Celluloid (formerly GNOME MPV) is a simple GTK+ frontend for mpv. Celluloid interacts with mpv via the client API exported by libmpv, allowing access to mpv's powerful playback capabilities.

Packaging status

Ubuntu users can use this PPA to get more up-to-date versions of Celluloid.


Flatpak packages support multiple distributions and are sandboxed. Flatpak 0.9.5+ is recommended for best integration.

Stable releases are hosted on Flathub:

Opening files

There are 4 ways to open files in Celluloid.

  1. Passing files and/or URIs as command line arguments.
  2. Using the file chooser dialog box, accessible via the "Open" menu item.
  3. Typing URI into the "Open Location" dialog box, accessible via the menu item with the same name.
  4. Dragging and dropping files or URIs onto Celluloid.

Manipulating playlist

The playlist is hidden by default. To show the playlist, click the "Playlist" menu item or press F9. Files can be added by dragging and dropping files or URIs onto the playlist. Dropping files or URIs onto the video area will replace the content of the playlist. Playlist files or online playlists (eg. YouTube's playlist) will be automatically expanded into individual items when loaded.

Items in the playlist can be reordered via drag-and-drop. To remove items from the playlist, select the item by clicking on it then press the delete button on your keyboard.


Celluloid can be configured using the preferences dialog accessible via the "Preferences" menu item. Additional configuration options can be set from an external file using the same syntax as mpv's mpv.conf. See mpv's manual for the full list of options. The file must be specified and enabled in the preferences dialog under the "MPV Configuration" section.

It is also possible to set mpv options by putting the options — as you would pass to mpv on the command line — in Extra MPV Options text box in the preferences dialog. You can also pass options directly on the command line by adding mpv- prefix to the option name. For example, using the option --mpv-vf=flip when launching Celluloid is equivalent to using --vf=flip in mpv.

User Scripts

Celluloid can use most mpv user scripts as-is. Some user scripts may define keybindings that conflict with Celluloid, in which case you'll need to resolve the conflict by explicitly defining new keybindings using input.conf. See mpv's manual for more details.

User scripts can be installed by switching to the "Plugins" tab in the preferences dialog and dropping the files there. A list of mpv user scripts can be found here.


Celluloid defines a set of keybindings in the macro DEFAULT_KEYBINDS, which can be found in src/celluloid-def.h. The syntax used is exactly the same as mpv's input.conf. These keybindings are applied on top of default keybindings provided by mpv.

Additional keybindings can be defined in an external file using mpv's input.conf syntax. The file can be set in the preferences dialog under the "Keybindings" section.
