MPEG-2 Demultiplexer
This filter demultiplexes MPEG-2 transport and program streams that are delivered in push-mode. Starting in Windows XP, this filter also supports program streams in pull mode (file playback). On earlier platforms, use the MPEG-2 Splitter filter for program streams in pull mode. This filter can be used in any type of filter graph, including a BDA digital TV filter graph.
Note The MPEG-2 Demultiplexer does not support frame-accurate seeking.

Audio and video elementary streams must have a major type of MEDIATYPE_Audio or MEDIATYPE_Video. For more information, see MPEG-2 Demultiplexer Media Types. |

Remarks
To output audio and video elementary streams, the demux must receive the PCR and SCR streams. On the input side, this means a transport stream must contain the PAT and PMT tables that define the PID for the PCR stream; and program streams must contain at least one pack header.
