This is not a opencv or ice error. As you can see is a video4linux
(or module/driver) error.<br>

The patch was enough, but there is a problem with your webcam and/or
USB bus.<br>
<br>
Try the same fix that I told in another thread:<br>
<br>
sudo rmmod uvcvideo<br>
sudo modprobe uvcvideo nodrop=1<br>
<br>
If it is not enough then try this:<br>
<br>
<meta http-equiv="content-type" content="text/html;
charset=windows-1252">
sudo rmmod uvcvideo<br>
sudo modprobe uvcvideo timeout=10000 quirks=0x80 nodrop=1<br>
<br>
If it fixed your problem you can do them permanently with:<br>
<br>
echo "uvcvideo timeout=10000 quirks=0x80 nodrop=1" | sudo tee -a
/etc/modprobe.d/jderobot_workarround.conf<br>
<br>
Almost all my problems with webcams in the GK802 and Raspberry was
fixed with that line.<br>
<br>
Best regards.<br>
