Hi Jean-Francois I can confirm that GSPCA v2.15.1 removes the bad pixels when I use Cheese or VLC. However, I'm sorry to report that the Motion problems unfortunately still remain. Is there something else I must do to overcome the below errors? I'm happy to keep testing newer GSPCA versions for you until we get this fixed. `--> tail /var/log/kernel.log Mar 5 08:25:52 Desktop kernel: [ 6673.781987] gspca_main: frame overflow 156309 > 155648 Mar 5 08:25:52 Desktop kernel: [ 6673.813992] gspca_main: frame overflow 156309 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6673.849986] gspca_main: frame overflow 155693 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6673.881989] gspca_main: frame overflow 156021 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6673.917991] gspca_main: frame overflow 156309 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6673.949993] gspca_main: frame overflow 156309 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6673.985990] gspca_main: frame overflow 156309 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6674.021981] gspca_main: frame overflow 156309 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6674.053985] gspca_main: frame overflow 156309 > 155648 Mar 5 08:25:53 Desktop kernel: [ 6674.089989] gspca_main: frame overflow 156309 > 155648 `--> tail /var/log/errors.log Mar 5 08:24:16 Desktop motion: [1] v4l2_next: VIDIOC_QBUF: Invalid argument Mar 5 08:24:16 Desktop motion: [1] Video device fatal error - Closing video device Mar 5 08:24:20 Desktop motion: [1] Retrying until successful connection with camera Mar 5 08:24:27 Desktop motion: [1] v4l2_next: VIDIOC_DQBUF: EIO (s->pframe 3): Input/output error Mar 5 08:24:27 Desktop motion: [1] v4l2_next: VIDIOC_QBUF: Invalid argument Mar 5 08:24:27 Desktop motion: [1] Video device fatal error - Closing video device Mar 5 08:24:30 Desktop motion: [1] Retrying until successful connection with camera Mar 5 08:24:33 Desktop motion: [1] v4l2_next: VIDIOC_DQBUF: EIO (s->pframe 0): Input/output error Mar 5 08:24:33 Desktop motion: [1] v4l2_next: VIDIOC_QBUF: Invalid argument Mar 5 08:24:33 Desktop motion: [1] Video device fatal error - Closing video device -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
