Linux V4L/V4L2 driver for FujiFilm FinePix digital cameras in PC-CAM (WebCam) mode. This driver has been integrated in the linuxkernel 2.6.28. So this project is now dead and unmaintained, although I still maintain the one in the kernel.
Superseded by the GSPCA driver in the mainline kernel. Development now at http://linuxtv.org/ [Formerly: Linux device driver for SPCA50X based USB cameras (Intel PC Camera Pro)]
Java access to USB, currently using kernel 2.4 Linux-USB support. There is a "core" API for accessing USB devices, and simple tools including a USB viewer in Swing. Applications are being developed separately, including digital camera support.
Auth0 Token Vault handles secure token storage, exchange, and refresh for external providers so you don't have to build it yourself.
Rolling your own OAuth token storage can be a security liability. Token Vault securely stores access and refresh tokens from federated providers and handles exchange and renewal automatically. Connected accounts, refresh exchange, and privileged worker flows included.
