Using the Encoder MFT
An encoder converts uncompressed audio or video into compressed packets in the format specified by the application. In Media Foundation, an encoder is implemented as a Media Foundation transform (MFT) that exposes the IMFTransform interface. An MFT is a pipeline component that is responsible for transforming media data that flows through the source to the sink. An encoder has one input stream and one output stream. The encoder receives input data and produces encoded data according to the configuration and format set by the application prior to the encoding session. The format of the output stream is described by a media type.
