| - | The libcamera utilities are installed on Vizy and in the shell search path (libcamera-vid, libcamera-still, etc). The advantage of using these utiltiies instead of the older ones is that libcamera offers better performance (significantly better images) over the older utilities and it’s more modular for mixing in customizations. | + | This will stop the Vizy server. (To run the server again, either reboot or run ''%%sudo systemctl start vizy-server%%''). You'll also want to [[wiki:connect_monitor_etc|hook Vizy to a monitor]], as most utilities preview the video through the monitor. |

| + | |||
| + | If you want to go back to the legacy utilities, you can change ''/boot/config.txt'' by commenting out the line that says ''%%dtoverlay=imx477%%'' and rebooting. You can then run ''raspivid'', ''raspistill'', etc., which are also installed. However, when you make this change to config.txt, the Vizy server/software will no longer be able to get camera data and will likely give up and exit. | ||
