Property Value

Constants.Filter_MPEG2_Splitter Constants.Filter_MPEG2_Demux Constants.Filter_MPEG2_Program_Demux Constants.Filter_MPEG2_Transport_Demux

True	Microsoft MPEG-2 Splitter.
False	Microsoft MPEG-2 Demultiplexer.
False	LEAD MPEG-2 Program Demultiplexer.
False	LEAD MPEG-2 Transport Demultiplexer.

The MPEG2 Splitter is a demultiplexer that takes an MPEG2 stream as input and breaks out the available streams as output pins. Possible outputs are Video, Audio, CC, etc. A display name uniquely identifies the splitter (or any filter). Different splitters can offer additional interfaces and functionality based on their design. Display names for software splitters have the following format: @device:sw:GUID\\GUID. For example, the display name for Microsoft's 'MPEG-2 Splitter is: @device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\\{3AE86B20-7BE8-11D1-ABE6-00A0C905F375}
