mpv.net

mpv.net is a libmpv based media player for Windows, it looks and works like mpv, even shares the settings and therefore the mpv documentation applies.

mpv and mpv.net have a learning curve and are only suitable for experienced users.

mpv manual: https://mpv.io/manual/master/

Features

• Customizable context menu defined in the same file as the keybindings
• Addon API for .NET languages
• 5 different scripting languages are supported, Python scripting implemented with IronPython, C# implemented with CS-Script, Lua and JavaScript implemented in libmpv and PowerShell
• mpv's OSC, IPC, conf files and more

Context Menu

The context menu can be customized via input.conf file located at:

C:\Users\Frank\AppData\Roaming\mpv\input.conf

if it's missing mpv.net generates it with the following defaults:

https://github.com/stax76/mpv.net/blob/master/mpv.net/Resources/input.conf.txt

C# Scripting

A simple C# script located at:

C:\Users\Frank\AppData\Roaming\mpv\scripts\test.cs

or

startup\scripts\test.cs

using mpvnet;

class Script
{
    public Script()
    {
        var fs = mpv.GetStringProp("fullscreen");
        mpv.Command("show-text", "fullscreen: " + fs);
        mpv.ObserveBoolProp("fullscreen", FullscreenChange);
    }

    void FullscreenChange(bool val)
    {
        mpv.Command("show-text", "fullscreen: " + val.ToString());
    }
}

Python Scripting

A simple Python script located at:

C:\Users\user\AppData\Roaming\mpv\scripts

or

startup\scripts

# when seeking displays position and
# duration like so: 70:00 / 80:00
# which is different from mpv which
# uses 01:10:00 / 01:20:00

import math

def seek():
    mp.commandv('show-text',
        format(mp.get_property_number("time-pos")) + " / " + format(mp.get_property_number("duration")))

def format(f):
    sec = round(f)
    
    if sec < 0:
        sec = 0
    
    pos_min_floor = math.floor(sec / 60)
    sec_rest = sec - pos_min_floor * 60
    return add_zero(pos_min_floor) + ":" + add_zero(sec_rest)

def add_zero(val):
    val = round(val)
    return "" + str(int(val)) if (val > 9) else "0" + str(int(val))

mp.register_event("seek", seek) # or use: mp.Seek += seek

PowerShell Scripting

A simple PowerShell script located at:

C:\Users\user\AppData\Roaming\mpv\scripts

or

startup\scripts

Please note that PowerShell don't allow assigning to events and mpv.net uses as workaround the script filename.

$position = [mp]::get_property_number("time-pos");
[mp]::commandv("show-text", $position.ToString() + " seconds")
