Hi all! this is my first post in this mailing list so I hope I'm not asking in the wrong place. I had an application based on this code: http://libv4l2cam.googlecode.com/svn/trunk/v4l2stereo/libcam.cpp working fine without problems, but since I updated my Ubuntu to the 10.04 (I suppose this is somehow related) it began to crash randomly with the following error: VIDIOC_QBUF error 22, Invalid argument I traced the error and it happens in the method Camera::Get() when using IO_METHOD_MMAP in the following lines: if (-1 == xioctl(fd, VIDIOC_QBUF, &buf)) errno_exit("VIDIOC_QBUF"); so when I try to read a frame from the camera. Any hint of what could be going wrong? Thank you very much.
