Cant Play Video

[ksharindam]

When I am trying to play any video, such as /opt/vc/src/hello_pi/hello_video/test.h264 it show this error.
And the video is not played.

Traceback (most recent call last):
  File "./pyopenmax.py", line 1004, in <module>
    play("/opt/vc/src/hello_pi/hello_video/test.h264") 
  File "./pyopenmax.py", line 983, in play
    vp = VideoPlayer(videofile)
  File "./pyopenmax.py", line 863, in __init__
    read_media.change_state(OMX_StateIdle)
  File "./pyopenmax.py", line 592, in change_state
    raise ValueError("State not reached")
