MJPEG Multiclient Streaming Server using RTOS queue to serve video to clients.

The problem with this approach is that the slowest connected client slows it down for everyone.

MJPEG Multiclient Streaming Server using dedicated RTOS tasks to serve video to clients.

This solves the problem of slowest client as every client is served independently based on their bandwidth. Slow clients are just not getting all the frames.

All captured frames are stored in PSRAM (until you run out of memory) and served to individual clients one after another, so every client is guaranteed to get all frames in order, at their own pace (good for recording without frame drops)

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

2. Delete examples folder from the archive

3. 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: Default, Minimal SPIFFS (or any other that would fit the sketch)
• PSRAM: Enabled

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 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.
