The app also has Nginx configured which lets users in your local network access the app using your local IP address. 6 | 7 | ## Requirements 8 | If you want to run the app on docker the only thing you need is Docker-ce and Docker-compose. 9 | follow the official [guide]("https://docs.docker.com/engine/install/ubuntu/") on installing Docker on Ubuntu. 10 | 11 | If you only want to run the python program use the following command to install requirements. 12 | 13 | ``` 14 | cd flask/ 15 | pip install -r requirements.txt 16 | ``` 17 | ### Run 18 | Flask web app only: cd to `flask` directory and run the following: 19 | 20 | ``` 21 | python run.py 22 | ``` 23 | Run the whole thing on Docker and Nginx: cd to the project root directory and run: 24 | 25 | ``` 26 | docker-compose up 27 | ``` 28 | **Note**: Make sure you change the `CAMERA_STREAM_URL` in docker compose file under Flask service. Default is 0 but webcams are not accessible from a Docker container out of the box! So an RTSP url is required. 29 | 30 | It might take some time to download required docker images and then it will run the containers and you and other users in the local network can access the page on any device. Just type the local IP address of your machine in the browser and that's it! 31 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | Skip to content 2 | Search or jump to… 3 | 4 | Pull requests 5 | Issues 6 | Marketplace 7 | Explore 8 | 9 | @AryanSh98 10 | github 11 | / 12 | gitignore 13 | 3.2k 14 | 108k58k 15 | Code 16 | Pull requests 17 | 200 18 | Actions 19 | Projects 20 | Security 21 | Insights 22 | gitignore/Python.gitignore 23 | @pradyunsg 24 | pradyunsg Remove pip-wheel-metadata/ from Python.gitignore (#3364) 25 | … 26 | Latest commit 14f8a8b on Apr 12 27 | History 28 | 83 contributors 29 | @arcresu@shiftkey@Lucretiel@Harrison-G@jwg4@GabrielC101@misaelnieto@pmsosa@svkampen@vltr@thedrow@matheussl 30 | 138 lines (112 sloc) 1.99 KB 31 | 32 | # Byte-compiled / optimized / DLL files 33 | __pycache__/ 34 | *.py[cod] 35 | *$py.class 36 | 37 | # C extensions 38 | *.so 39 | 40 | # Distribution / packaging 41 | .Python 42 | build/ 43 | develop-eggs/ 44 | dist/ 45 | downloads/ 46 | eggs/ 47 | .eggs/ 48 | lib/ 49 | lib64/ 50 | parts/ 51 | sdist/ 52 | var/ 53 | wheels/ 54 | share/python-wheels/ 55 | *.egg-info/ 56 | .installed.cfg 57 | *.egg 58 | MANIFEST 59 | 60 | # PyInstaller 61 | # Usually these files are written by a python script from a template 62 | # before PyInstaller builds the exe, so as to inject date/other infos into it. 63 | *.manifest 64 | *.spec 65 | 66 | # Installer logs 67 | pip-log.txt 68 | pip-delete-this-directory.txt 69 | 70 | # Unit test / coverage reports 71 | htmlcov/ 72 | .tox/ 73 | .nox/ 74 | .coverage 75 | .coverage.* 76 | .cache 77 | nosetests.xml 78 | coverage.xml 79 | *.cover 80 | *.py,cover 81 | .hypothesis/ 82 | .pytest_cache/ 83 | cover/ 84 | 85 | # Translations 86 | *.mo 87 | *.pot 88 | 89 | # Django stuff: 90 | *.log 91 | local_settings.py 92 | db.sqlite3 93 | db.sqlite3-journal 94 | 95 | # Flask stuff: 96 | instance/ 97 | .webassets-cache 98 | 99 | # Scrapy stuff: 100 | .scrapy 101 | 102 | # Sphinx documentation 103 | docs/_build/ 104 | 105 | # PyBuilder 106 | .pybuilder/ 107 | target/ 108 | 109 | # Jupyter Notebook 110 | .ipynb_checkpoints 111 | 112 | # IPython 113 | profile_default/ 114 | ipython_config.py 115 | 116 | # pyenv 117 | # For a library or package, you might want to ignore these files since the code is 118 | # intended to run in multiple environments; otherwise, check them in: 119 | # .python-version 120 | 121 | # pipenv 122 | # According to pypa/pipenv#598, it is recommended to include Pipfile.lock in version control. 123 | # However, in case of collaboration, if having platform-specific dependencies or dependencies 124 | # having no cross-platform support, pipenv may install dependencies that don't work, or not 125 | # install all needed dependencies. 126 | #Pipfile.lock 127 | 128 | # PEP 582; used by e.g. github.com/David-OConnor/pyflow 129 | __pypackages__/ 130 | 131 | # Celery stuff 132 | celerybeat-schedule 133 | celerybeat.pid 134 | 135 | # SageMath parsed files 136 | *.sage.py 137 | 138 | # Environments 139 | .env 140 | .venv 141 | env/ 142 | venv/ 143 | ENV/ 144 | env.bak/ 145 | venv.bak/ 146 | 147 | # Spyder project settings 148 | .spyderproject 149 | .spyproject 150 | 151 | # Rope project settings 152 | .ropeproject 153 | 154 | # mkdocs documentation 155 | /site 156 | 157 | # mypy 158 | .mypy_cache/ 159 | .dmypy.json 160 | dmypy.json 161 | 162 | # Pyre type checker 163 | .pyre/ 164 | 165 | # pytype static type analyzer 166 | .pytype/ 167 | 168 | # Cython debug symbols 169 | cython_debug/ 170 | © 2020 GitHub, Inc. 171 | Terms 172 | Privacy 173 | Security 174 | Status 175 | Help 176 | Contact GitHub 177 | Pricing 178 | API 179 | Training 180 | Blog 181 | About 182 | 183 | .vscode/ 184 | .idea/ --------------------------------------------------------------------------------
