The LEAD MPEG-4 Encoder is a MediaFoundation® transform for compressing video data using the MPEG-4 standard (ISO/IEC 14496-2). MPEG-4 is suitable for a wide range of bandwidths from low bandwidth to broadband. In addition to MP4 files, MPEG4 compressed video data can be stored inside AVI or OGG files with the option of saving the file with or without the audio data. The LEAD MPEG-4 Video Encoder is easily configurable through a programming interface and provides the ability to deliver a video that is most suitable for the intended application.
The LEAD MPEG-4 Video Encoder implements the standard IMFTransform interface and can be configured by setting attributes on its output media type.
This transform supports the standard ICodecAPI interface which can be used to configure the encoder, Please see the Microsoft documentation for this interface for more information.
