Update, I can flip my webcam using this : LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l2convert.so cheese
That command won't work if libcamera is installed. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to v4l-utils in Ubuntu. https://bugs.launchpad.net/bugs/2063828 Title: v4l-utils failed to flip upside down webcam. Status in v4l-utils package in Ubuntu: New Bug description: About a year ago (June 2023) I can flip my upside down webcam using LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4lconvert.so.0 <webcam_app>.
