-------------------------------------+-------------------------------------
 the crash happens after seeking a few times with the mouse

 below log is from ffmpeg git-ed68fd4 (9 Apr 2012) - looks like enabling
 sdl outdev at the same time disables output to the console here (mingw)

 (if it's libsdl's bug then maybe it's possible to workaround it somehow?)
