Check the GStreamer debug logs, they will contain all informations about
why negotiation has failed in that pipeline. But maybe it all works
already if you add h264parse in front of the muxer.

Note however that h264 inside AVI is never going to work properly
because of design constraints in AVI. Better use a modern container
format.
