STREAM_ID_MAP Structure

Structures

Describes an elementary stream within an MPEG-2 program stream. Used with the IEnumStreamIdMap interface methods.

Syntax

typedef struct {
    ULONG   stream_id;
    DWORD   dwMediaSampleContent;
    ULONG   ulSubstreamFilterValue;
    int     iDataOffset;
} STREAM_ID_MAP ;

Members

stream_id
Specifies the ID of the PES stream.
dwMediaSampleContent
Specifies the media contents of the stream. May be one of the following values (#defined in axextend.idl):
    MPEG2_PROGRAM_STREAM_MAP                 0x00000000
    MPEG2_PROGRAM_ELEMENTARY_STREAM          0x00000001
    MPEG2_PROGRAM_DIRECTORY_PES_PACKET       0x00000002
    MPEG2_PROGRAM_PACK_HEADER                0x00000003
    MPEG2_PROGRAM_PES_STREAM                 0x00000004
    MPEG2_PROGRAM_SYSTEM_HEADER              0x00000005
ulSubstreamFilterValue
Specifies the substream within the elementary stream. If no substream filtering is required, use SUBSTREAM_FILTER_VAL_NONE (0x10000000).
iDataOffset
Specifies the offset in bytes for the substream. If no filtering is required, specify 0.
