This patch has been added to 0.3 release..

This will give you the 640x480 image scaled down to the image size requested from a client v4l app.

It's pretty raw (increases CPU by 10%-20% on my Athlon-xp2600 and only supports RGB24) but it works.

I'm currently using it for Gnomemeeting's 352x288 and 176x144 video modes and have had only a couple minor glitches but no kernel panics.

Here's the link -> http://projects.stuartrharper.net/OV519-scaler.patch.bz2

It should apply cleanly to the source from this site. While inside the modules' source directory, fire off this command: 

 bzcat OV519-scaler.patch.bz2 | patch -p1

Make, install, depmod -a and modprobe ov519_decomp, attach the camera, and you're good to go.

Downscaling update

This patch has been added to version 0.4!

Here's an updated patch for downscaling the OV519 output. I've replaced the RGB24 scaler with a YUV420P scaler. This restores the support for formats other than RGB24 as well as lowering the CPU load by 5%.

The patch is against ov51x-jpeg-0.3
