IMFTransform::GetOutputStreamInfo method (mftransform.h)
Gets the buffer requirements and other information for an output stream on this Media Foundation transform (MFT).
HRESULT GetOutputStreamInfo( DWORD dwOutputStreamID, MFT_OUTPUT_STREAM_INFO *pStreamInfo );
Output stream identifier. To get the list of stream identifiers, call IMFTransform::GetStreamIDs.
Pointer to an MFT_OUTPUT_STREAM_INFO structure. The method fills the structure with information about the output stream.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
||The method succeeded.|
||Invalid stream number.|
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.
