-# Example for the startup-problem
-#
-# The Pipeline will start but the test-image will be still, as long as no
-# ShmSink at /tmp/grabber-v is present (run ../test-grabber-src.sh in another shell)
-#
-# Even though the ShmSrc is not linked to anything and logically not required for
-# the videotestsrc or the ximagesink, the whole pipeline won't startup when this element
-# fails to start.
-#
-# once the pipeline is running, it does not matter what happens to the ShmSink on the
-# other end, because the TestBin filters all EOS and ERROR Messages coming from the ShmSrc,
-# but somehow this is not enough to make the pipeline start in an error-condition..
