Im using OBS with v4l2sink and v4l2loopback to edit my video for a remote trainig. The preview in obs looks fine, but 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? The video format selected in the V4l2sinkProperties is YUV420 as all others result in "format not supported"

I run Ubuntu 20.04.1 LTS (Linux 5.4.0-42-generic x86_64). OBS Studio is 25.0.8 installed via apt. obs-v4l2sink and v4lsloopback are built and installed from the current GitHub sources.

You need to set the format to YUY2 and set the same dimensions on OBS and v4l2 device.

I solve my issue of "not supported format" by:

  1. removing v4l2loopback-utils and then installing v4l2loopback-dkms
  2. set YUY2 on v4l2sink menu
