Raspberry Pi 3 B Decode and render image with GLES2

[stefano.setti]

I am new with graphic programming and what I am trying to do is to decode and display with HW acceleration a JPEG on screen in specific position and dimension without X11.
All example that I found doesn't work (https://www.raspberrypi.org/forums/view ... 6#p1555166), I always get this error when compile:

Code: Select all

/usr/bin/ld: video/VideoObjects/VideoObjectGLES2_EGL.o: undefined reference to symbol 'eglCreateImageKHR'
/usr/bin/ld: //opt/vc/lib/libbrcmEGL.so: error adding symbols: DSO missing from command line

I am using Raspbian GNU/Linux 10 (buster).
Someone can help me to fix the error or better give some example to achieve what I need?

Thanks.

The linked code sounds overly complicated. Also you don't necessarily need GL for any of that. You might have a look at a rather small tool I wrote in 2015: https://github.com/info-beamer/tools/tr ... r/showjpeg. Modifying the dst_rect should allow you to place it freely on the screen.
