From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What are the limitations of accessing /dev/video0 on an android device? (lemmy.ml)

Conceptually I can understand that Termux cant take a photo or video from a camera device because it doesnt have access to the camera drivers that Android has....

...except that the Termux API does allow you to take a photo. So why is video off limits?

# ls -l /dev/video0
crw-rw---- 1 system camera 81,   0 1974-07-26 10:09 /dev/video0

Android doesn't handle users and groups like standard Linux, but the user account assigned to Termux is not a member of the camera group.

Is it just a permissions issue? On a rooted phone, could I not simply add termux user to the camera group

That seems likely to work.
