FastFoward and FastRewind Issue with Gstreamer

Iam developing a media player  using Qtgstreamer . 



Below APi  is been used for Seek functionality.But for fastforward and
FastRewind   functionality not working properly with these Api.

 gst_event_new_seek(rate, static_cast<GstFormat>(format),
static_cast<GstSeekType>(startType), start,
static_cast<GstSeekType>(stopType), stop );


Oggdemux and vorbisdec are used  to play Ogg files.For  oggstreams
fastforward and rewind is working,,but when you consider the performance
,I have observed that  there is  a delay in switching from rewind state
to fastforward state. Observed that  there is a time delay  if you press
on fastforward when the stream actually doing a backward seek....


But for other streams like  AAC,Wma,MP3 with  FFMpeg support
fastforward and rewind is not working...pipeline stops playing when
there is switch from fastforward state to Rewind state..



Can anyone please let me know what is the exact  seekApi  to be used.


How is the performance with opensource codec with gstreamer in case of
fastforward and fastrewind.



Thanks & Regards
