with a filesrc, a decodebin and a fakesink in a pipeline, I want to seek to some
frame number, get the frame data and then display it.

With an avi file, the seek is accurate, but the data that I retrieve when the
"handoff" signal is sent is not good.

You can see an example of the problem here :

With an mkv file, the seek is not accurate. It seems to go to the next key
frame, and not the previous one, before doing the seek. The problem with the
data remains.

The videos that I use are here :

the video stream has been encoded with xvid.

The above screen shot is obtained with the blood.avi file, frame #120 and with
the program attached below
