IMpeg2Stream::Initialize method (mpeg2data.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The Initialize method initializes the MPEG2Stream object. This method should be called once, immediately after creating the object. The IMpeg2Data::GetStreamOfSections method calls this method internally, so typically an application will not call it.
Syntax
HRESULT Initialize(
[in] MPEG_REQUEST_TYPE requestType,
[in] IMpeg2Data *pMpeg2Data,
[in] PMPEG_CONTEXT pContext,
[in] PID pid,
[in] TID tid,
[in] PMPEG2_FILTER pFilter,
[in] HANDLE hDataReadyEvent
);
Parameters
[in] requestType
Specifies the request type, as an MPEG_REQUEST_TYPE value.
[in] pMpeg2Data
Pointer to the IMpeg2Data interface of the MPEG-2 Sections and Tables filter.
[in] pContext
Pointer to an MPEG_CONTEXT structure. This structure indicates the MPEG-2 source.
[in] pid
Specifies a packet identifier (PID), indicating which packets in the transport stream are requested.
[in] tid
Specifies a table identifier (TID), indicating which table sections to retrieve.
[in] pFilter
Optional pointer to an MPEG2_FILTER structure. The caller can use this parameter to exclude packets based on additional MPEG-2 header fields. This parameter can be NULL.
[in] hDataReadyEvent
Handle to an event. The filter signals this event whenever it receives new data.
