SVP 4 Linux (Page 13 of 19)

Hi, using void linux and mpv/smplayer.

Svp works great on the 5.8 kernel, but on 5.9 it does not detect my gtx 1080. It should not be the nvidia 5.9 problem since my steam games work fine with my gpu.
Tried reinstalling Svp, drivers etc. , nothing worked

I'm also trying to run it on nixos. I wrote all of the progress/details so far here: https://github.com/NixOS/nixpkgs/issues/64344

libsvpflow works, SVP Manager - same problem, "This option is not available. Please see --help for all possible usages". It comes from the 'zenity' - SVP Manager still fails even if it's not present through. I have no clue why.

As for error 255, it's about missing ocl-icd package -  and it needs to be specified in hardware.opengl.extraPackages list. That should put libOpenCL into /run/opengl-driver/lib.

Then libsvpflow needs to have that in it's rpath. In the linked github comment I've included "svpflow.nix" derivation: it only installs the libs without SVP Manager (which doesn't work), and they're available under /run/current-system/sw/lib/libsvpflow1_vs64.so (and the same for 2).

I've recently come into possession of an A8-7600 and have been trying and failing to get OpenCL GPU acceleration working on the newly-released Linux Mint 20.1. UPDATE: AMD's GPU driver selector on their website is a derp - the solution is to say your GPU is an R9 290X and just use the provided Ubuntu 20.04 drivers since the R9 290X uses the same GPU architecture, GCN2, as the A8-7600.

First off, even on a fresh OS installation, mpv+vapoursynth wouldn't compile unless I first installed harfbuzz from the package manager.  After that it all seemed to install fine...

...except that the ".run" file for SVP straight up wouldn't run as if it was a corrupt or incomplete file.  I even tried re-installing the snap store and even that didn't work.

But I was able to run it without issue around 2 years ago, so sure enough I was able to find an older version through archive.org that similarly "just worked", the key point being the archive itself is named "svp4-linux-64.tar.brz" without any version number as all the newer versions with the version number in the .tar.brz result in the "simply doesn't work", and from there I was able to just run the built-in updater to upgrade to whatever the latest version of SVP was:

https://web.archive.org/web/20190701200 … ux-64.tbz2

Once I got that installed, the issue was the thing I said at the top - I seem to be unable to get OpenCL GPU acceleration working.  I know historically you're supposed to install the proprietary driver, but it doesn't seem to support Ubuntu 20.04 LTS and derivative OSes (e.g. Linux Mint 20.x).  From what I can tell, including on the SVP wiki's page for Linux, you're supposed to use ROCm for OpenCL nowadays, and while it seemed like I was able to successfully install ROCm, it made no difference with regards to enabling OpenCL GPU support in SVP.

I tried to also follow a process to install only the OpenCL driver from the AMDGPU-PRO driver but...well, it pretty much borked up my video drivers altogether (it was a completely fresh OS install so doing another fresh OS install is no big deal).

So yeah uh, I'm not particularly concerned about the newest SVP installer not running at all, but I definitely want to get GPU OpenCL functioning and am hoping people have insight on the process. UPDATE: AMD's GPU driver selector on their website is a derp - the solution is to say your GPU is an R9 290X and just use the provided Ubuntu 20.04 drivers since the R9 290X uses the same GPU architecture, GCN2, as the A8-7600.

I am having almost the same problems. But for me even the "assess performance" in SVP Manager crashes at 66% with:

15:42:22.607 [i]: Performance: motion vectors estimation = 2473
15:42:33.120 [i]: Performance: CPU-based frame rendering = 4052
realloc(): invalid pointer
Neúspěšně ukončen (SIGABRT)

mpv crashes with the aforementioned mesa error (no matter what video output I choose, even with vo=null). I have tried vlc, with the same result, except the Mesa error now appears in SVP log.
From what I've found on the web, it is probably caused by a LLVM version mismatch. What LLVM version are you building SVP with at the moment? I'm currently running SVP 4.5.0.205

LLVM 10.0.1
mesa 20.2.4
vapoursynth 52
mpv 0.33.0
vlc 3.0.11.1
kernel 5.10.5

I have attached clinfo and SVP log. The SVP log first runs mpv, then VLC, then the performance test which crashes it.

While reading through various 4-year old posts in this thread, I can't help but notice that Chainik nowadays seems a bit less...joyful shall we say (at least in this thread he is; I've admittedly kind of taken to ignoring the rest of the "Using SVP" forum now that I'm doing more and more with Linux).

Is this not the issue about SVP running without the tray icon being visible, an issue I had back six years ago with Linux Mint 18.1?:

I'm well aware of that, but the one thing mesa's OpenCL lacks that SVP needs is "image support" (scroll down near the bottom under "OpenCL 1.0"): https://mesamatrix.net/

To clarify, I asked about this around two years ago and Chainlink established to me that the lack of image support was the sticking point:
https://www.svp-team.com/forum/viewtopi … 502#p71502

Therefore one cannot use mesa's OpenCL directly for SVP until the currently-draft image support gets merged or the like.

...Uh, I already said I did in my two lengthy posts above on this very page.  I can get it working on the A8-7600's iGPU pretty easily by simply getting the Ubuntu 20.04 driver that AMD provides for the R9 290X dGPU.

To clarify, ROCm is used for the OpenCL portion of AMD's vendor-supplied Linux graphics driver as of a few years ago.

But the bigger issue is that I was unable to get ROCm OpenCL working on my HD7850 dGPU on Mint 20.1.  While I could get OpenCL working on Mint 19.3, I wasn't able to get SVP working with mpv or vlc (mpv+svp used to "just work" with djcj's now-removed ppa however).

(for reference, the multithreaded CPU grunt of the A8-7600 is considerably slower than the Xeon X3470 that I already own, so my "plan B" was to try and pair that HD7850 with my Xeon)

Do note that SVP and mpv worked fine without GPU acceleration on Mint 20.1.

Wanted to check here before filing a bug report:

OS: Fedora 34
Kernel: 5.13.4-200
SVP: 4.5.0.205

MPV crashes (while using SVP) during any seek operation with libvmaf v2.1.1 & ffmpeg 4.4-4, but works fine with libvmaf v1.5.3 and ffmpeg 4.4-2.
Final error from terminal: Job 1, 'mpv --profile=svp --loop $argv' terminated by signal SIGSEGV (Address boundary error)

I suspect this has more to do with libvmaf than ffmpeg, but included both of their version numbers just in case. I've pinned ffmpeg and libvmaf to the lower version for now.

Anyone else have this problem?
