The LEAD MPEG2 Program Demultiplexer is a DirectShow filter that can parse the following types of streams:
MPEG-2 Program specified in ISO/IEC 13818-1
MPEG-1 System specified in ISO/IEC 11172-1
Elementary stream data (also known as raw video or raw audio data)
The first two formats are multiplexed formats, and they can contain video, audio and private data streams. The video compression can be MPEG1 (ISO/IEC 11172-2), MPEG2 (ISO/IEC 13818-2), MPEG4 (ISO/IEC 14496-2) or H.264 (ISO/IEC 14496-10). The audio compression can be MPEG1 (ISO/IEC 11172-3), AC3, LPCM or AAC.
This filter does NOT support MPEG-2 Transport streams defined in ISO/IEC 13818-1. Those streams are supported in the LEAD MPEG2 Transport Demultiplexer.
This filter does NOT support private data. For private data support, please use the LEAD MPEG2 Transport Demultiplexer.
The demultiplexer works in pull mode, so it will connect to source filters that expose the IAsyncReader interface. IAsyncReader is a standard Microsoft interface. Please consult the Microsoft documentation for more information on IAsyncReader.
