
Invalid stream number.

Remarks

It is valid to call this method before setting the media types. Note that the results of this call can change dynamically after the media type changes and after ProcessOutput is called, so you may need to call this method again after either of these occur.

If MFT_UNIQUE_METHOD_NAMES is defined before including mftransform.h, this method is renamed MFTGetOutputStreamInfo. See Creating Hybrid DMO/MFT Objects.
