Multimash

This is a Python script for creating a mashup of songs of your favorite singer from YouTube videos. The script allows you to specify the name of the singer, then it downloads multiple songs, extracts their audio, and concatenates the audio tracks into a single output file. The program utilizes the pytube, moviepy, glob, and youtube_search libraries, as well as Python's built-in threading and multiprocessing modules.

How it works

1. Input Parameters

   The script takes command-line arguments to configure its behavior:

   • singer_name: The name of the singer for a search query for YouTube videos.
   • num_videos: The number of YouTube videos to download and process. (Should be more than 10)
   • audio_duration: The duration of the audio clip to be extracted from each video (in seconds). It should be between 20 and 90 seconds.
   • output_filename: The output file name for the final mashup audio in mp3 format.

2. Video Download and Audio Extraction

   The script searches for YouTube videos based on the input singer_name using the YoutubeSearch library. It then proceeds to download each video in parallel using threading. The pytube library is used to download the stream of each video. After downloading, the script extracts the audio from each video clip using moviepy and saves it as a separate mp3 file in the "Audios" directory.

3. Mashup Generation

   Once all the audio clips are extracted, the script concatenates them using moviepy to create a single audio file representing the mashup. The final audio file is saved in the output specified in the command-line arguments.

Prerequisites

• Python 3.x

• The following Python libraries must be installed:

  • pytube
  • moviepy
  • youtube_search

  You can install these libraries using pip:

  pip install pytube moviepy youtube-search-python
  

Usage

Run the script from the command line with the required parameters:

python Mashup.py <singer_name> <num_videos> <audio_duration> <output_filename>

Notes

• For optimal runtime performance, it is recommended to set num_videos equal to the number of CPU cores in your machine. However, the script will run correctly even if this condition is not met.
• The script checks if the output_filename ends with .mp3. If not, it will display an error message and terminate.
• The "Videos" and "Audios" directories will be created automatically to store the downloaded video files and extracted audio clips, respectively.
• The final mashup audio will be saved with the specified output_filename in the current working directory.
