[FFmpeg-user] Will you pls give me some advice? // A question: ffplay can not play from the given time

[chenct1976 at sina.com]

Hello everybody,
I played the file Wildlife.wmv(Win7 OS Sample Videos) by using ffplay comand, but it can not play from the given seconds.
OS: Win7 32Bit + Wingw
ffplay version: V0.10
Command line: ./ffplay_g -i Wildlife.wmv -ss 2
Expected result: play the video file from the 2nd second.
Test result: play from 0 second.
Is it a ffplay's bug? or the tested file has problem? 

Thanks in advance!
