Hi all, hi have a little problem when I do a gst_play_location (); the
next song doens't always (doesn't always +-= never) start well, it has a
little gap at the begining. 
Looking at the ticks, for the second song the ticks starts sometimes at
nearly 0.7-0.8 second, and stays at that value for may be 4-5 ticks  (a
tick is 200MS). This is when the song has a gap.

To expose my problem you can try with a modified version of
examples/gstplay/player.c with the patch attached

Here is the ouput:
