VideoService 0.1.2

A library to create video services

---

:vhs: VideoService

The library you needed to create your own Video Service

VideoService is a python library focused on the BackEnd for Video Services, such as YouTube (Note that this library is not used in YouTube, it is just an example).
VideoService uses a JSON DataBase to manage all the Videos on the server and its not dependant on external libraries to work (except for OpenCV and Lingua), all functionalities depend on bare Python libraries.

:arrow_down: Install package

Make sure you running on Python 3.12 (No support for other versions now)

PIP

• If you want user intended version, run:pip install VideoService

• If you want tester intended version, run: pip install VideoService[dev]

Cloning repository

1. Clone this repository or download it
2. Put the VideoService folder on your project folder
3. You're good to go

:memo: Working On

Currently working on the version compatibility of the library (I will test down to 3.8)
Started debugging and doing the Example files for giving further documentation and explanation on how to use the library

I will add support for PlayLists/Series, on the next version of the library, but first we need the first deploy.
A Languages API will also be released to make it easier to have language support, instead of having the dictionaries in your own server

Here is an extensive documentation of how VideoService library works and how to use it.
