SVP 4 Linux (Page 17 of 17)

Please direct me to the write resource:
Following the Vapoursynth build instructions from the wiki, https://www.svp-team.com/wiki/SVP:Linux … om_sources, command "sudo ldconfig" does not come up with expected shell output. I'm getting

/sbin/ldconfig.real: /usr/lib/wsl/lib/libcuda.so.1 is not a symbolic link

However, I can run "vspipe."

There doesn't seem to be mention if these missing symbolic links are going to be a problem in the Vapoursynth or SVP posts. Should I continue to solve this issue? Should I continue asking here or on the Vapoursynth forum?

Hello, does anyone have experience in getting SVP to work in Steam deck?. I've installed VLC via the discover app and installed the VLC support from the installer but it doesn't appear that it working.

Any chance for new features or updates for linux users? Latest ver is still 4.5.0.210. RIFE would be a nice tool to mess around with.

Sorry, I forgot an important part. You need to configure MPV, so it knows where to get SVP's work.

With your file explorer, you can create mpv.conf file in ~/.var/app/io.mpv.Mpv/config/mpv and save this inside of it:

profile=svp
hwdec=auto-copy
hwdec-codecs=all

[svp]
input-ipc-server=/tmp/mpvsocket     # Receives input from SVP
hr-seek-framedrop=no                # Fixes audio desync
resume-playback=no                  # Not compatible with SVP

# Can fix stuttering in some cases, in other cases probably causes it. Try it if you experience stuttering.
#opengl-early-flush=yes

Or alternatively just run this in the terminal, this does it for you:

echo 'profile=svp
hwdec=auto-copy
hwdec-codecs=all

[svp]
input-ipc-server=/tmp/mpvsocket     # Receives input from SVP
hr-seek-framedrop=no                # Fixes audio desync
resume-playback=no                  # Not compatible with SVP

# Can fix stuttering in some cases, in other cases probably causes it. Try it if you experience stuttering.
#opengl-early-flush=yes' > ~/.var/app/io.mpv.Mpv/config/mpv/mpv.conf

That should make it work. Open the video normally through a file explorer while SVP is running.

Note: This part is related to HW decoding, not SVP, if it gives you issues, remove it:

hwdec=auto-copy
hwdec-codecs=all

@InnKeepNY i just tried to build on Ubuntu 22.04 and incurred similar error as you;

what idid is the following:

1. changed the content inside of "mpv-build/mpv/meson_options" to

2. re-run "./rebuild -j4"
   at this point, the error would persist, eg. meson: error: unrecognized arguments: ....

3. would delete the whole "mpv-build" directory and re-download it via command

4. this time would change the echo-arguments, and pass not entirely those from page 1 of the linux guide, but instead

echo --enable-libx264 >> ffmpeg_options
echo --enable-vaapi >> ffmpeg_options
echo -Dvapoursynth=enabled >> mpv_options
echo -Dlibmpv=true >> mpv_options
echo --enable-nvdec >> ffmpeg_options

5. ./rebuild -j4
now it would finish the compile, as desired.

good luck with Debian 12!

So everything seemed to compile fine and everything works great except when Nvidia Optical Flow is engaged the following error pops up:
(on a side note I was able to compile with all of the flags I originally wanted to use. Not sure what changed, I don't THINK I did anything different.)

@kapqa No worries. For me personally I prefer not to use Nvidia Flow anyway - some scenes just do not look right. Its for completeness of the project basically.
So in regards to Deb multimedia you have to make a choice of whether pr not you want/need wine. If deb multimedia is used, the files from there change the C libraries and wine needs them clean in order to function. By "rolling your own" you miss this issue.

Got rid of error with

--vf=format=fmt=yuv420p

mpv option, but still, no interpolation

UPD: Actually, after putting the option to config file it worked.
Still can't get 144 fps on linux, but it's another problem)

@InnKeepNY
dont know if you have solved your problem already, but i had to install this package manually since else it would complain of "Error: nvdec not found ...." or similar.

what i did was to:

1. sudo apt install pkgconf
2. To compile the FFmpeg NVIDIA headers ("ffnvcodec"):

git clone https://git.videolan.org/git/ffmpeg/nv- … eaders.git
cd nv-codec-headers
make
sudo make install

maybe your error can be related to this, maybe can help someone too.
cheers

Sir I wanna thank you! this worked. finally get to watch on 60 fps on the bed. cheers

Switched to MX Linux (debian based) the other week and it's been surprisingly easy getting SVP to work. Biggest problems were getting CUDA support installed and figuring out what 'caused weird instability, but turns out that was the "black bars" stuff, in particular "alter video frame size" option. With all that disabled it runs like a dream and I have GPU acceleration. 
I was surprised that my Windows license wasn't needed for linux. But glad I've supported in some small way either way. 
Oh, one thing that might be better regarding the installer, wouldn't it be better if its default/suggested path was /opt/SVP 4 instead of ~/SVP 4? Personally I hate clutter in my home folder.
