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.

UVC Viewer with Upscaling (lemmy.yachts)

I have a UVC capture card that I use to play my Switch. Currently, I utilize it via the full screen projector feature of OBS, but the Switch is 1080p while my monitor is 4k and the upscaling that OBS uses causes some noticeable artifacts.

I’m wondering if there’s an application with some configurable upscaling options that would make this experience better. I don’t need anything crazy that would cause noticeable input lag, but anything even slightly better than OBS would be welcome

As I understand you take in some stream video akin to /dev/video0 and want to enlarge it so you can look at your monitor while playing? Whenever it is something with video ffmpeg can probably solve it. FFmpeg flags like -vf also work on the video player, ffplay.

At the bottom they talk about choosing scaling algorithms, try some out to see what combination of quality and speed you get.
