Re: SVP 4 Linux

SVP doesn´t detect my Nvidia GTX 1060 GPU in Manjaro Linux, I can´t set GPU acceleration but in Windows I can. Why is that? I installed Nvidia Drivers and GPU works fine with games, what  should I do in order to get GPU acceleration in SVP?, didn´t it work in Linux? then why is the option there?

Re: SVP 4 Linux

should I install both? what is this?, if it is nvidia-utils I already have it, I installed the propietary drivers, but svp still doesn´t detect it

Re: SVP 4 Linux

Prerequisites
6. (recommended) Proprietary video drivers including OpenCL ICD

For GPU acceleration support use proprietary video drivers with (probably) some additional modules - search for "OpenCL ICD". For example in case of NV cards "nvidia-modprobe" package is needed for OpenCL to work. Check the installation with utils/clinfo.

Re: SVP 4 Linux

Ok, I solved it, thank you.

I installed GPU-viewer and I saw that opencl was not installed, so I installed it throw pacman with the package opencl-nvidia.

Re: SVP 4 Linux

Linux noob here, running Xubuntu 18.04.1.
I'm having trouble giving SVP write permission for VLC's video_filter folder.

I run

sudo chmod 777 /usr/lib/x86_64-linux-gnu/vlc/plugins/video_filter

in the console and it appears to work fine - no errors or other messages.
But every time I try to activate "SVP in VLC (replace 'deinterlace' filter)" in SVP's menu, I get this error:

Operation failed. Check that SVP Manager has write access to '/usr/lib/x86_64-linux-gnu/vlc/plugins/video_filter/video_filter'.

What am I doing wrong?

Re: SVP 4 Linux

'chmod -R' probably

234

Re: SVP 4 Linux

Still no go.
I also tried "-R a+rwx". Properties for the folder and files inside show Read&Write permissions for everyone, but SVP still gives the same error.

Re: SVP 4 Linux

why '/usr/lib/x86_64-linux-gnu/vlc/plugins/video_filter/video_filter' ("video_filter" written twice)?
is it your typo when copying text?
check 'main.setup.vlc.plugins' value in "All settings", it must be equal to "/usr/lib/x86_64-linux-gnu/vlc/plugins"

Re: SVP 4 Linux

Damn, I'm stupid. I entered the full path to filters instead of plugins and didn't even notice it in the error message.

Thanks, now it's working.

Re: SVP 4 Linux

As a minor follow-up to what I said on the previous page about propietary vs open drivers for getting OpenCL GPU acceleration on AMD and Intel GPUs, I can at least confirm that on Mint 19.1 (and therefore presumably anything based on Ubuntu 18.04) that all I had to do was install "mesa-opencl-icd" and, specifically for my Intel Haswell iGPU, "beignet-opencl-icd" through my OS's package manager.

And that was it - I was then able to use my Intel iGPU to accelerate SVP without seemingly any issue whatsoever and performance was then comparable to what I get in Windows with the same hardware configuration and customized SVP interpolation profile settings (I also confirmed that disabling GPU acceleration absolutely tanked my performance).



----------------------------------------------------------------


You know, the Linux page on the wiki could probably use a bit of a cleanup - an easy example is that one needs to use libass9 nowadays instead of libass5.

Also the process for getting SVP working on at least Linux Mint 19.1 (and therefore presumably any distro based on Ubuntu 18.04) seems to be much less involved than the wiki makes it out to be.  From my totally-not-in-depth testing, it seems like all one needs to do is run the following four commands individually before running the SVP installer, and then you'll be good to go:

sudo add-apt-repository ppa:deadsnakes/ppa

sudo add-apt-repository ppa:djcj/vapoursynth

sudo apt-get update

sudo apt-get install libqt5concurrent5 libqt5qml5 libpython3.5 mediainfo mpv libqt5svg5 libass9

Now I don't know what goes into the process of making a .deb, but I do know that other software distrobuted as .deb, like MEGAsync, will automatically install the required dependencies before installing the according program, and I can't help but think that something like that could be useful here.



And of course, like I stated, I was then also able to just use the following command to get GPU acceleration in SVP on my Haswell Intel graphics (this supposedly would work for Intel Ivy Bridge graphics as well and maybe even Intel Sandy Bridge graphics):

sudo apt-get install mesa-opencl-icd beignet-opencl-icd

I believe the "mesa-opencl-icd" would also be used for AMD GPUs, but at this time I don't know what (if anything) would be the AMD GPU equivalent to beignet-opencl-icd.



EDIT: While playing with things a little farther, I did notice something interesting - if I open a video file with SVP, then it'll play in mpv with SVP's interpolation active like usual.  If I open a video file in mpv directly, it will play in in mpv without SVP's interpolation being active.

Is this the expected behavior?  I mean, I only have a single installation of mpv installed since this was tested on a completely fresh installation of Linux Mint 19.1 Cinnamon 64bit.

Re: SVP 4 Linux

mpv.conf is the key for your last question

Re: SVP 4 Linux

So similar to what I've mentioned in my "OpenCL minimum requirement" thread, is it accurate to say that, for AMD graphics, the minimum requirement to use SVP's GPU acceleration (without going all the way back to Ubuntu 14.04) would be the Radeon HD7000 series?

Re: SVP 4 Linux

I really have no idea. If you post a clinfo's output for a pre-7000 card in Linux, I'll tell why it's not supported in SVP.

Now is that the only thing missing on the list that would be required?

I just want to make sure before I go doing any more research only to discover "but wait, there's more!".

Re: SVP 4 Linux

Been using SVP for quite some time but now I moved to Manjaro Linux and I have no clue what to do with the error that the deinterlaced filter for VLC is not available? Am I missing anything or is it just not possible at the time to use SVP and VLC?

Re: SVP 4 Linux

it's not error but an information message meaning "deinterlace filter replaced with SVP's filter, you can't use deinterlacing now"

Re: SVP 4 Linux

Really? Well, it doesn't sound like it: "SVP support ENABLED but the deinterlaced filter in VLC is not available any more." And it's not working btw. Appreciate the support though!

Re: SVP 4 Linux

what exactly it sounds like? hmm

What doesn't work: SVP or deinterlace? Deinterlace shouldn't but SVP should.

Re: SVP 4 Linux

Has anyone tested the ROCm OpenCL runtime (https://github.com/RadeonOpenCompute/RO … CL-Runtime) and made it work with SVP? I installed it recently but SVP failed to detect my GPU as a supported device when using the ROCm runtime.  I'm running on Manjaro Linux 18 .

This is the my clinfo output. I have installed 2 OpenCL runtime from AMD:

1) OpenCL driver extracted from the proprietary AMDGPU-PRO driver (https://aur.archlinux.org/packages/opencl-amd/) - The one I can only use
2) OpenCL driver provided by ROCm OpenCL runtime ((https://github.com/RadeonOpenCompute/RO … CL-Runtime) - The one I'm trying to use
