STREAM_ID_MAP Structure

The STREAM_ID_MAP structure 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:

Define Value
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.

Requirements
