How to draw/display Jpeg on my TFT screen

[muekno]

I know there is a drawJpg function. but I can get it to work. Maybe some one has an example or hint how to make it work.
Situation: I get a stream of Jpegs from an ESP32 CAM (AI Thinker model) via Websockets.
The contents of the message is the Jpeg 320x240. Now how to get this poicture on the screen.

I appreciate any help or hint!

Kind Regards

Hi,

I get a stream of Jpegs

sounds like those aren't JPEG images but MJPEG frames

lgfx::drawJpg() won't work with MJPEG data, what you need is a MJPEG decoder, either as an esp-idf component registry or as an arduino library.
