Hi all,
I'm trying to initialize the camera device and running into some
errors. I'm attempting to use the mmap interface initialized by
VIDIOCGMBUF ioctl. the ioctl is returning -1 and errno is 22.
Is VIDIOCGMBUF/mmap even supported by the driver/device? If so, any
ideas on what can be going wrong?
Here is the c++ code that is causing the problem:
video_mbuf mmap_buf_info;
if (-1 == ioctl(vidfd, VIDIOCGMBUF, &mmap_buf_info))
{
printf ("ERROR: %i \n", errno);
close();
return(HXR_ENC_NO_VIDEO_CAPTURE);
}
thanks,
-peter
