SVP:mpv

Setting up mpv

(developer's web site)

mpv must be built with Vapoursynth support.

Installation - Windows

Install the following packages via SVP's "Additional programs and features":

• [VPS_64] mpv video player and/or
• [VPS_64] mpv shared library

You can also use builds by shinchiro, but SVP's builds may have some tweaks missing in the 'official' mpv necessary in some cases.

Installation - Linux

See building instructions

Installation - macOS

Install mpv from Homebrew

Compiling mpv from sources

To use Vapoursynth filters you have to install the Vapoursynth package and build mpv 0.17.0 or later with the --enable-vapoursynth build flag.

Basic settings

The only necessary mpv option is (Linux and macOS)

input-ipc-server=/tmp/mpvsocket

or (Windows)

input-ipc-server=mpvpipe

You can put this line into mpv.conf (usually located in ~/.config/mpv on OS X and Linux and in %APPDATA%\mpv on Windows)

input-ipc-server=/tmp/mpvsocket
# or
input-ipc-server=mpvpipe

Since SVP >= 4.3.191 (2020-04-11) you can use the mpvSockets LUA script instead of fixed 'input-ipc-server'. This will also allow to use SVP in more than one mpv windows simultaneously.

Only "copy-back" hardware video decoders are compatible with Vapoursynth filters, use

hwdec=auto-copy
hwdec-codecs=all

This one fixes audio desync

hr-seek-framedrop=no

"Watch later" feature is not compatible with SVP, set

no-resume-playback

More useful options:

# Can fix stuttering in some cases, in other cases probably causes it. Try it if you experience stuttering on macOS.
opengl-early-flush=no

Since mpv has tons of options it's recommended to use SMPlayer instead of plain mpv (sadly NOT for OS X users).

Advanced features

• autospeedwin - the script to adjust monitor refresh rate to match video speed
• autospeed - the same script for Linux
• mpvSockets - creates one IPC sockets per mpv instance, instead of one socket for the last started instance
