VAUX Source Control (VSC) Pack
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 following tables list the values used by the MSDV driver to fill in the dwDVVAuxCtl member of the DVINFO structure. For more information, see DVINFO Field Settings in the MSDV Driver.
