Developing VideoUtils

This involves

• Creating a python virtual env.
• Downloading the source code from GitHub
• Installing all the dependencies
• Installing the package in dev mode.

For example these are steps I typically do on my windows machine.

python -m venv venv_dev_spvideoutils  
env_spvideoutils\Scripts\activate
git clone https://github.com/sanjeevs/spvideoutils.git
cd spvideoutils
pip install -r requirements.txt
pip install -e . 

I can check that the env is correctly setup by invoking any of the scripts above from the same window.

>video_capture
usage: video_capture [-h] [--index INDEX] [--time TIME] outfile
video_capture: error: the following arguments are required: outfile

Creating a distribution package

Check the resource packaging.python.org on how to buiild the distribution.

• Bump the version of the software in setup.py
• Run the script to create the distribution in a new folder called dist.

python setup.py bist_wheel

This is done by publishing the changes to pypi. It involves the following steps.

• This is a pure python project and so a wheel distribution is required. Source distribtution (sdist) is for packages with C extensions.

• Use twine to upload the source distribution.

twine upload dist/*
