AVISUPERINDEX structure
Contains an AVI 2.0 super index (index of indexes).
Syntax
typedef struct _avisuperindex {
FOURCC fcc;
UINT cb;
WORD wLongsPerEntry;
BYTE bIndexSubType;
BYTE bIndexType;
DWORD nEntriesInUse;
DWORD dwChunkId;
DWORD dwReserved[3];
struct {
DWORDLONG qwOffset;
DWORD dwSize;
DWORD dwDuration;
} _avisuperindex_entry;
_avisuperindex_entry aIndex[NUMINDEX(4)];
} AVISUPERINDEX;
Members
fcc
A FOURCC code. The value must be 'indx'.
cb
The size of the structure, not including the initial 8 bytes.
wLongsPerEntry
The size of each index entry, in 4-byte units. The value must be 4.
bIndexSubType
The index subtype. The value must be zero or AVI_INDEX_SUB_2FIELD.
bIndexType
The index type. The value must be AVI_INDEX_OF_INDEXES.
nEntriesInUse
The number of valid entries in the adwIndex array.
dwChunkId
A FOURCC that identifies the object that is indexed.
dwReserved
Reserved. Set the array elements to zero.
_avisuperindex_entry
_avisuperindex_entry.qwOffset
_avisuperindex_entry.dwSize
_avisuperindex_entry.dwDuration
aIndex
An array of structures that contain the following members. The number of elements in the array is calculated from the value of cb.
qwOffset
The offset, in bytes, from the start of the file to the sub-index that this entry points to.
dwSize
The size of the sub-index, in bytes.
dwDuration
The duration of the file that is covered by the sub-index, in stream ticks.
