Hi and Welcome

SDL www.libsdl.org is a cross platform game development API. It allows you to write (almost) the same code on Windows, Linux, Mac OSX etc.

SDL is mainly a 2D library but it have functions to use Opengl with it. There are alsoa number of other SDL libraries available for images (sdl_image), sound (sdl_sound), networking (sdl_net), Mixing (sdl_mixer), play movies (smpeg), the list goes on.

JEDI-SDL are the units that you will need to use if you want to use SDL from Delphi/FreePascal/Kylix etc. There are numerous units available for all of the libraries above and more (ODE, FMOD,Newton etc) as well as a whole host of examples.

Can you write the app you mentioned Well yes (not sure about the quicktime part) SDL_image can handle most popular image formats, smpeg can play mpeg movies, SDL_flic and handle flic animations.

Hope this all helps
