In this tutorial, we will be learning how to use the Python tool You-Get along with the PyQt library to create a simple YouTube video downloader for the popular Chinese video-sharing website, Bilibili. We will be using You-Get to download the videos from the website, and PyQt for the user interface.
This tutorial assumes that you have a basic knowledge of Python and PyQt. If you’re not familiar with either, I recommend going through some beginner tutorials before starting with this one.
-
Installing the necessary libraries:
First, we need to install You-Get and PyQt. You can install You-Get using pip by running the following command in your terminal or command prompt:pip install you-get
For PyQt, you can install it using the following command:
pip install PyQt5
-
Setting up the PyQt GUI:
We will start by creating a simple PyQt GUI that will allow the user to input the Bilibili video URL and download the video. Create a new Python script and import the necessary PyQt modules:from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QLineEdit, QPushButton, QVBoxLayout import sys
-
Setting up the main window:
Next, we will create a class for our main window and define the layout and widgets. Add the following code to your script:class BilibiliDownloader(QWidget): def __init__(self): super().__init__() self.setWindowTitle("Bilibili Downloader") self.setGeometry(100, 100, 400, 100) layout = QVBoxLayout() self.url_input = QLineEdit() layout.addWidget(self.url_input) self.download_button = QPushButton("Download") layout.addWidget(self.download_button) self.setLayout(layout)
-
Connecting the download button:
Now, we need to connect the download button to a function that will use You-Get to download the video. Add the following code to your script:self.download_button.clicked.connect(self.download_video) def download_video(self): url = self.url_input.text() command = f"you-get -o downloads {url}" os.system(command)
-
Running the application:
Lastly, we will create an instance of our BilibiliDownloader class and run the PyQt application. Add the following code to your script:if __name__ == "__main__": app = QApplication(sys.argv) window = BilibiliDownloader() window.show() sys.exit(app.exec_())
- Running the downloader:
Now, when you run your script, a simple PyQt window will appear where you can input the Bilibili video URL and click the "Download" button to download the video. The video will be saved in a folder named "downloads" in the same directory as your script.
Congratulations! You have successfully created a simple Bilibili video downloader using You-Get and PyQt. You can further enhance the functionality by adding features like progress bars, error handling, or downloading multiple videos at once. Feel free to customize the application to suit your needs. I hope you found this tutorial helpful and informative. Thank you for reading!
