You should get all compiler flags and linker flags / libs via
pkg-config. Maybe something like this will work:

  gcc `pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-1.0` \
      -O0 -g3 -Wall -c -o test-video test-video.c

You might need to set LD_LIBRARY_PATH to /opt/lib/xyz or put it
into /etc/ld.so.conf* and run sudo ldconfig.
