Flask app to handle Blob uploads of MP4 files/images.

Flow

• User makes a network request to application with a Blob file as the body of the request
• The applicaiton keeps the request open, reads the blob, and saves the mp4 locally on the server _ blur_face_video.py scripg gets trigger and breaks up mp4 frame by frame
• Runs a model to find a face in the frame, blurs the face and writes new images into a new mp4
• Server sends back the new mp4 and deletes the original

Setting up Flask

• Make sure pip3 and python3 are set up on your computer
• Activate the virtual environment to set up the python interpreter

sh venv/bin/activate

• Install requirements from requirements file

pip3 install -r requirements.txt

• Export the name of the flask server file in your terminal session

export FLASK_APP=fb_server.py

• Run the server

python3 -m flask run

This should activate the server on port 5000

• Reference https://flask.palletsprojects.com/en/1.1.x/quickstart/ for details

Setting up Docker

• Run docker build -t faceblur .
• After the image has built, run docker run -p 5000:5000 -it faceblur
• The container should be serving over localhost 5000

To Do

• Deblob object send to pyscript
• Send data back as blurred video
• Create DockerFile for server code
• Set up ALB (with https) or APIGW to ping Server
• Set up CORS with app ID on either the server, the ALB or Both
