The framerate of my USB 2.0 webcam is incredibly low. Perhaps it's because kamoso is streaming raw data rather than a compressed format? If so, it would be nice to have the option to select which format/fps to stream in.

Can reproduce on Fedora 35.
Comment 2 Patrick Silva 2021-12-17 19:22:11 UTC
Same thing on neon unstable installed on my laptop with an built-in webcam.
Cheese webcam app installed on the same system has correct fps.
Comment 3 Bohdan Mart 2022-12-25 23:49:47 UTC
Same problem on Manjaro.

Operating System: Manjaro Linux
KDE Plasma Version: 5.26.4
Qt Version: 5.15.7
KDE Frameworks Version: 5.15.84-1-MANJARO

Hardware: Acer Nitro 17 laptop

And I can confirm Patrick's observation, that Cheese works fast. Sad, because this is app from competitor -- Gnome.


I've also noticed same problem few year ago on my old DELL laptop and Kubuntu.

And Skype/Slack/Zoom didn't produce same slowness effect. (on old system and new system)
(and OBS as well, as I just checked today)

I would say to increase importance, as it makes this app unusable on some(?) systems.

On my experience it was 2 of 2 laptops I have in my possession. And competitors -- Gnome app works flawlesly.

I have the same issue and I think that, at least for my webcam it is because Kamoso sets the Pixel Format to YUYV when the native mode of my camera is MJPG.

In other webcam software that lets me choose the format, in YUYV shows the same slownes, but changing it to MJPG works fine.

There should be an option in Kamoso to set it, and ideally that would be saved in the config file

this is still issue with v24.02.x on openSUSE kalpa (flatpak pkgs), tried with the ProXtend XSTREAM 2K Webcam
