I'm using a driver which I got from the following link: http://lwn.net/Articles/308358/ I've modified the driver by inserting printk statements in the driver code to understand the flow of control between functions. I've also changed the arguments passed to the 'sccb_reg_write' function to values corresponding to the ov10620 sensor. I'm using a v4l2 example code as my application along with the above mentioned driver. The example code can be found at the below link: http://v4l2spec.bytesex.org/spec/capture-example.html When I run the application after inserting the driver, it calls the open_device(), init_device() and start_capturing() functions and then enters the mainloop() function. In the mainloop() function, the select() function call times out after 2 seconds and I'm not able to capture any video frames. I'm also receiving some errors like: gspca: ISOC data error: [3] len=56, status=-71 gspca: ISOC data error: [4] len=12, status=-71 This repeats with different values for 'len' and the value in [ ]. Any solutions?? ----- Regards, Sudhindra Nayak -- View this message in context: http://video4linux-list.1448896.n2.nabble.com/Not-able-to-capture-video-frames-tp5354598p5354598.html Sent from the video4linux-list mailing list archive at Nabble.com. -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request@redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list
