Do not call SDL_SetVideoMode() with the same size as previously
as this blanks the window.

I think the problem is that under amigaos, in fullscreen mode, the borderless window
with the size of image is opened (so as a result 0 is always returned when the user
try to toggle the screen), but on windows or linux the image is resized to the screen
resolution, so 0 is not returned and everything works correctly, but...

to reproduce the problem please run ffplay with your screen resolution (for example
"ffplay -x 1280 -y 1024 a.jpg") and press the "f" key - this will not work as on amigaos.

The "black screen" problem is easier reproductable with this file:

ffplay Cevennes1.j2k


ffplay -vlowres 1 Cevennes1.j2k
