IMpeg2PsiParser interface
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The implementation of this interface is provided as sample code with the DirectShow SDK. It is not a supported DirectShow API.
The IMpeg2PsiParser interface retrieves Program Specific Information (PSI) from the PSI Parser filter, which is provided in the DirectShow SDK as a sample filter. An application can use this filter to map program IDs (PIDs) on the MPEG-2 Demultiplexer filter.
Members
The IMpeg2PsiParser interface inherits from the IUnknown interface. IMpeg2PsiParser also has these types of members:
Methods
The IMpeg2PsiParser interface has these methods.

|---|---|
| FindRecordProgramMapPid | Finds the Program Map Table (PMT) PID for a program, given the program number. |
| GetCountOfElementaryStreams | Retrieves the number of elementary streams in a specified program. |
| GetCountOfPrograms | Retrieves the number of programs in the transport stream. |
| GetPatVersionNumber | Retrieves the version_number field from the Program Association Table (PAT). |
| GetPmtVersionNumber | Retrieves the version_number field from a specified PMT. |
| GetRecordElementaryPid | Retrieves the PID assignment for a specified elementary stream in a program. |
| GetRecordProgramMapPid | Retrieves the PID assignment for a specified PMT. |
| GetRecordProgramNumber | Retrieves the program number for a specified program. |
