decodebin - static linking of decoder and sink

I tried adding a videoconvert but it made no difference, will have to get the log tomorrow and let you know.
The pipeline graph was created by "gst-launch-1.0 filesrc location=out.h264 ! h264parse ! decodebin ! xvimagesink". Where out.h264 is a single IFrame.

Get a debug log and check where the not-negotiated comes from. Most
likely you need at least a videoconvert between decoder and sink.
Also your pipeline graph is *not* from decodebin but from your manual
