How to Step Backward?

[Thomas Bond]

Hello,


     I'm using this method to step forward.

gst_event_new_step (GST_FORMAT_BUFFERS,framesToSkip, 1, TRUE, FALSE)


     What do I need to do in order to change direction to step backward?


     In my scenario I need to go back a frame and the go forward a frame 
so I end on the same frame I started from.

I need to do this to update post processing I'm doing when the video 
stream is stopped.


     Thanks in advance.
