Troubleshooting

When using Point Grey's GigE cameras, you may experience an issue with dropped packets which results in IMAGE_CONSISTENCY_ERROR being thrown by the FlyCapture2 SDK. You can adjust the receive buffer settings in Linux using sysctl to correct this. See this knowledge base article from Point Grey for more details.

Similarly, multiple USB cameras may require raising the amount of memory allocated to the USB subsystem. The usbcore variable usbfs_memory_mb should be set suitably large. This application note describes two common ways of setting it, via the kernel command line (edit /boot/grub.conf), or module loading (modprobe usbcore usbfs_memory_mb=1024 for current session, or adding options usbcore usbfs_memory_mb=1000 to an appropriate /etc/modprobe.d file). It should also be settable at runtime via /sys/module/usbcore/parameters/usbfs_memory_mb
