Indeed. With my system 0.10.35 version the video plays fine for ikea, with git
0.10 branch (effectively equal to 0.10.36 at this point of time) it does not.
Does with playbin1 as you say.

But
gst-launch filesrc location=/tmp/ikea.mp4 ! qtdemux name=d ! queue ! h264parse
! ffdec_h264 ! ffmpegcolorspace ! videoscale ! xvimagesink  d. ! queue !
aacparse ! faad ! volume ! audioconvert ! audioresample ! pulsesink
doesn't play either for file2, while does for file1.

Removing the h264parse from in there makes it work.

So this is a regression due to some bug in h264parse, combined with the fact
that since 0.10.36 playbin2 auto-plugs parsers now, while in 0.10.35 it did not
do that yet.
