[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The ASFLeakyBucketPairs attribute is an optional attribute that describes the buffering requirements for a variable bit rate file.

{
    WORD wReserved;
    WM_LEAKY_BUCKET_PAIR bucket[2];
};

Where wReserved must equal zero, and bucket is an array of WM_LEAKY_BUCKET_PAIR structures. The array must contain at least two entries, but can be larger. The reader object uses this attribute to determine the amount of content to buffer before playback.
