WM_LEAKY_BUCKET_PAIR structure

The WM_LEAKY_BUCKET_PAIR structure describes the buffering requirements for a VBR file. This structure is used with the ASFLeakyBucketPairs attribute.

Syntax


typedef struct _WMLeakyBucketPair {
  DWORD dwBitrate;
  DWORD msBufferWindow;
} WM_LEAKY_BUCKET_PAIR;

Members

dwBitrate

Bit rate, in bits per second.

msBufferWindow

Size of the buffer window, in milliseconds.

Remarks

The ASFLeakyBucketPairs attribute gives a list of bit rates and corresponding buffer windows. For each bit rate, the msBufferWindow member indicates how much content the reader object will buffer before it begins playback. The size of the buffer in bytes equals msBufferWinow x dwBitrate / 8000.
