Dear everyone: I wonder why v4l2 driver cancel all the urbs in VIDIOC_S_FMT and then reinit all the urbs to submit. VIDIOC_S_FMT only negotiate frame format with application like mplayer and has nothing to do with our v4l2 driver. And in my driver I follow the way most drivers have taken, but when I use usb_submit_urb() in VIDIOC_S_FMT to submit all the urbs successfully reinited, my Ubuntu crashes. Caps and Scroll flash during my Ubuntu crashes. I can't get any value message from my syslog. Could somebody help me with this issue? Thank you in advance! _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
