IMpeg2PsiParser Interface
| Microsoft DirectShow 9.0 |
IMpeg2PsiParser Interface
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.
In addition to the methods inherited from IUnknown, the IMpeg2PsiParser interface exposes the following methods.
| Method | Description |
| 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. |
| GetRecordStreamType | Retrieves the stream type for a specified elementary stream in a program. |
| GetTransportStreamId | Retrieves the transport_stream_id field from the PAT. |
