OS: win7
My simple player works well with SDL 2.0.3 , but once I change SDL2.DLL to 2.0.9 , it does not work and I debug into the source and find that the spec.format does not match the wanted.format. You can see the source codes in ffplay.c.

After that I run ffplay(4.1) and got the err infor as the title.
In the end I run ffplay(4.1) in Win 8 and it works well.
