Retrieves the current size of the buffer in bits.
Syntax
HRESULT GetBufferSizeBits(
[out] ULONG *pulBufferSize
);
Parameters
- pulBufferSize [out]
Pointer to a variable containing the buffer size, in bits.
Return Value
This method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
| S_OK | The method succeeded. |
Remarks
The buffer size is equal to the bit rate of the stream multiplied by the buffer window. For example, a stream with a bit rate of 28 kilobits per second with a buffer window of 3 seconds would have a buffer of 28000 bits per second x 3 seconds = 84000 bits.
