flask-raspi-video-streamer

Flask-RESTful API to create and serve up a live-stream from a raspberry pi to web and android clients.

Original code borrowed/altered from miguelgrinberg/flask-video-streaming.

Android client is available at robsmall/raspi-video-streamer-app.

Set Up A Virtual Environment To Run The App Using Virtualenv On A Pi

Install virtualenv on the pi as root

$ sudo pip install virtualenv

Then, create a .env virtual environment

$ virtualenv .env

and use it

$ source .env/bin/activate

Then, install all the requirements for the pi

$ pip install -U -r requirements-pi.txt

Set the CAMERA environment variable to use the pi camera for android

$ export CAMERA=pi_android

Now you are good to run the app using

$ python app.py

To Run Using Gunicorn

Instead of running the app directly using python, run

$ gunicorn --threads 5 --workers 1 --bind 0.0.0.0:5000 app:app

TODO

• This is currently set up for pi_android, hook everything else up to work properly too.
• Get this to work with web clients or allow for running of the one-off simple_mjpeg-server.py script.
