I have set some warnings in case this fails and like Hans said it works fine with the last gspca, but it fails for uvc with EINVAL in 2.6.31 kernel. I'm using the same v4l2_requestbuffers struct that I use for the first ioctl(VIDIOC_REQBUFS) ( type = V4L2_BUF_TYPE_VIDEO_CAPTURE and memory = V4L2_MEMORY_MMAP) but with count field set to 0. This is done after ioctl(VIDIOC_STREAMOFF) and munmap() Am I missing something here?
