After “apt-cache search libuvc”,“dpkg -l libuvc-dev”, " dpkg -l libuvc0", “apt list | grep libuvc”, "apt list --installed | grep libuvc"command , the result is the same as yours.
and is it correct to check my firmware using the dmidecode command? maybe… 4.1 version.
I try to unmount Theta as filesystem following the manual you sent me and theta z1 camera recognized in gphoto2.
and ./gst_loopback can run!! thanks. but…
I see that example python file you sent doesn’t work. so I still don’t solve not operating camera z1 in opencv associated with v4l2…
