Dashcam

SW running on a RaspberryPi based dashcam.

Getting started

Prerequisites

This application relies on the Picamera2 library for dealing with the cameras. Before setting up the virtual environment it is necessary to have it installed system wide. If the library is not installed please follow the instructions here: Picamera2

Setup venv

• Setup a python virtual environment and use the system python packages:

  sudo apt install python3-virtualenv
  python3 -m venv --system-site-packages env
  

• Activate virtual environment:

  source env/bin/activate
  

Picamera2 should be available from the system packages.

Install dependencies

pip install cython

Install package

• Read only

python3 setup.py install

• Editable

  • Build extensions (this is needed for MSGQ)

    python3 setup.py build_ext --inplace
    

  • Install package via pip

    pip install -e .
    

Remarks

It is known when playing the recored video with e.g. VLC they seem to be laggy. To avoid this a simple post-processing can be run using ffmpeg specifying the frame rate can be applied

ffmpeg -r 25 -i video.h264 video.mkv
