Python Qt : simple tiktok downloader.

Today, simple example with PyQt6 and yt_dlp.

Get the link from tiktok browser and use it to download the video for your storage.

I used the Copilot tool. It seems to know the Romanian language. For a developer, comments and source code are not an impediment, because it is very simplistic.

Let's see the source code:

from PyQt6.QtWidgets import (
    QApplication, QWidget, QVBoxLayout, QHBoxLayout, QPushButton,
    QLineEdit, QLabel, QFileDialog, QListWidget, QListWidgetItem,
    QProgressBar, QMessageBox
)
from PyQt6.QtCore import Qt

class TikTokDownloader(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("TikTok Downloader (yt-dlp)")
        self.setMinimumWidth(600)

        self.url_input = QLineEdit()
        self.url_input.setPlaceholderText("Introdu URL TikTok...")

        self.folder_input = QLineEdit()
        self.folder_input.setPlaceholderText("Folder download...")

        browse_btn = QPushButton("Selectează folder")
        browse_btn.clicked.connect(self.select_folder)

        fetch_btn = QPushButton("Caută stream-uri")
        fetch_btn.clicked.connect(self.fetch_streams)

        self.stream_list = QListWidget()
