Thank you. When testing, remember to:
* make sure the "dev" libraries for gstreamer 1.0 and gstreamer-video 1.0
are installed (on Ubuntu, that's libgstreamer1.0-dev and
libgstreamer-plugins-base1.0-dev)
* run "autoconf"
* pass --enable-gstreamer as a flag to "./configure" (it's disabled by
default. Should it be?)
