Advanced Desktop Media Player built using Python, PySide, PyQt, and Qt Designer – QT Media Player

QT Media Player is an advanced desktop media player developed using Python, PySide, PyQt, and Qt Designer. This tutorial will provide you with a step-by-step guide on how to create a fully functional media player application with all the necessary features such as play, pause, stop, volume control, seek control, playlist management, and more.

Before we get started, make sure you have the following installed on your system:

1. Python (https://www.python.org/downloads/)
2. PySide (https://wiki.qt.io/Qt_for_Python)
3. PyQt (https://riverbankcomputing.com/software/pyqt)
4. Qt Designer (https://www.qt.io/)

Now, let’s start building our media player application:

Step 1: Create a new project in Qt Designer

Open Qt Designer and create a new project. Choose "Main Window" as your template and save the .ui file in your project folder.

Step 2: Design the UI

Design the UI for your media player application in Qt Designer. Add widgets such as buttons, labels, sliders, and a video player widget to the main window. Customize the appearance of your media player as desired.

Step 3: Convert the .ui file to a Python script

Open a terminal and run the following command to convert the .ui file to a Python script using the pyuic tool:

pyuic5 -x your_ui_file.ui -o your_ui_file.py

This will generate a Python script that contains the UI code for your media player application.

Step 4: Create the main Python script

Now, create a new Python script in your project folder. In this script, you will write the main code for your media player application. Start by importing the necessary modules:

import sys
from PySide2.QtWidgets import QApplication, QMainWindow
from your_ui_file import Ui_MainWindow

Next, create a class for your media player application that inherits from both QMainWindow and the generated Ui_MainWindow class:

class MediaPlayer(QMainWindow, Ui_MainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)

Step 5: Implement the media player functionality

Now, you can start implementing the functionality of your media player application. Add methods for playing, pausing, stopping, adjusting volume, seeking, and managing the playlist. Here is an example code snippet for playing a video:

def play_video(self):
    self.mediaPlayer.play()

You can add similar methods for pausing, stopping, adjusting volume, seeking, and managing the playlist.

Step 6: Initialize the media player application

Create an instance of the QApplication class and the MediaPlayer class, and run the main event loop:

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MediaPlayer()
    window.show()
    sys.exit(app.exec_())

Step 7: Run the media player application

Save the changes to your Python script and run it in a terminal. Your media player application should open, displaying the UI you designed in Qt Designer. Test the functionality by playing a video file, adjusting the volume, seeking, and managing the playlist.

Congratulations! You have successfully created an advanced desktop media player using Python, PySide, PyQt, and Qt Designer. You can further enhance the functionality of your media player by adding features such as equalizer settings, subtitle support, playback speed control, and more. Experiment with different widgets and customizations to make your media player unique and user-friendly.
