Installation & Run

These services must be installed, configured and running:

• Python (>= 3.6)
• FFmpeg
• MongoDB
• RabbitMQ (celery backend)

After required services were installed and started, you can proceed with a video server installation.

Installation for development

NOTE: Use virtualenv and pip to install python modules.

# clone project
git clone https://github.com/superdesk/video-server.git

# install video server for development
# NOTE: your virtualenv must be activated
pip install -e video-server/[dev]

Run video server for development

Video server consists from two main parts: http api and celery workers.

For starting an http api dev server:

1. Set FLASK_ENV env variable to development:

export FLASK_ENV=development

2. Run python -m videoserver.app

For starting a celery workers:

1. Run celery -A videoserver.worker worker

Running tests

NOTE: You can run tests only if project was installed for development!
There are several options how you can run tests:

1. Run tests directly from your virtualenv.
   Execute pytest from video server root.

pytest

if you want to get a coverage report into your terminal screen

pytest --cov-report term-missing --cov

2. Run tests using tox.
   It runs tests for each python version specified in .python-version file.
   tox-pyenv plugin is used, so python versions from .python-version must be installed in yours pyenv. Just execute tox from video server root.

Installation for production

Video server is a module, but not ready to use instance.
For ready to use installation, please refer to the README file at: https://github.com/superdesk/video-server-app
