Hi,

I want to check with FFplay if input file is an image (jpg/png/tiff etc.).
How can I do it to be 100% sure?

I need to "refresh" SDL window with bigger images than desktop resolution,
because without that I get only part of the image displayed in the SDL window
(probably libSDL bug). When I resize SDL window manually, I can see full
image.

Here is how I check for images bigger than 1024 width:

if(((is->video_st->codec->width)>1024) && (!is->audio_st) &&
(!is_full_screen))

but I know it's not the best solution, because videos can also have
width>1024.

Regards
