Problem with porting playbin in a pipeline from Gst-0.10 to Gst1.0

[Victor henri]

Hi Tim

gst-launch works perfectly both with mp3 or flac (gst-play doesn't because it says the gst-play command is not found, although I have the  gstreamer1.0-plugins-base-apps package installed...).
My app can be compiled against both gst-0.10 and -1.0 but to be sure, I removed the gstreamer-0.10-dev to be sure it is compiled against gst-1.0 for sure.

Actually the playbin used alone in my code plays perfectly mp3 or flac files. The problem comes when I want to have its sink (via the sink GstGhostPad) in the pipeline composed by the several elements I have put in it (equalizers, audiochebband, spectrum, autoaudiosink and some others)...

I have tried on another Ubuntu system (13.10 version). I have the same problem.

Cheers

Victor
