[gst-devel] Pipeline with live and non-live sources and sinks

We have a problem constructing a pipeline with live and non-live
sources and sinks. The following pipeline results audible scratches or
"jumps" during playback:
gst-launch-0.10 filesrc location=/tmp/test.mp3 ! decodebin !
audioconvert ! autoaudiosink autoaudiosrc ! audioconvert ! wavenc !
It may be buffer under-run or latency issue. It does not happen every
time but usually and it occurs especially at the beginning of the
stream. The recorded wav is perfect.
According to design documentation, the above pipeline should work
and even preroll:
However, gst-launch handles the pipeline purely as a live source and
skips prerolling. That happens also in an application that constructs
the same pipeline.
Any idea what should be changed? Thanks a lot in advance!
