conversion from JPEG to RGB

Started by najafa August 10, 2010
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.

I think that "fbv" is a useful linux application for such jobs. -- Best Regards Ulf Samuelsson These are my own personal opinions, which may or may not be shared by my employer Atmel Nordic AB
