Hi Atsuo Igarashi,
I am trying the same patch on my beagle board. i am using android kernel
2.6.29.
my usb webcam is not uvc. my resolution is 320x240.
my webcam is v4l2. it got detected and using v4l-info i can see it.
when i click the camcorder application, only green colour or some random
dotted pixels coming.
Is there any thing other than this patch, we have to put for beagleboard.
Thanks and Regards,
HarishKumar.V
