# Clapper
A GNOME media player build using [GJS](https://gitlab.gnome.org/GNOME/gjs) with [GTK4](https://www.gtk.org) toolkit. The media player is using [GStreamer](https://gstreamer.freedesktop.org/) as a media backend and renders everything via [OpenGL](https://www.opengl.org).

### WORK IN PROGRESS
This is still early WIP. Many features are not implemented yet and quite a few are still unstable.

### Features:
* [Hardware acceleration](https://github.com/Rafostar/clapper/wiki/Hardware-acceleration)
* [Floating mode](https://github.com/Rafostar/clapper/wiki/Floating-mode)
* [Adaptive UI](https://raw.githubusercontent.com/Rafostar/clapper/master/media/screencast-mobile-ui.webm)
* [Playlist from file](https://github.com/Rafostar/clapper/wiki/Playlists)
* Chapters on progress bar

## Installation from Flatpak
The `Flatpak` package includes all required dependencies and codecs.
Additionally it also has a few patches, thus some functionalities work better (or are only available) in `Flatpak` version (until my changes are accepted upstream). List of patches used in this version can be found [here](https://github.com/Rafostar/clapper/issues/35).

```sh
flatpak install https://rafostar.github.io/flatpak/com.github.rafostar.Clapper.flatpakref
```

## Packages
The [pkgs folder](https://github.com/Rafostar/clapper/tree/master/pkgs) in this repository contains build scripts for various package formats. You can use them to build package yourself or download one of pre-built packages:

#### Debian, Fedora & openSUSE
Pre-built packages are available in [my repo](https://software.opensuse.org//download.html?project=home%3ARafostar&package=clapper) ([see status](https://build.opensuse.org/package/show/home:Rafostar/clapper))

#### Arch Linux
You can get Clapper from the AUR: [clapper-git](https://aur.archlinux.org/packages/clapper-git)

## Installation from source code
```sh
meson builddir --prefix=/usr/local
sudo meson install -C builddir
```

## Q&A
**Q:** Does using `GJS` negatively impact video performance?<br>
**A:** Absolutely not. `GJS` here is used to put together the GUI during startup.
It has nothing to do with video rendering. All used `GTK4` and `GStreamer` libraries are in C.
Even the custom video widget that I prepared for this player (based on original `GTK3` implementation) is a compiled C code.
All these libs are acting "on their own" and no function calls from `GJS` related to video decoding and rendering are performed during playback.

**Q:** What settings should I set to maximize performance?<br>
**A:** As of now, player works best on `Wayland` session. `Wayland` users can try enabling highly experimental `vah264dec` plugin for improved performance (this plugin does not work on `Xorg` right now) for standard (8-bit) `H.264` videos.
It can be enabled from inside player preferences dialog inside `Advanced -> GStreamer` tab using customizable `Plugin Ranking` feature.
Since the whole app is rendered using your GPU, users of VERY weak GPUs might try to disable the "render window shadows" option to have more GPU power available for non-fullscreen video rendering.
