VGA 16 Color Ditherer Filter
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 VGA 16 Color Ditherer filter converts from an RGB color type to a 4-bit color display so that AVI and MPEG video streams may be displayed on older 16-color monitors. This filter is inserted in the graph between a decompressor filter and a video renderer filter.
