IAMVfwCompressDialogs interface (strmif.h)

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IAMVfwCompressDialogs interface displays a dialog box provided by a Video for Windows (VFW) codec. The AVI Compressor filter implements this interface. Applications can use it to display one of the dialog boxes (Configure or About) provided by VFW codecs, and to set and retrieve compressor status.
