A request for SmoothVideo Project

[colin_b]

I was digging around a few minutes ago when I came across SmoothVideo Project (SVP). I used to use it on Windows, and I'm delighted to see there's now a free Linux version.

A brief explanation of the function of SmoothVideo Project (SVP):

https://blog.programster.org/smooth-vid ... k-with-svp

SVP is a program that allows you to watch a video on your computer and use frame interpolation to create smoother playback at whatever framerate you desire. I found that greatly improved movies by playing them back at 30fps on my 60hz monitor so that it felt "cinematic" whilst keeping linear motion, such as when the camera pans to the side, smooth rather than jagged. It is also great for playing back all other content, such as music videos, at 60fps.

Compatible video players

mpv itself can act as a standalone video player
SMPlayer - a recommended UI
Plex Media Player
VLC

Prerequisites

Qt 5.5.0 or later
Vapoursynth R31 or later
MediaInfo
lsof command line tool (install it via your package manager)
Required for SVPtube: Python 3.5
(recommended) Proprietary video drivers including OpenCL ICD
(recommended) mpv 0.17 or later built with Vapoursynth support
(optional) Recommended UI for mpv: SMPLayer
(optional) VLC 2.1 or later

Would it be possible to add SVP to the repo?

If it works correctly it could be be a boon for videophiles.

It's freeware, but proprietary, so I don't think we can add it, though I haven't looked at the redistribution license. I did rebuild MPV in our test repo with vapoursynth support, install and set up SVP, and it does work for playing at 60 fps. The newer mpv is on its way to the test repo.

I have to research how to get SMPlayer and VLC to use SVP, though.

[Stevo]

It also "just works" with mpc-qt from the test repo if you have the new mpv and have svp4 running. I couldn't get Gnome-MPV, VLC, or SMPlayer to use it, though.

A belated thanks for the info.

It's a pity it only works with mpc-qt. I tried that about a month ago, but I had problems with it, so I got rid of it. SMPlayer works for me, but since it doesn't seem to work with SVP I'll have to live without smooth video.

[Stevo]

What do you mean? Did you upgrade mpv from the test repo per the instructions? I also found that I can just right-click a video, choose "open with" "SVP 4 Linux", and it and mpv start up and play the video. MPC-Qt uses the newer libmpv1, so can also use SVP 4.

[colin_b]

Oops, I didn't realize mpv was on the OK list.

I downloaded svp4, extracted it, opened the setup wizard and left the default setting for where it should be installed (/home/Colin/SVP 4).

During installation I got the following error:

I scratched my head and decided to uninstall & reinstall mpv from the test repo to see if this would solve the problem.

Unfortunately the same problem occurred.

Are you running 64-bit?

[colin_b]

Yes. Here's my system info:

That's weird. So, how did you execute the .run file?

[colin_b]

That's weird.

I had a dig around and found this forum thread talking about the error.

https://www.svp-team.com/forum/viewtopic.php?id=4165

I run the installer from terminal and catch this:

Code: Select all

lazyc97@lazyc97-Inspiron-7559:~/Downloads$ sudo ./svp4-linux-64.run
[49] Warning: A style sheet file is specified, but it does not exist.
[12876] Warning: /home/lazyc97/SVP 4/SVPManager: error while loading shared libraries: libmediainfo.so.0: cannot open shared object file: No such file or directory

...

Nevermind, I solved it by

Code: Select all

sudo apt install qt5-default mediainfo

I checked the installation requirements.

https://www.svp-team.com/wiki/Manual:Installation

Qt 5.5 or later;
Vapoursynth;
Mediainfo;
Python 3.5;
Proprietary video drivers with OpenCL ICD (AMD, NVIDIA), or Beignet for Intel;
mpv compiled with support of Vapoursynth script engine;
lsof.

I checked the MXPI and found I didn't have Vapoursynth or Mediainfo installed, so install them I did.

The SVP install then worked, but then I couldn't get video output from mpv.

After some fruitless messing around I threw in the towel. I opened up Timeshift and reverted my OS to its state before install. For some reason this didn't get rid of SVP, but mpv has started working again. I'm baffled as to how SVP has stayed on my system.

I rescind my request for SVP.
