Sorry I didn't answer properly last time. It's hard to tell why Totem
isn't working, that's why gst-launch-0.10 is useful so you can try
step by step to reproduce the same pipeline that Totem is using.

If I understand correctly you have this issue with totem and playbin
in gst-launch-0.10, but when you manually specify the pipeline then it
works, right?

One reason could be that the priority of the sink is very low by
default, so it's not automatically used by playbin. You can check the
priority with gst-inspect-0.10, if it's too low you will need to
modify gstomx.c. The priority is low by default because sinks are not
well tested, you could say they are in "experimental" state.
