Which application can I use to test webcam? - tophneal - 01-31-2020
Camera works great in manjaro. I’ve tested with cheese. Didn’t count frame rate, but visually it was per decent.

It can also be tested with mpv with different settings. Although I think we all have same cameras it's worth to take a look at what it offers:
Code:
v4l2-ctl --list-formats-ext -d /dev/video3
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture
[0]: 'YUYV' (YUYV 4:2:2)
Size: Discrete 1280x720
Interval: Discrete 0.100s (10.000 fps)
Interval: Discrete 0.200s (5.000 fps)
Size: Discrete 1600x1200
Interval: Discrete 0.050s (20.000 fps)
Interval: Discrete 0.067s (15.000 fps)

Interval: Discrete 0.067s (15.000 fps)
Interval: Discrete 0.100s (10.000 fps)

Size: Discrete 320x240
Interval: Discrete 0.050s (20.000 fps)
Interval: Discrete 0.067s (15.000 fps)
Interval: Discrete 0.100s (10.000 fps)
Interval: Discrete 0.200s (5.000 fps)
Size: Discrete 800x600
Interval: Discrete 0.100s (10.000 fps)
Interval: Discrete 0.200s (5.000 fps)And then experiment with some settings. It's actually not that bad unless you are David Attenborough
For me - the best results are with following settings (--profile=low-latency is important).
Code:
mpv --demuxer-lavf-o=video_size=640x480:famerate=20 av://v4l2:/dev/video3 --profile=low-latency
