pip install google-cloud-vision==0.30.1

3. Install FFmpeg for video processing. On Linux, install by sudo apt-get install ffmpeg.

4. Put your Google Cloud Platform service account key in the root directory of this repository with a name gcp_service_account_key.json.

5. Execute main() function in main.py. The script will start by downloading the weights for gender and age predictor:

main(input_video_path="input.mp4",
     output_video_path="input_annotated.mp4",
     detection_start_time=2, detection_end_time=4,
     highlight_color="#00ff00", font="Montserrat-Bold.ttf", font_size=32,
     line_width_rectangle=4, line_width_face_parts=4, language=Language.english,
