YouTube Video Transcription Service

This Python application is a Flask web service that takes a YouTube video URL as input and returns a transcript of the audio using OpenAI's Whisper ASR API. It first downloads the audio from the YouTube video, splits it into 10-minute chunks, and then transcribes each chunk using the Whisper ASR API.

Dependencies

To use this application, make sure you have the following dependencies installed:

• openai: The official OpenAI Python library.
• pytube: A lightweight, dependency-free Python library for downloading YouTube videos.
• pydub: A simple audio processing library for Python.
• Flask: A lightweight WSGI web application framework.

You can install these dependencies using pip:

```bash pip install openai pytube pydub flask ```

Usage

1. Set up an OpenAI API key:

```bash export OPEN_AI_KEY=your_openai_api_key_here ```

2. Run the Flask application:

```bash python app.py ```

3. Make a request to the /transcribe endpoint with the YouTube video URL as a parameter:

```bash curl "http://localhost:5000/transcribe?url=https://www.youtube.com/watch?v=example" ```

4. The application will download the audio from the YouTube video, split it into chunks, transcribe each chunk using the Whisper ASR API, and return the transcript as a JSON object:

```json { "transcript": "your_transcription_here" } ```

Notes

• This application is for demonstration purposes only and is not suitable for use in production.
• The transcription accuracy depends on the quality of the audio and the performance of the Whisper ASR API.
• Keep in mind that long videos may take a significant amount of time to transcribe.
• Make sure you have the necessary permissions to download and transcribe the audio from the YouTube video.
