Hi, I'm not 100% sure this is a problem with the v4l2sink, but the preview in obs looks fine and the video has some serious color shifts in any tool I try to display the v4l2loopack I'm directing the sink to. View from OBS: View from OBS View from Browser: View from Browser You can see that all colors have a green shadow about half the grid width. Is there any setting that I could change to fix this? I tried playing with the output resolution, as this looks similar to Issue#45, but that didn't help. The video format selected in the V4l2sinkProperties is YUV420 as all others result in "format not supported"

Switching to YUY2 fixed color glitch for me.

Did you really try using the resolution 704x396? It worked for me...

@ochen1 didn't work.

Same here. Colors are shift in v4l2loopback out. There are not other video mode in V4l2sinkProperties.

Solved here in KDE Neon 5.20 (Ubuntu 20.04) removing libv4l2rds0 package. After this, the YUY2 video mode works and the image colors stay ok.
