Pipeline Freezes When Adding In Tee With x264enc

Hello all,

I am running into a very odd problem with using x264enc and tees.  It is
worth mentioning that I am working on Windows.

I have the following pipeline that runs fine.

gst-launch -v videotestsrc ! tee name=mytee ! queue ! ffmpegcolorspace !
x264enc ! fakesink

However, when I try to attach another element to the tee (in this case an
autovideosink element), the pipeline freezes and shows only one frame of
video.  For example,

gst-launch -v videotestsrc ! tee name=mytee ! queue ! ffmpegcolorspace !
x264enc ! fakesink mytee. ! queue ! autovideosink

Does not work.  It will print out the normal caps information and then
nothing else happens.  This seems to be a very straight forward pipeline
that should work relatively easy.  Is there something I am missing here or
is this an error with gstreamer?

Thank you for your help,
William
