IAMChannelInfo interface (qnetwork.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IAMChannelInfo interface gets and sets channel information for Windows Media Station (.nsc) files.
This interface is exposed by the Windows Media Source filter only when the filter is reading Windows Media Station (.nsc) files. The Windows Media Source filter uses .nsc files to get the information it needs to receive multicast content over the Internet. These files contain information such as stream location and rollover URL, as well as descriptive information about the station.
