It's just that when a not-negotiated flow error happens, the not-negotiated
flow is passed upstream to the element driving the pipeline, in this case
oggdemux. That's why the demuxer posts the error message. The error happens
somewhere else though.


According to the log and the graph there seems to be something wrong with
negotiation / fixation somewhere.

The problem is that audioconvert turns the stereo into mono, which it then
feeds to the faac encoder. But the capsfilter after the encoder wants
channels=2, so when faac outputs channels=1 AAC, this generates a
not-negotiated.
