I'm not aware of a general stream parsing tool, but the reference
decoder has a telemetry mode which will overlay block coding mode and
mv data. See http://people.xiph.org/~xiphmont/demo/theora/demo2.html
for an example of the output.

Make sure you the the cairo library development headers available and
configure libtheora with --enable-telemetry; then uncomment the
telemetry mode calls in player_example.c or add something similar to
your own decoder framework.
http://theora.org/doc/libtheora-1.2/theoradec_8h.html#decctlcodes has
brief documentation of the the visualization options.
