--- Comment #9 from Carlos Rafael Giani <dv at pseudoterminal.org> ---
There is one corner case that I haven't been able to figure out yet. Take this
pipeline:

  gst-launch-1.0 fakesrc filltype=5 sizetype=fixed sizemax=4096 !
"audio/x-raw,rate=44100,channels=2,format=S16LE,layout=interleaved" !
rawaudioparse ! fakesink sync=true

In this case, rawaudioparse receives stream-start , and then immediately
afterwards data. This is because fakesrc is operating in pull mode. If
can-activate-pull=false is added to fakesrc, it works. The question is how to
catch this properly, or if it even makes sense to do so.

Also, if I replace rawaudioparse with audioconvert for example, it works. I
guess this is because audioconvert operates in push mode.
