Procedure:

1. Download latest ZIP file from https://github.com/espressif/esp32-camera.git into the esp32-cam subfolder

2. unzip using unzip -j esp32-cam-master.zip command. This will place all files in the same folder

   NOTE: please observe the -j flag: the sketch assumes all files are in the same folder.

In esp32-cam.ino sketch select your camera pin assignment.

The choices are:

• CAMERA_MODEL_WROVER_KIT

• CAMERA_MODEL_ESP_EYE

• CAMERA_MODEL_M5STACK_PSRAM

• CAMERA_MODEL_M5STACK_WIDE

• CAMERA_MODEL_AI_THINKER

Compile the esp32-cam.ino sketch using the following settings:

• ESP32 Dev Module
• CPU Freq: 240
• Flash Freq: 80
• Flash mode: QIO
• Flash Size: 4Mb
• Partition: Minimal SPIFFS (or any other that would fit the sketch)
• PSRAM: Enabled

Results:

I was able to run multiple browser windows, multiple VLC windows and connect multiple Blynk video widgets (max: 10) to ESP-EYE chip. The delay on the browser window was almost unnoticeable. In VLC you notice a 1 second delay probably due to buffering. Blynk performance all depends on the phone, so no comments there.

This is incredible considering the size of this thing! The camera on ESP-EYE is actually quite good.

Enjoy!
