Here is how to install 0.12.5 version in case you would not be familiar with this : # log in as root You may have to build and install either 0.9.1 or 0.12.5 version. V4l2loopback sink may only support a subset of jpeg encoding, especially colorspace and sof marker.īeforehand, if running R32.6, the v4l2loopback-dkms packaged version 0.10.0 may not work properly for this case (seems 0.10.0 is working with R32.5.1, though). Maybe this could be of some use to somebody.Īt this point, I’ve decided to go a different route. Gst-launch-1.0 videotestsrc ! ‘video/x-raw, format=(string)I420, framerate=(fraction)30/1’ ! v4l2sink device=/dev/video1 The build from source is giving me new problems.

I have built v4l2loopback from source, and I’m still getting same error.
