Remarks

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}

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
