Hello,
I tried to capture an image from my ov3640 camera sensor with the media-ctl
and the yavta tool. But I got "UNable to start streaming:Invalid argument(22)."
Does anyone know what I did wrong?
What I did:
root@overo2:~/media_test/bin# sudo ./media-ctl -p -r -l '"ov3640
3-003c":0->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC
output":0[1]'
