  At which level ? Between input and output of decoder ? Which decoder
was it ? Maybe your *stream* actually requires 8 frames of latency. Is
it using B frames ?

  Based on everything you mention after ... it looks as though your
problem is not with GStreamer ... but with either the decoder

want to play back *requires* such a latency.
