Unable to use CUDA decoder

Yup, confident I didn’t overwrite /lib/x86_64-linux-gnu/libnvcuvid.so. I just checked again to confirm:

% ls -l /lib/x86_64-linux-gnu/libnvcuvid* 
lrwxrwxrwx 1 root root   15 Jan  9 04:06 /lib/x86_64-linux-gnu/libnvcuvid.so -> libnvcuvid.so.1
lrwxrwxrwx 1 root root   23 Jan  9 04:06 /lib/x86_64-linux-gnu/libnvcuvid.so.1 -> libnvcuvid.so.545.29.06
-rw-r--r-- 1 root root 3528 Apr  1 00:01 /lib/x86_64-linux-gnu/libnvcuvid.so.545.29.06

Looks like /lib/x86_64-linux-gnu/libnvcuvid.so and /lib/x86_64-linux-gnu/libnvcuvid.so.1 are linked to /lib/x86_64-linux-gnu/libnvcuvid.so.545.29.06 as expected.

And no, I didn’t copy the stubs into the CUDA toolkit directory in /usr/local either.

And here’s what you asked for:

% cat ~/build/opencv/build/CMakeVars.txt | grep CUDA_nvcuvid_LIBRARY 
CUDA_nvcuvid_LIBRARY=/lib/x86_64-linux-gnu/libnvcuvid.so

And I acknowledge your note about CMake being able to automatically pick up the location of libnvcuvid.so.1. I guess I got a bit paranoid about it after the series of attempts at building OpenCV to get the CUDA decoder to work.

Cheers!
