gst-launch fdsrc fd=0 ! text/plain ! txt. videotestsrc ! textoverlay
name=txt shaded-background=yes font-desc="Serif 40" ! xvimagesink

would read the text from stdin. For some reason it does only for the
first line.

gst-launch fdsrc fd=0 ! text/plain ! txt. videotestsrc ! textoverlay
name=txt shaded-background=yes font-desc="Serif 40" wait-text=false !
xvimagesink

this does not wait, but the text gets cleared on the next frame again :/
