Hi Javier, Can you run v4l2-compliance? I have updated it today so that it is able to handle m2m devices. It will find at least one problem since you didn't set bus_info in querycap :-) You will also see that it complains about VIDIOC_G_PARM. That's fixed by applying this patch: http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg49271.html That patch is part of a patch series that fixes mem2mem_testdev so that v4l2-compliance runs without errors.
