Re: SVP 4 Linux

Two things I've noticed over the last day testing it. First of all, secondary instances of mpv sometimes lag really badly, not sure if SVP's fault or not. The second thing is occasionally instances will flash white/background for a frame during playback, this is really inconsistent though and again not sure if it's SVP's fault or something else (like vapoursynth).

Re: SVP 4 Linux

You mean running two mpv instances at the same time?
I'm not sure how they would share the same IPC socket o_O

Yes I suspected it could be a socket issue, however, it's very happy to playback despite that. Perhaps if the socket is in use it just doesn't write one. None but the first instance of mpv are affected by SVP at all it would seem (which is not unexpected and I believe windows behaves the same way). I've come up with a solution of using an alias/script wrapper to launch mpv with the needed arguments for what I REALLY want to run smooth and that way everything else loads as it did pre-SVP as they aren't in the config any more. Multiple instances are pretty common, especially when you use it in conjunction with youtube-dl etc.

I really, really wish stuff appended to mpv's playlist better (at all?) but it is what it is...

Re: SVP 4 Linux

maybe SMPlayer can handle playlists better than plain mpv...

it's possible to add some logic to SVP Manager to launch every other mpv instance with a unique socket name, but not right now
after all it can handle multiple ffdshow instances at the same time in Windows

Maybe, I just find it really ugly so I'll deal with instances.

This would be really cool actually but something I totally understand as not a priority, maybe one day in the future.

Re: SVP 4 Linux

EDIT 2: Okay I found the real fix, I had to unplug my HDMI cable from my GPU and plug it back in every boot to get SVP to work... Maybe a daemon is not being started on boot... Hmm...

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

EDIT: Solved. But I am unsure what fixed it. Here are the things I tried:

1) disable iGPU intel graphics in bios
2) installed libmediainfo (mediainfo was installed)
3) ran "mediainfo" once in terminal
4) reinstalled qt-svg
5) installed hicolor-icon-theme
6) changed desktop theme to GTK+ and back to Fusion
7) updated kernel and gtk and rebooted

Likely the kernel update fixed it, so it was likely Linux-Zen kernel.

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

I need some help on running the SVP installer on an ArchLinux, Linux-Zen, XFCE machine.

Currently running the installer from terminal gives this direct error (running directly does nothing but produce a .lock file):

Re: SVP 4 Linux

Hi SVP devs,

I was trying out SVPFlow in realtime using Vapoursynth and mpv on Arch Linux, but can't get it working at all.

I changed the sample script as follows

import vapoursynth as vs

core = vs.get_core(threads=36)

clip = video_in
clip = clip.resize.Bicubic(format=vs.YUV420P8)

super_params="{gpu:1}"
analyse_params="{}"
smoothfps_params="{rate:{num:5,den:2}}"

super  = core.svp1.Super(clip,super_params)
vectors= core.svp1.Analyse(super["clip"],super["data"],clip,analyse_params)
smooth = core.svp2.SmoothFps(clip,super["clip"],super["data"],vectors["clip"],vectors["data"],smoothfps_params)
smooth = core.std.AssumeFPS(smooth,fpsnum=smooth.fps_num,fpsden=smooth.fps_den)

smooth.set_output()

but I got the following errors

[vapoursynth] Script evaluation failed:

Re: SVP 4 Linux

Am running SVP under Arch linux, Nvidia GTX 970 with proprietary drivers.

[CBM]_Cowboy_Bebop_-_Session_06_-_Sympathy_for_the_Devil_[720p]_[EC168C9C].mkv   
I get audio desync on this file, and only this file so far. No matter whether I use mpv or smplayer, or disable frame rate conversion, as long as SVP is integrated to the player the audio immediately starts desyncing(slower than video), fixable by peeking and then it immediately starts desyncing again.

File is available from here https://kat.cr/cbm-cowboy-bebop-1-26-co … 98131.html

Re: SVP 4 Linux

> No matter whether I use mpv or smplayer, or disable frame rate conversion, as long as SVP is integrated to the player the audio immediately starts desyncing

I think I know the reason - it's a inconsistency between the actual video frame rate and the value written in the container and thus used as a base frame rate for the frc conversion.
This value is exposed by mpv to the Vapoursynth engine as a global variable called "container_fps". If the real fps doesn't match - we're probably screwed o_O

You need to add keyword fps when calling core.svp2.SmoothFps to be fps=container_fps

smooth = core.svp2.SmoothFps(clip,super["clip"],super["data"],vectors["clip"],vectors["data"],smoothfps_params, fps=container_fps)

You don't need to add optional keyword fps to invoke SmoothFps if the clip is called with core.ffms2.Source
This is the thread that I asked about it before for reference

I think the default already container_fps though.

Re: SVP 4 Linux

I am running Mint 17.03 with the 364.21 drivers and have great playback with MPV
that is tear free. My concern is paying for a pro license to see if this works. I have
no problem paying for all the features if I can make it work on my HTPC. I know enough
to basic commands. Is there a test version I can try to see if I can make it work?
Or is it best to wait till it is all sorted out?

Thanks Greg

Perhaps you could ask devs via email about paying for it and then refund if ask in X hours. But this depends solely on them if they agree or not.

The only thing keeping me from using linux is there is no 1080p 71.928 for crt to push out raster ringing
on the projector. I prefer it over Windows pq wise.

Is there a way to enable this resolution in Linux? And all the timings that works so well with windows.

Hi. i have a problem Ubuntu 16.04. i installed SVP normally but i want to activate it, i got this error "Registration: server error 6 - SSL handshake failed"

How can i solve this prob?

Re: SVP 4 Linux

The new 4.0.0.80 build is out introducing VLC support and other improvements.

Now it's free and doesn't require neither license key nor activation!

the Manager doesn't have write access to the config dir for some reason
which is usually somewhere near ~/.local/SVP 4

nope

yeah, and this one was on the server side... fixed now big_smile

Re: SVP 4 Linux

Arch Linux, up to date system.  All required dependencies met, plus proprietary video and OpenCL as well as VLC. 

My issue is twofold:

One: VLC is not being detected as an active playback source.  Reinstalling VLC nor SVP doesn't make a difference.  Not sure where to go with this.

Two: RESOLVED.  I figured I'd include this anyways since I already typed it up and in case anyone else is having issues as well.  Reinstalling the package opencl-nvidia and then restarting my system completely fixed the following paragraph's issue.

My GPU (NVIDIA MSI 780 Ti with proprietary drivers and OpenCL) is not detected as a rendering device.  I'm thinking this is related to how Steam is unable to check for updates as well, though it does recognize my system correctly when the hardware survey comes around.  Might be an issue related to the fact that I have both 32 and 64 bit drivers installed, as Steam on Linux is pretty stupid like that.  I also noticed that SVP doesn't notice that I have OpenCL installed. 

I can post whatever is relevant.  All I see so far is the following.
