# ESP32 MJPEG Streaming Server
This is a simple MJPEG streaming webserver implemented for AI-Thinker ESP32-CAM and ESP-EYE modules.
This is tested to work with **VLC** and **Blynk** video widget.
Inspired by and based on this Instructable: [$9 RTSP Video Streamer Using the ESP32-CAM Board](https://www.instructables.com/id/9-RTSP-Video-Streamer-Using-the-ESP32-CAM-Board/)
