Live streams vs Files?

Thanks. The gst-launch version of my pipeline (which works) is as follows:

gst-launch-1.0 --gst-debug-no-color --gst-debug=*:8 \
  bin. '(' name=reader \
    ximagesrc display-name=:1 use-damage=0 ! videoconvert !
'video/x-raw,pixel-aspect-ratio=(fraction)1/1,framerate=(fraction)25/1,format=(string)YUY2'
\
    ! identity \
    ')' ! \
  bin. '(' name=videostub \
    queue ! videoflip ! valve ! tee ! \
    bin. '(' name=videostream \
      queue ! videobox ! videoscale ! xvimagesink display=:5 \
    ')' \
  ')'




Here's a pair of .png graphs. One from gst-launch showing
the above pipeline in a working state, and one from my program
(named 'vaal') showing the actual state of things once I enter the
PAUSED state.

And finally, here's a full-blown debug trace of me running the program
and it getting all the way into the playing state without actually
ever delivering any data to the output screen:
