A few of them can be printed when starting video capture, the driver just needs to synchronize to the video stream. Release 6.3.16 05/10/2012 DC - Update firmware for VisionAV. - Report detected and current video timings. Release beta 7.2.0 17/06/2013 DC - Implement vidioc_default ioctl to handle private VIDIOC_G_FMT calls to retrieve source resolution. - Use latest firmware and flash (rev48) images. When the buffer is intended for output (type is V4L2_BUF_TYPE_VIDEO_OUTPUT, V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE, or V4L2_BUF_TYPE_VBI_OUTPUT) applications must also initialize the bytesused, field and timestamp fields, see the section called “Buffers” for details. http://www.hitl.washington.edu/artoolkit/mail-archive/message-thread-01943--ARToolKit--error--acqui.html

I have a much better understanding now. MAYANK AGARWALAre you able to overcome your issue and get the captured image. The linuxtv version defaults to video0.

You have to pass the device name as a parameter as such: ./v4l2capture.out -d /dev/video0. I applied a patch to add support for Video 4 Linux 2 devices into the artoolkit based on the artk 2.72.1 tarball. If error loop all index and try. Vidioc_dqbuf No Such Device When VIDIOC_QBUF is called with a pointer to this structure the driver sets the V4L2_BUF_FLAG_QUEUED flag and clears the V4L2_BUF_FLAG_MAPPED and V4L2_BUF_FLAG_DONE flags in the flags field, or it returns an

Struct V4l2_buffer

Note that I only use the terms frontend and backend here for clarity (separation of logic and driver-specific code). https://linuxtv.org/downloads/v4l-dvb-apis/vidioc-qbuf.html Can be set by modifying options in modprobe.conf.

In that case the application should be able to safely reuse the buffer and continue streaming. I found one big differense between this cards, and it is how they handle when I disconnect a camera. And I have replaced printf statements with motion_log. Fixed the compilation issues of Jan Rycter's patch. - Changed video.h definitions ( remove some function headers ) - Moved functions in video.c - Fixed gcc-4.x compilation issue. - Check first
