IDVDDataSearchInfo (Windows CE 5.0)
This interface provides access to the data search information (DSI) for a video object unit (VOBU).
The following table lists the methods for IDVDDataSearchInfo in the order the compiler calls them.
| Method | Description |
|---|---|
| GetControlInfo | Returns the IDVDStreamControlInfo interface. |
| GetSCRBase | Returns the system clock reference base (SCR_base) of the current navigation pack (NV_PCK). |
| GetUnitEndAddress | Returns the video object unit end address (VOBU_EA) from the data search information general information (DSI_GI). |
| GetRefPictureAddress | Returns the relative address of the first, second, or third reference picture in the video object unit (VOBU). |
| GetVOB_ID | Returns the video object unit's video object identification number (VOBU_VOB_IDN). |
| GetC_IDN | Returns the video object unit's cell identification number (VOBU_C_IDN). |
| GetSeamlessCategory | Returns the video object unit's seamless playback category (VOBU_SML_CAT). |
| GetInterleavedUnitEndAddress | Returns the interleaved unit's end address (ILVU_EA). |
| GetNextInterleavedUnit | Returns the next interleaved unit's start address (NXT_ILVU_SA) and the next interleaved unit's size (NXT_ILVU_SZ). |
| GetAudioGapInfo | Returns information about audio discontinuities in the current video object (VOB). |
| GetSeamlessAngleChangeAddress | Returns a specified seamless angle change's destination address (SML_AGL_Cn_DSTA) and size. |
| GetUnitStepAddress | Returns the address of a video object unit (VOBU) that is a specified distance forward or behind in the presentation. |
| GetSyncAudioAddress | Returns the target audio pack address (A_SYNCA) for a specified audio stream. |
| GetSyncSPAddress | Returns the video object unit (VOBU) start address for the target subpicture (SP_SYNCA) of a specified subpicture stream. |
The IDVDDataSearchInfo 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 IDVDDataSearchInfo interface in the following ways:
- By calling the IUnknown::QueryInterface method of a DVDData object and specifying the IID_IDVDDataSearchInfo interface identifier, see DVD-Video API Interface Identifiers.
- By calling the IDVDStreamControlInfo::GetDataSearchInfo method.
Requirements
