Package: plex-mpv-shim
MPV Shim for PlexMPV Shim is a simple and lightweight Plex client, with support for Windows
and Linux. Think of it as an open source Chromecast for Plex. You can cast almost
anything from Plex and it will Direct Play. Subtitles are fully supported, and
there are tools to manage them like no other Plex client.Getting StartedIf you are on Windows, simplydownload the binary.
If you are using Linux or OSX, please see theLinux InstallationorOSX Installationsections below.To use the client, simply launch it and cast your media from another Plex application.
The mobile and web applications are supported. You do not have to log in to the client
or set it up in any other way.If you want to use the web application to cast, you must either be on the same network as
a Plex server (an empty one will work) or install theMPV Shim Local Connectionuser script.The application runs with a notification icon by default. You can use this to view the application log, open the config folder, and open the application menu.Advanced FeaturesMenuTo open the menu, presscon your computer orhomewithin the Plex mobile apps.The menu enables you to:Adjust video transcoding quality.Change the default transcoder settings.Change subtitles or audio, while knowing the track names.Change subtitles or audio for an entire series at once.Mark the media as unwatched and quit.Configure shader packs and SVP profiles.On your computer, use the arrow keys, enter, and escape to navigate. On your phone, use
the arrow buttons, ok, back, and home to navigate. (The option for remote controls is
shown next to the name of the client when you select it from the cast menu.)Please also note that the on-screen controller for MPV (if available) cannot change the
audio and subtitle track configurations for transcoded media. It also cannot load external
subtitles. You must either use the menu or the application you casted from.Shader PacksShader packs are a recent feature addition that allows you to easily use advanced video
shaders and video quality settings. These usually require a lot of configuration to use,
but MPV Shim's default shader pack comes withFSRCNNXandAnime4Kpreconfigured. Try experimenting with video
profiles! It may greatly improve your experience.Shader Packs are ready to use as of the most recent MPV Shim version. To use, simply
navigate to theVideo Playback Profilesoption and select a profile.For details on the shader settings, please seedefault-shader-pack.
If you would like to customize the shader pack, there are details in the configuration section.SVP IntegrationSVP integration allows you to easily configure SVP support, change profiles, and enable/disable
SVP without having to exit the player. It is not enabled by default, please see the configuration
instructions for instructions on how to enable it.Keyboard ShortcutsThis program supports most of thekeyboard shortcuts from MPV. The custom keyboard shortcuts are:< > to skip episodesq to close playerw to mark watched and skipu to mark unwatched and quitc to open the menuHere are the notable MPV keyboard shortcuts:space - Pause/Playleft/right - Seek by 5 secondsup/down - Seek by 1 minutes - Take a screenshotS - Take a screenshot without subtitlesf - Toggle fullscreen,/. - Seek by individual frames[/] - Change video speed by 10%{/} - Change video speed by 50%backspace - Reset speedm - Muted - Enable/disable deinterlaceCtrl+Shift+Left/Right - Adjust subtitle delay.ConfigurationThe configuration file is located in different places depending on your platform. You can open the
configuration folder using the systray icon. When you launch the program on Linux or OSX from the terminal,
the location of the config file will be printed. The locations are:Windows -%appdata%\plex-mpv-shim\conf.jsonLinux -~/.config/plex-mpv-shim/conf.jsonMac OSX -Library/Application Support/plex-mpv-shim/conf.jsonCygWin -~/.config/plex-mpv-shim/conf.jsonYou can specify a custom configuration folder with the--configoption.TranscodingYou can adjust the basic transcoder settings via the menu.always_transcode- This will tell the client to always transcode, without asking. Default:falseThis may be useful if you are using limited hardware that cannot handle advanced codecs.You may have some luck changingclient_profilein the configuration to a more restrictive one.auto_transcode- This will ask the server to determine if transcoding is suggested. Default:truetranscode_kbps- Transcode bandwidth to request. Default:2000direct_limit- Also limit direct play totranscode_kbps. Default:falseNote thatdirect_limitcannot be overriden without changingtranscode_kbps.Ifdirect_limitis not set, the player assumes the server will set the limit.adaptive_transcode- Tell the server to adjust the quality while streaming. Default:falseShell Command TriggersYou can execute shell commands on media state using the config file:media_ended_cmd- When all media has played.pre_media_cmd- Before the player displays. (Will wait for finish.)stop_cmd- After stopping the player.idle_cmd- After no activity foridle_cmd_delayseconds.Subtitle Visual SettingsAll of these settings apply to direct play and are adjustable through the controlling app. Note that some may not work depending on the subtitle codec. Subtitle position and color are not available for transcodes.subtitle_size- The size of the subtitles, in percent. Default:100subtitle_color- The color of the subtitles, in hex. Default:#FFFFFFFFsubtitle_position- The position (top, bottom, middle). Default:bottomExternal MPVThe client now supports using an external copy of MPV, including one that is running prior to starting
the client. This may be useful if your distribution only provides MPV as a binary executable (instead
of as a shared library), or to connect to MPV-based GUI players. Please note that SMPlayer exhibits
strange behaviour when controlled in this manner. External MPV is currently the only working backend
