mpv plugin

plugin for the mpv media player

mpv plugin can remote control mpv media player using the JSON-based IPC protocol to open and play videos, apply video filters, pause video, slow down playback speed and so on

example (open ~/video.mp4 and apply chromahold filter)

#!mpv

loadfile ${HOME}/video.mp4

vf set "chromahold:color=green:blend=0.08"

when this code is evaluated by pressing "CTRL + e" dublang sends it to mpv unix socket file by default located at /tmp/dublang-mpv.sock

to see a list of available commands go to the mpv documentation

• https://mpv.io/manual/master/#command-interface

the ffmpeg documentation can also be useful

• https://ffmpeg.org/ffmpeg-filters.html#Video-Filters

mpv commands synthatic sugar

dublang plugin add synthatic sugar to mpv commands, specially for video filters, including also the ffmpeg filters supported by mpv

example

#!mpv

vf set "chromahold:color=green:blend=0.08"

the same code can also be expressed as

#!mpv

chromh $ col green $ ble 0.08

the function chromh and its arguments represented by $ col green and $ ble 0.08 are translated to vf set "chromahold:color=green:blend=0.08"

this feature is in a very experimental stage and might change in next versions

the list of available functions can be found at mpv plugin source code

• https://codeberg.org/joenio/dublang/src/branch/main/lua/dublang/plugins/mpv.lua

mpv function: video

the Lua global variable config.path.mpv can be used to to tell mpv plugin where is the default path for videos

#!dublang

config.path.mpv = "/home/user/videos"

#!mpv

video "dune/01.mp4"

video command accept an optional argument to change the time position to start the playback as a relative percent number

(example loading a movie on relative time of 50%)

#!mpv

video "dune/01.mp4" 50%

• alert! this requires mpv version 0.38.0 or greather
