IDVDProgramChain
This interface provides information about the program chain that is currently playing.
The following table lists the methods for IDVDProgramChain in the order the compiler calls them.
| Programming element | Description |
|---|---|
| GetDomain | Returns a pointer to the IDVDDomain interface for the parent domain of the current program chain. |
| GetContents | Returns the program chain contents (PGC_CNT) for the current program chain (PGC). |
| GetPlaybackTime | Returns the program chain playback time (PGC_PB_TM) for the current program chain (PGC). |
| GetUserOperationControlMask | Returns the PGC user operation control (PGC_UOP_CTL) for the current program chain (PGC). |
| GetAudioStreamSelector | Returns the PGC audio stream control (PGC_AST_CTL) information for a specified audio stream in the current program chain (PGC). |
| GetSubpictureStreamSelector | Returns the PGC subpicture stream control (PGC_SPST_CTL) information for a specified audio stream in the current program chain (PGC). |
| GetLink | Returns a PGC number (PGCN) from the PGC navigation control (PGC_NV_CTL) based on a specified navigation direction. |
| GetPlaybackMode | Returns the playback mode, repeat count, and still time value from the PGC navigation control (PGC_NV_CTL) for the current program chain (PGC). |
| GetSubpicturePalette | Returns a buffer containing all 16 PGC subpicture palettes (PGC_SP_PLT) for the current program chain (PGC). |
| GetNavCommandsCount | Returns the number of program command of a specified type from the PGC command table information (PGC_CMDTI) for the current program chain (PGC). |
| GetNavCommand | Returns the navigation command of a specified type from the PGC command table (PGC_CMDT) for the current program chain (PGC). |
| GetProgramEntryCell | Returns the entry cell number (EN_CN) for a specified program number for the current program chain (PGC). |
| GetCellPlaybackInfo | Returns cell playback information (C_PBI) for a specified cell in the current program chain (PGC). |
| GetCellPosition | Returns cell position information (C_POSI) for a specified cell in the current program chain (PGC). |
| GetPGCN | Returns the program chain number (PGCN) for the current program chain (PGC) |
The IDVDProgramChain interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
Remarks
You can obtain a pointer to an IDVDProgramChain interface in the following ways:
- By calling the IUnknown::QueryInterface method of a DVDData object and specifying the IID_IDVDProgramChain reference identifier.
- By calling the IDVDDomain::GetPGC method.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Dvdata.h, Dvdata.idl.
