simple pipeline 1.0.7 vs 1.2.0

[Marco Micheletti]

Hello ,

I have a problem with a simple pipeline working with gstreamer1.0.7 but not
working after updating everything to 1.2.0 .

A simplified version of the pipeline can also be tested with the gst
-launch :

"gst -launch- 1.0 audiotestsrc ! faac ! flvmux streamable = true ! fakesink
"

I'm testing the two different versions by using a symbolic link between two
different folders

Can someone help me to understand where is the problem ?

This is a part of the trace debug
