conversion from JPEG to RGB

Hi,

I need to write a c code in Linux to convert video data from JPEG to RGB in
order to display on an LCD. Been searching but I can't find any helpful
leads. 

Any helpful suggestion is most welcomed.

Thanks in advance

No, you don't. The reference implementation that everyone uses is
http://www.ijg.org/. If you are working in Linux I'd suggest using
SDL, which would mean you don't need to go back to the primary
sources; use http://www.libsdl.org/projects/SDL_image/. Putting an
image up onscreen is a few lines of code.

sdl (as already said)
gtk

I think that "fbv" is a useful linux application for such jobs.
