ambilight

[brutus]

Is there a way to calculate the average rgb value of the screen in overlay mode ?

 

For my www.arfx.nl system running in evr/vmr (default/custom) it works out of the box but the image is not stable (tearing/blocking).

I tried all beta versions, xp, win7 , no success.

 

If I could retrieve the rgb of the screen in overlay mode then I could program this value to the arfx module via the sdk.

A screencapture in overlay mode results in a blackscreen, so a hook into the DVBViewer might be required to obtain access to the screen information.

Via a postprocessor plugin, directshow filter, something else ?

 

Any help would be welcome!

DVBViewer doesn't handle and doesn't access the (decoded) picture data in overlay mode. It all happens within the DirectShow filter graph and graphics card.

 

Via a postprocessor plugin, directshow filter,

A DirectShow filter inserted between the video decoder and overlay mixer could access the picture data. It would disable hardware-accelerated decoding, however.
