Video and Audio Downloader

This project is a Streamlit application that allows users to search for videos on YouTube, download them, convert them into audio files, trim the audio, and combine multiple audio files into a single output. The app leverages yt_dlp for video and audio downloading and ffmpeg for audio processing.

Features

1. Video Download:

   • Search for videos on YouTube using a query.
   • Download a specified number of videos.

2. Audio Conversion:

   • Convert downloaded videos into MP3 audio files.

3. Audio Trimming:

   • Trim a specified number of seconds from the beginning of each audio file.

4. Audio Merging:

   • Combine trimmed audio files into a single MP3 file.

5. Interactive UI:

   • User-friendly interface built with Streamlit for seamless interaction.

How It Works

1. User inputs:

   • Search Term: The query for the videos (e.g., "machine learning course").
   • Number of Videos: The number of videos to download.
   • Trim Audio: The number of seconds to trim from the beginning of each audio file.

2. The application:

   • Searches and downloads videos using yt_dlp.
   • Converts the videos to MP3 audio files.
   • Trims the specified seconds from the beginning of each audio file.
   • Combines all trimmed audio files into a single output file.

Usage

1. Launch the Streamlit app.
2. Enter the search term, number of videos to download, and the trim duration.
3. Click on "Download and Convert".
4. The application will:
   • Download the specified videos.
   • Convert them into audio files.
   • Trim the audio as specified.
   • Merge the audio files into a single MP3 file.

The downloaded videos and audio files will be saved in the following directories:

• Videos: ~/Desktop/ML-course-downloads
• Audio Files: ~/Desktop/ML-course-audiofiles

Configuration

FFmpeg Setup

• Update the ffmpeg_path variable with the correct path to the ffmpeg.exe file.
• Ensure ffmpeg is installed and added to your system's PATH.

Output Directories

• Videos are saved in ~/Desktop/ML-course-downloads.
• Audio files are saved in ~/Desktop/ML-course-audiofiles.

Limitations

• The application relies on yt_dlp for video downloads and may be subject to YouTube's rate limits.
• The provided ffmpeg path must be correctly configured for audio processing.

Future Enhancements

• Add support for downloading playlists.
• Allow users to specify audio quality and format.
• Add progress tracking for downloads and conversions.
