Turn off dithering in Color Space Converter Filter

[Andrew Branch]

Hi,

I'm using the Color Space Converter filter to convert an RGB32 video
stream to RGB8. I would like to configure it, and turn off the
dithering. Is this possible? I don't see any interfaces to configure
it.

Thanks

I think dithering if function of Video Renderer not Color Space
Converter. So in any case it you use Old Video Renderer or VMR you may
find out about them interfaces in MSDN to achieve what you want

In this case, I know the video renderer is not dithering, because I
wrote it. The video renderer is sending out an RGB32 stream. The graph
is as follows:

[My Video Renderer] --RGB32--> [Color Space Converter] ---> [Microsoft
RLE] ---> [AVI Mux] ---> [File Writer]

The dithering must be in the Color Space Converter when it converts
from RGB32 to RGB8. If I can't configure the color space converter,
then my backup plan is to send an RGB8 stream, undithered, from my
video renderer. But I'm hoping for an easier way.

No it is not possible. BTW, the
microsoft.public.win32.programmer.directx.video is the appropriate newsgroup
for your post.
