-------------------------------------+-------------------------------------
 When using ffplay to play WMV2 video and using -ss seconds parameter to
 set starting play time, but ffplay can't position the specified time to
 start playing.  For example, when I use 'ffplay -ss 9' command to play the
 video,  ffplay always starts playing from the begining and does't play it
 from 9s.
