Tim, how does the -v option work on gst-launch? I haven't seen anything that seems to relate to that in the elements I have worked with but I know that it generates output that otherwise isn't displayed.

It should be stream-format=byte-stream, not avc. If it's avc, add an .... ! video/x-h264,stream-format=byte-stream ! ... after the encoder.
