I'm using the ISP drivers and MT9V032 driver from 
git://linuxtv.org/pinchartl/media.git head=media-0006-sensors. My kernel 
is 2.6.36.

This is my setup script:

    #!/bin/sh

    ./media-ctl -r;
    ./media-ctl -l '"mt9v032 3-005c":0->"OMAP3 ISP CCDC":0[1]';
    ./media-ctl -l '"OMAP3 ISP CCDC":2->"OMAP3 ISP preview":0[1]';
    ./media-ctl -l '"OMAP3 ISP preview":1->"OMAP3 ISP resizer":0[1]';
    ./media-ctl -l '"OMAP3 ISP resizer":1->"OMAP3 ISP resizer output":0[1]';
    ./media-ctl -f '"mt9v032 3-005c":0[SGRBG10 752x480]';
    ./media-ctl -f '"OMAP3 ISP CCDC":2[SGRBG10 752x480]';
    ./media-ctl -f '"OMAP3 ISP preview":0[SGRBG10 752x480]';
    ./media-ctl -f '"OMAP3 ISP preview":1[YUYV 752x480]';
    ./media-ctl -f '"OMAP3 ISP resizer":1[YUYV 1024x768]';

Which gives me:

Not sure whether this is a driver problem or...

Hi Neil,

I'm currently facing a similar problem than yours. Did you get a piece a
solution, to finally capture some video?

I'm using Laurent Pinchart's media-sensors git repository ( 2.6.37 ), and I'm
trying to capture some video provided by a saa7113 device.
