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?

Probably because it still uses the android camera API to do so rather than directly access /dev/video0.

I'm sure it is possible to add a video capture to the API 😉

Yeah, I mean it's not like they're calling native Android functions there (in proceedWithOpenCamera), it looks like the CameraDevice object might offer a lot more capture modes that just aren't being tapped into. Is it just a programming issue, or does Android only offer Photo contexts but not Video ones, or...?
