wcWebCamClient Library

This is a library for convenient client work with the wcWebCamServer server via the JSON protocol.

The structure of the client-server software package

The server designed to collect images and data streams from cameras (devices) and forwards messages between devices to control the periphery via an HTTP 2 connection is wcwebcamserver (Lazarus/Free Pascal). Abstract client for Lazarus is wccurlclient (Lazarus/Free Pascal). A detailed implementation of an external device based on "ESP32-CAM" is given in the example webcamdevice (С). The example of a desktop application for external device controlling and viewing images is webcamclientviewer (Lazarus). An example of an Android application for controlling external devices, chatting and streaming is wcwebcameracontrol (Java).
