Can i use for the usb camera live streaming on 8 bit parallel line interface ili9486 lcd which function will be use for the live streaming of this library ?

nopnop2002 commented 1 year ago

JPEG display is slow, so live streaming display is impossible.

A display speed of about 15 FPS is required for live streaming.

This display speed is impossible with ESP32.

It is possible if it is about 1 FPS.

It is necessary to create a new MPEG reception function.

I have this lcd , It's possible live streaming on this lcd using lovyanGFX library ?

Thank you

USB-CAMERA outputs MPEG (=JPEG).

USB-CAMERA--->JPEG---(HTTP)-->ESP32--->8 bit parallel line interface.

in code where i should have to be change ?

You have to write a lot of new code.

A display speed of about 15 FPS is required for live streaming.

However, with the CPU power of ESP32, 1 FPS is the limit.

JPEG display on SPIFFS is here. https://github.com/nopnop2002/esp-idf-parallel-tft/blob/main/main/main.c#L840
