IWMPNetwork::put_maxBandwidth
The put_maxBandwidth method specifies the maximum allowed bandwidth.
Syntax
Parameters
lMaxBandwidth
[in] long containing the max bandwidth.
Return Values
The 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
This method does not have a default value. The value can be specified while Windows Media Player is playing, but the change will not take effect until the current media item is released by opening another one or by calling ** IWMPCore::close. Windows Media Player attempts to achieve the highest bandwidth possible. Only in the case of this value being set will any intentional reduction of bandwidth occur.
This setting is useful for reducing the amount of bandwidth used, particularly in the case of a multiple bit rate (MBR) stream. An MBR stream contains multiple streams with different bit rates. In some cases, it may be desirable to use a stream with a lower bit rate than the client requires. In this case, specifying a lower bit rate with the IWMPNetwork::put_maxBandwidth method will select a lower bit-rate stream. For example, an MBR stream might include streams encoded at 20 kilobits per second (Kbps), 37 Kbps, and 200 Kbps. Using IWMPNetwork::put_maxBandwidth to specify a bit rate of 50,000 (50 Kbps) will select the 37 Kbps stream instead of the 200 Kbps stream.
