Describes the indexing configuration for a stream and type of index.

Syntax

typedef struct _ASF_INDEX_DESCRIPTOR {
  ASF_INDEX_IDENTIFIER Identifier;
  WORD                 cPerEntryBytes;
  WCHAR                szDescription[32];
  DWORD                dwInterval;
} ASF_INDEX_DESCRIPTOR;

Members

Identifier

ASF_INDEX_IDENTIFIER structure that identifies the stream number and the type of index.

cPerEntryBytes

Number of bytes used for each index entry. If the value is MFASFINDEXER_PER_ENTRY_BYTES_DYNAMIC, the index entries have variable size.

szDescription[32]
