## Required libraries

This plugin uses [GStreamer](https://gstreamer.freedesktop.org/) internally.

```Shell
$ sudo apt install libglib2.0-dev libgstreamer1.0-dev
# Install as needed.
$ sudo apt install libgstreamer-plugins-base1.0-dev \
    gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
    gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav
```

## Usage

### pubspec.yaml
```yaml
dependencies:
  video_player: ^2.4.7
  video_player_elinux:
    git:
      url: https://github.com/sony/flutter-elinux-plugins.git
      path: packages/video_player
      ref: main
```

### Source code

Import `video_player` in your Dart code:
```dart
import 'package:video_player/video_player.dart';
```

### Enable GstEGLImage

If GstEGLImage is enabled on your target device, adding the following code to `<user's project>/elinux/CMakeLists.txt` may improve playback performance.

```
add_definitions(-DUSE_EGL_IMAGE_DMABUF)
set(USE_EGL_IMAGE_DMABUF "on")
```

### Customize for your target devices

To improve the performance of this plugin, you will need to customize the pipeline in the source file. Please modify the source file and replace the `videoconvert` element with a H/W accelerated element of your target device to perform well.

`bool GstVideoPlayer::CreatePipeline()` in packages/video_player/elinux/gst_video_player.cc