for media playback on OSX.mpv_ext- Enable usage of the external player by default. Default:falseThe external player may still be used by default iflibmpv1is not available.mpv_ext_path- The path to thempvbinary to use. By default it uses the one in the PATH. Default:nullIf you are using Windows, make sure to use two backslashes. Example:C:\\path\\to\\mpv.exempv_ext_ipc- The path to the socket to control MPV. Default:nullIf unset, the socket is a randomly selected temp file.On Windows, this is just a name for the socket, not a path like on Linux.mpv_ext_start- Start a managed copy of MPV with the client. Default:trueIf not specified, the user must start MPV prior to launching the client.MPV must be launched with--input-ipc-server=[value of mpv_ext_ipc].mpv_ext_no_ovr- Disable built-in mpv configuration files and use user defaults.Please note that some scripts and settings, such as ones to keep MPV open, may break
functionality in MPV Shim.Keyboard ShortcutsYou can reconfigure the custom keyboard shortcuts. You can also set them tonullto disable the shortcut. Please note that disabling keyboard shortcuts may make some features unusable. Additionally, if you remapq, using the default shortcut will crash the player.kb_stop- Stop playback and close MPV. (Default:q)kb_prev- Go to the previous video. (Default:<)kb_next- Go to the next video. (Default:>)kb_watched- Mark the video as watched and skip. (Default:w)kb_unwatched- Mark the video as unwatched and quit. (Default:u)kb_menu- Open the configuration menu. (Default:c)kb_menu_esc- Leave the menu. Exits fullscreen otherwise. (Default:esc)kb_menu_ok- "ok" for menu. (Default:enter)kb_menu_left- "left" for menu. Seeks otherwise. (Default:left)kb_menu_right- "right" for menu. Seeks otherwise. (Default:right)kb_menu_up- "up" for menu. Seeks otherwise. (Default:up)kb_menu_down- "down" for menu. Seeks otherwise. (Default:down)kb_pause- Pause. Also "ok" for menu. (Default:space)kb_debug- Triggerpdbdebugger. (Default:~)seek_up- Time to seek for "up" key. (Default:60)seek_down- Time to seek for "down" key. (Default:-60)seek_right- Time to seek for "right" key. (Default:5)seek_left- Time to seek for "left" key. (Default:-5)Shader PacksShader packs allow you to import MPV config and shader presets into MPV Shim and easily switch
between them at runtime through the built-in menu. This enables easy usage and switching of
advanced MPV video playback options, such as video upscaling, while being easy to use.If you select one of the presets from the shader pack, it will override some MPV configurations
and any shaders manually specified inmpv.conf. If you would like to customize the shader pack,
useshader_pack_custom.shader_pack_enable- Enable shader pack. (Default:true)shader_pack_custom- Enable to use a custom shader pack. (Default:false)If you enable this, it will copy the default shader pack to theshader_packconfig folder.This initial copy will only happen if theshader_packfolder didn't exist.This shader pack will then be used instead of the built-in one from then on.shader_pack_remember- Automatically remember the last used shader profile. (Default:true)shader_pack_profile- The default profile to use. (Default:null)If you useshader_pack_remember, this will be updated when you set a profile through the UI.shader_pack_subtype- The profile group to use. The default pack containslqandhqgroups. Usehqif you have a fancy graphics card.SVP IntegrationTo enable SVP integration, setsvp_enabletotrueand enable "External control via HTTP" within SVP
under Settings > Control options. Adjust thesvp_urlandsvp_socketsettings if needed.svp_enable- Enable SVP integration. (Default:false)svp_url- URL for SVP web API. (Default:http://127.0.0.1:9901/)svp_socket- Custom MPV socket to use for SVP.Default on Windows:mpvpipeDefault on other platforms:/tmp/mpvsocketCurrently on Windows the built-in MPV does not work with SVP. You must download MPV yourself.Download the latest MPV buildfrom here.Follow thevapoursynth instructions.Make sure to use the latest Python, not Python 3.7.In the config file, setmpv_exttotrueandmpv_ext_pathto the path tompv.exe.Make sure to use two backslashes per each backslash in the path.Other Configuration Optionsplayer_name- The name of the player that appears in the cast menu. Initially set from your hostname.http_port- The TCP port to listen on for Plex to control the player. Default:3000enable_play_queue- Enable play queue support. Default:trueIf you disable this, the application will queue media based on the series.This is a legacy feature. It is not regularly tested.client_uuid- The identifier for the client. Set to a random value on first run.audio_ac3passthrough- Does not work. Currently only changes transcoder settings. Default:falseaudio_dtspassthrough- Does not work. Currently only changes transcoder settings. Default:falseallow_http- Allow insecure Plex server connections. Default:falseThis may be useful if you are using a Plex server offline or not signed in.client_profile- The client profile for transcoding. Default:Plex Home TheaterIt may be useful to change this on limited hardware.If you change this, it should be changed to a profile that supportshlsstreaming.sanitize_output- Prevent Plex tokens from being printed to the console. Default:truefullscreen- Fullscreen the player when starting playback. Default:trueenable_gui- Enable the system tray icon and GUI features. Default:truemedia_key_seek- Use the media next/prev keys to seek instead of skip episodes. Default:falseenable_osc- Enable the MPV on-screen controller. Default:trueIt may be useful to disable this if you are using an external player that already provides a user interface.log_decisions- Log the full playback URLs. Default:falsempv_log_level- Log level to use for mpv. Default:infoOptions: fatal, error, warn, info, v, debug, traceidle_when_paused- Consider the player idle when paused. Default:falsestop_idle- Stop the player when idle. (Requiresidle_when_paused.) Default:falseskip_intro_always- Always skip intros, without asking. Default:falseskip_intro_prompt- Prompt to skip intro via seeking. Default:truemenu_mouse- Enable mouse support in the menu. Default:trueThis requires MPV to be compiled with lua support.MPV ConfigurationYou can configure mpv directly using thempv.confandinput.conffiles. (It is in the same folder asconf.json.)
