After installing Nvidia drivers 340xxx on CentOS, Videos are not playing in vlc and smplayer. It plays on Totem Movie Player though.
Code:

Before installing Nvidia drivers, all working fine.
Sorry, wrong file name, should have been libOpenCL.so.1.0.0. Fixed in my post above.
Nope.

Also, there's a tool, clinfo, that shows properties of OpenCL. Either build it yourself, or download and install the package I prepared. You'll also need to install xorg-x11-drv-nvidia-340xx-cuda. Then show the output of clinfo -l and, if it fails,
Code:
find /etc/OpenCL/vendors/ -name \*.icd |
while read clpath
do clinfo -l >/dev/null; echo "$? $clpath"
done
In the meanwhile I’ve solved (just a nightmare workaround) removing some applications like ffmpeg, openshot, vlc and their related libs from my fc28 system and reinstalling the same applications and libs downloaded from fc27 repos. All is working good now but we hope next 340 driver will give opencl 1.2 support, like nouveau driver do.
I guess instead of removing they could be rebuilt from their .src.rpm against appropriate libOpenCL.
I have installed nvidia driver from the official website with file 'NVIDIA-Linux-x86_64-340.108.run'. I'll now try installing from rpmfusion and see what happens.
I installed clinfo.rpm you have posted. following is the output.

Unfortunately the same results. Reinstalled CentOS 8.1, installed Nvidia drivers from rpmfusion with no luck. Dont know what to do. I need Nvidia drivers to run SlowmoVideo in V3D flowbuilder rendering.
work now though? I was of impression you had RPM Fusion package, so didn't check if the path was right.

Tried for 2 straight days to make Nvidia work on CentOS 8.1. Tried all types - driver from Nvidia website, akmod-nvidia, and kmod-nvidia with flop results. What a waste of time. Fed up with Nvidia drivers. Nvidia can go to hell.
Now, after going through tons of websites, I came up with this - hardware acceleration through nouveau.
Code:
$ sudo dnf install mesa-dri-drivers mesa-vdpau-drivers vdpauinfo
$ sudo cat /etc/environment
VDPAU_DRIVER=nouveau
$ sudo ln -s /usr/lib64/vdpau /usr/lib/vdpau

Good news is video is rendering with hardware acceleration, bad news is it takes at least 4-10 times more time to render. A typical 10-second video in slowmovideo with nvidia driver would take 20+ minutes, whereas with nouveau driver rendering it takes 2+ hours to do the same.
