| ## Waveform Video Generator | |
| This project provides a web-based interface for generating waveform videos from audio files using Gradio. The application utilizes FFmpeg and ImageMagick to overlay captions and customize the appearance of the waveform. The environment is set up using a Docker container for ease of deployment. | |
| ### Features | |
| - Upload an audio file to generate a waveform video. | |
| - Customize the background color, foreground opacity, bars color, number of bars, and bar width. | |
| - Option to add a caption text overlay on the waveform video. | |
| ### Installation | |
| To run this project locally, ensure you have Docker installed and follow the steps below: | |
| ```bash | |
| # Clone the repository | |
| git clone <repository-url> | |
| cd <repository-name> | |
| # Build the Docker container | |
| docker build -t waveform-video-generator . | |
| # Run the Docker container | |
| docker run -p 7860:7860 waveform-video-generator | |
| ``` | |
| The Gradio interface should be accessible at `http://0.0.0.0:7860` in your web browser. | |
| ### Usage | |
| 1. Upload your audio file. | |
| 2. Customize the waveform video by adjusting the parameters: | |
| - Background Color | |
| - Foreground Opacity | |
| - Bars Color | |
| - Number of Bars | |
| - Bar Width | |
| - Caption Text (optional) | |
| 3. Click on the submit button to generate the waveform video. | |
| 4. Download the generated waveform video. | |
| ### Code Overview | |
| #### app.py | |
| The core functionality of the application is defined in the `app.py` file. The `Predictor` class contains the `predict` method, which generates the waveform video using Gradio, FFmpeg, and ImageMagick. The Gradio interface is configured to accept various input parameters to customize the waveform video's appearance. | |
| #### Dockerfile | |
| The `Dockerfile` sets up the required environment to run the application. It installs system dependencies such as FFmpeg and ImageMagick, as well as the necessary Python packages. The Docker container ensures that all necessary dependencies are available and configured correctly. | |
| ```dockerfile | |
| FROM python:3.9-slim | |
| # Install system packages | |
| RUN apt-get update && apt-get install -y \ | |
| ffmpeg \ | |
| imagemagick \ | |
| fontconfig \ | |
| && apt-get clean \ | |
| && rm -rf /var/lib/apt/lists/* | |
| # Install pip packages | |
| RUN pip install gradio==3.50.2 | |
| # Set environment variables for matplotlib and fontconfig | |
| ENV MPLCONFIGDIR=/tmp/matplotlib | |
| ENV FONTCONFIG_PATH=/etc/fonts | |
| # Create needed directories with correct permissions | |
| RUN mkdir -p /tmp/matplotlib /usr/share/fonts /src/fonts /root/.config /src/flagged && \ | |
| chmod -R 777 /tmp /usr/share/fonts /root/.config /src/fonts /src/flagged | |
| # Copy the rest of the application code | |
| COPY . /src | |
| # Set the working directory | |
| WORKDIR /src | |
| # Set the entry point to run the prediction script | |
| ENTRYPOINT ["python", "app.py"] | |
| ``` | |