This may be useful for customizing video upscaling, keyboard shortcuts, or controlling the application
via the mpv IPC server.Tips and TricksVarious tips have been found that allow the media player to support special
functionality, albeit with more configuration required.Open on Specific MonitorPlease note: Edits to thempv.confwill not take effect until you restart the application. You can open the config directory by using the menu option in the system tray icon.Option 1: Select fullscreen output screen through MPV.
Determine which screen you would like MPV to show up on.If you are on Windows, right click the desktop and select "Display Settings". Take the monitor number and subtract one.If you are on Linux, runxrandr. The screen number is the number you want. If there is only one proceed toOption 2.Add the following to yourmpv.confin theconfig directory, replacing0with the number from the previous step:fs=yes
fs-screen=0Option 2: (Linux Only) If option 1 does not work, both of your monitors are likely configured as a single "screen".Runxrandr. It should look something like this:Screen 0: minimum 8 x 8, current 3520 x 1080, maximum 16384 x 16384

Make sure to change the port that the player uses.Audio PassthroughYou can editmpv.confto support audio passthrough. Auser on Reddithad luck with this config:audio-spdif=ac3,dts,eac3 # (to use the passthrough to receiver over hdmi)
audio-channels=2 # (not sure this is necessary, but i keep it in because it works)
af=scaletempo,lavcac3enc=yes:640:3 # (for aac 5.1 tracks to the receiver)MPV Crashes with "The sub-scale option must be a floating point number or a ratio"Run the plex-mpv-shim program with LC_NUMERIC=C.Use with gnome-mpv/celluloidYou can usegnome-mpvwith MPV Shim, but you must launchgnome-mpvseparately before MPV Shim. (gnome-mpvdoesn't support the MPV command options directly.)Configure MPV Shim with the following options (leave the other ones):{"mpv_ext":true,"mpv_ext_ipc":"/tmp/gmpv-socket","mpv_ext_path":null,"mpv_ext_start":false,"enable_osc":false}Then withingnome-mpv, click the application icon (top left) > Preferences. Configure the following Extra MPV Options:--idle --input-ipc-server=/tmp/gmpv-socketHeavy Memory UsageA problem has been identified where MPV can use a ton of RAM after media has been played,
and this RAM is not always freed when the player goes into idle mode. Some users have
found that using external MPV lessens the memory leak. To enable external MPV on Windows:Download a copy of MPVUnzip it with 7zip.Configurempv_exttotrue. (See the config section.)Configurempv_ext_pathtoC:\\replace\\with\\path\\to\\mpv.exe. (Note usage of two\\.)Run the program and wait. (You'll probably have to use it for a while.)Let me know if the high memory usage is withmpv.exeor the shim itself.On Linux, the process is similar, except that you don't need to set thempv_ext_pathvariable.
On OSX, external MPV is already the default and is the only supported player mode.In the long term, I may look into a method of terminating MPV when not in use. This will require
a lot of changes to the software.DevelopmentIf you'd like to run the application without installing it, run./run.py.
The project is written entirely in Python 3. There are no closed-source
components in this project. It is fully hackable.The project is dependent onpython-mpv,python-mpv-jsonipc, andrequests. If you are using Windows
and would like mpv to be maximize properly,pywin32is also needed. The GUI component
usespystrayandtkinter, but there is a fallback cli mode.If you are using a local firewall, you'll want to allow inbound connections on
TCP 3000 and UDP 32410, 32412, 32413, and 32414. The TCP port is for the web
server the client uses to recieve commands. The UDP ports are for theGDM
discovery protocol.This project is based onhttps://github.com/wnielson/omplex, which
is available under the terms of the MIT License. The project was ported
to python3, modified to use mpv as the player, and updated to allow all
features of the remote control api for video playback. The shaders included
in the shader pack are also available under verious open source licenses,which you can read about here.Linux InstallationIf you are on Linux, you can install via pip.
