IActiveBasicDevice::GetEffectiveBandwidth method (windows.media.streaming.h)

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 It has been superseded by Media Casting.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