[Solved] Webcam upside down, LD_PRELOAD no longer works.

SOLVED !
Need to remove libcamera and use LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4lconvert.so.0 cheese.

Hello I have Asus Laptop (PRO36S) issued around 2011. I remember around June 2023 (I used sid) I got upside down webcam and still solveable by using :

Code: Select all

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4lconvert.so.0 cheese

.

Going back until now, The LD_PRELOAD way is no longer works, even when I decided to move to ubuntu, It's still doesn't work. I have a thought that maybe I can use v4l-utils from June 2023 and maybe uvcvideo driver from that time. Is it possible ? Thanks.

Hello,

Perhaps this could be useful:

• LD_PRELOAD does not work and LD_DEBUG shows nothing

Hope this helps.
