Implementing video playback in Android using OpenGL Texture with KivyMD in Python #android #video #opengl #kivymd #python 📹🎬

In this tutorial, we will learn how to implement Android Video view using OpenGL Texture in Kivy/KivyMD with Python. This will allow us to play videos in our Android applications using OpenGL rendering, which can offer better performance and smoother playback compared to traditional video rendering methods.

1. Set up your development environment:
   Before we begin, make sure you have Kivy and KivyMD installed in your Python environment. If you haven’t installed them yet, you can do so by running the following commands in your terminal:

pip install kivy
pip install kivymd

You will also need to have the Android development environment set up on your computer. You can refer to the official Android developer documentation for instructions on how to set up your environment.

1. Create a new Kivy application:
   Now, let’s create a new Python file for our Kivy application. Open your favorite code editor and create a new file called ‘main.py’.

In this file, we will define our Kivy application class and the layout that will contain our video player. Here’s an example of how your ‘main.py’ file might look:

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.video import Video
from kivy.clock import Clock

class VideoPlayerApp(App):
    def build(self):
        layout = BoxLayout()
        self.video = Video(source='path/to/your/video.mp4', state='play')
        layout.add_widget(self.video)
        Clock.schedule_interval(self.update, 1.0/60.0)
        return layout

    def update(self, dt):
        self.video._video_surface._video._update()

if __name__ == '__main__':
    VideoPlayerApp().run()

In this code snippet, we define a new Kivy application class called ‘VideoPlayerApp’ that contains a BoxLayout with a Video widget. We load a video file (‘path/to/your/video.mp4’) into the Video widget and start playing it.

1. Implement OpenGL Texture for video rendering:
   Now that we have our basic video player set up, we can improve the performance of video rendering using OpenGL Texture. To do this, we need to subclass the Video widget and override its _load() method to use an OpenGL Texture instead of the default texture provider.

Here’s an example implementation of an OpenGL Video widget:

from kivy.core.video import VideoBase
from kivy.graphics.texture import Texture
from kivy.uix.video import Video

class OpenGLVideo(Video):
    def _load(self):
        self._texture = Texture.create(size=self._video._texture_size)
        self._texture.blit_buffer(self._video._frame, colorfmt='rgba')
        self._video_surface._video.texture = self._texture

    def on_texture(self, instance, value):
        pass

class VideoPlayerApp(App):
    def build(self):
        layout = BoxLayout()
        self.video = OpenGLVideo(source='path/to/your/video.mp4', state='play')
        layout.add_widget(self.video)
        Clock.schedule_interval(self.update, 1.0/60.0)
        return layout

    def update(self, dt):
        self.video._video_surface._video._update()

if __name__ == '__main__':
    VideoPlayerApp().run()

In this code snippet, we subclass the Video widget and override its _load() method to create an OpenGL Texture and blit the video frame onto it. We then set the OpenGL Texture as the texture provider for the Video widget, which will improve the performance of video rendering.

1. Test your Android Video view implementation:
   To test your Android Video view implementation using OpenGL Texture, run your Kivy application on an Android device or emulator. You should see your video playing smoothly with improved performance compared to traditional video rendering methods.

That’s it! You have successfully implemented Android Video view using OpenGL Texture in your Kivy/KivyMD application with Python. Enjoy playing videos in your Android applications with better performance and smoother playback. 😍😍😍
