Color Space Converter Filter

  • 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

This transform filter converts from one RGB color type to another RGB type, such as between 24-bit and 8-bit RGB color. Since this type of conversion is generally handled more efficiently within a video decompressor, the main use of the Color Space Converter is when the stream source consists of uncompressed RGB frames.
