DirectShow RGB-YUV filter

I would like to encode video in my app with VP8. I use RGB24 format in my app but VP8 DirectShow filter accepts only YUV format (http://www.webmproj开发者_StackOverflowect.org/tools/#directshow_filters).

I've googled the "RGB to YUV directshow filter" but no success. I don't want to write this filter myself from scratch, so I would appreciate if you help me with the information on where to find such filter.

Thanks!

You could try Geraint Davies' YUV transform filter to see if it supports the conversion.

Starting from Vista you can use Color Converter DSP, does this help?

If you know how to implement a transform filter, I have a fast YUV to RGB algorithm somewhere. I used DirectShow a looong time ago, so I can't be of anymore help than this :P
