IMFTransform interface (Windows)

IMFTransform interface

Applies to: desktop apps | Metro style apps

Implemented by all Media Foundation Transforms (MFTs).

When to implement

Implement this interface if you are writing a custom MFT.

Members

The IMFTransform interface inherits from the IUnknown interface. IMFTransform also has these types of members:

Methods

Methods

The IMFTransform interface has these methods.

Method	Description
AddInputStreams	Adds one or more new input streams to this MFT.
DeleteInputStream	Removes an input stream from this MFT.
GetAttributes	Retrieves the attribute store for this MFT.
GetInputAvailableType	Retrieves a possible media type for an input stream on this MFT.
GetInputCurrentType	Retrieves the current media type for an input stream on this MFT.
GetInputStatus	Queries whether an input stream on this MFT can accept more data.
GetInputStreamAttributes	Retrieves the attribute store for an input stream on this MFT.
GetInputStreamInfo	Retrieves the buffer requirements and other information for an input stream.
GetOutputAvailableType	Retrieves an available media type for an output stream on this MFT.
GetOutputCurrentType	Retrieves the current media type for an output stream on this MFT.
GetOutputStatus	Queries whether the transform is ready to produce output data.
GetOutputStreamAttributes	Retrieves the attribute store for an output stream on this MFT.
GetOutputStreamInfo	Retrieves the buffer requirements and other information for an output stream on this MFT.
GetStreamCount	Retrieves the current number of input and output streams on this MFT.
GetStreamIDs	Retrieves the stream identifiers for the input and output streams on this MFT.
GetStreamLimits	Retrieves the minimum and maximum number of input and output streams.
ProcessEvent	Sends an event to an input stream on this MFT.
ProcessInput	Delivers data to an input stream on this MFT.
ProcessMessage	Sends a message to the MFT.
ProcessOutput	Generates output from the current input data.
SetInputType	Sets, tests, or clears the media type for an input stream on this MFT.
SetOutputBounds	Sets the range of timestamps the client needs for output.
SetOutputType	Sets, tests, or clears the media type for an output stream on this MFT.
