_MFT_PROCESS_OUTPUT_STATUS enumeration (mftransform.h)

  • Article

Indicates the status of a call to IMFTransform::ProcessOutput.

Syntax

typedef enum _MFT_PROCESS_OUTPUT_STATUS {
  MFT_PROCESS_OUTPUT_STATUS_NEW_STREAMS = 0x100
} ;

Constants

 
MFT_PROCESS_OUTPUT_STATUS_NEW_STREAMS
Value: 0x100
The Media Foundation transform (MFT) has created one or more new output streams.

Remarks

If the MFT sets this flag, the ProcessOutput method returns MF_E_TRANSFORM_STREAM_CHANGE and no output data is produced. The client should respond as follows:

  1. Call IMFTransform::GetStreamCount to get the new number of streams.
  2. Call IMFTransform::GetStreamIDs to get the new stream identifiers.
  3. Call IMFTransform::GetOutputAvailableType and IMFTransform::SetOutputType to set the media types on the new streams.
Until these steps are completed, all further calls to ProcessOutput return MF_E_TRANSFORM_STREAM_CHANGE.

Requirements

Requirement Value
Minimum supported client Windows Vista [desktop apps | UWP apps]
