What is mpv-launcher.exe?
mpv-launcher.exe is a lightweight graphical launcher for the MPV media player. It provides a minimal user interface to open videos and audio files, supports drag-and-drop, and exposes common playback options (subtitles, audio track, volume presets) so you can start MPV with preferred settings without typing long commands.
mpv-launcher builds command-line options from user selections and launches mpv.exe, acting as a thin wrapper around MPV's capabilities. It does not decode media itself, but configures options and file paths to streamline playback.
Quick Fact: mpv-launcher originated to simplify MPV usage and remains a lightweight frontend for power users.
Types of MPV Processes
- Launcher Process: The mpv-launcher GUI that assembles playback options and launches MPV
- MPV Client Process: mpv.exe instance handling playback for a session
- Subtitle Processor: MPV loads and parses subtitle files when selected
- Audio Track Handler: MPV selects the active audio track for the session
- Video Decoder: MPV uses libavcodec for decoding the media
- Background Helper: Optional background tasks like thumbnail caching
Is mpv-launcher Safe?
Yes, mpv-launcher.exe is safe when obtained from official MPV project repositories or trusted distributors.
Is mpv-launcher.exe a Virus or Malware?
The legitimate mpv-launcher.exe is not a virus. Malware may imitate names. Verify digital signature and file location.
How to Tell if mpv-launcher.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\mpv-launcher\ or C:\Program Files (x86)\mpv-launcher\. Any mpv-launcher.exe elsewhere is suspicious.
- Digital Signature:: Right-click the executable in Explorer or Task Manager → Properties → Digital Signatures. Should show the "MPV Project" signer.
- Resource Usage:: Normal usage is 0-8% CPU and 20-150 MB memory. Extremely high usage when idle is suspicious.
- Behavior:: Launcher should launch MPV only when you open media. Extra hidden network activity or auto-start without user action is a red flag.
Red Flags: If mpv-launcher.exe is located in unusual folders (like Temp or AppData), runs on startup without user action, has no valid signature, or shows unexpected network activity, scan with antivirus immediately.
Why Is mpv-launcher.exe Running on My PC?
mpv-launcher.exe runs when you initiate playback with MPV via the launcher or when a configuration preset is loaded. It may also run briefly to register file associations or to load plugins.
Reasons it's running:
- Active Playback Initiation: You clicked a media file or playlist routed through mpv-launcher, which starts an mpv.exe session.
- Background Sessions: MPV sessions can be started in background when a script or launcher preset is configured.
- Startup or Auto-Launch: MPV-launcher may be configured to start with Windows or when a media file is opened from a file manager.
- File Associations: Launcher registers associations so double-clicking media files opens MPV through the launcher.
- Playlist or Batch Actions: A batch script or launcher preset may launch multiple MPV instances for a playlist or multiple files.
Can I Disable or Remove mpv-launcher?
Yes, you can disable mpv-launcher. It's safe to close the launcher when not in use, and you can uninstall it completely if you prefer a different MPV workflow.
