M4a codec windows media player 95/29/2023 ![]() ![]() This section contains the following topics. The format of the output stream is described by a media type. The encoder receives input data and produces encoded data according to the configuration and format set by the application prior to the encoding session. ![]() An encoder has one input stream and one output stream. If the source is a compressed type, then the pipeline adds the required decoders to convert the source into an uncompressed type. If you are using pipeline layer components for ASF encoding, the encoder MFT is inserted into the pipeline as a transform node because it is responsible for transforming media data that flows through the source to the sink. These encoders are implemented as Media Foundation transform (MFT) and Media Foundation provides access to the application through the IMFTransform interface of the encoder. SubType: MFVideoFormat_WVC1, MFVideoFormat_WMV3, MFVideoFormat_WMV2, MFVideoFormat_WMV1 SubType: MFAudioFormat_WMAudioV9, MFAudioFormat_WMAudioV8, MFAudioFormat_WMAudio_Lossless, MFAudioFormat_WMASPDIF The encoder's output type is represented by a media type's major and the sub type GUID. For converting media files into ASF format, you can use the Windows Media audio and video codecs.Īn encoder is identified by the GUID that represents the category: audio or video. An encoder converts uncompressed audio or video into compressed packets in the format specified by the application.
