md5sum music.mp3
If the pipeline contains an md5sink element, gst-md5sum will query it
for the md5sum at the end of pipeline iteration.
If it doesn't contain an md5sink element, gst-md5sum will automatically
connect an md5sink to the right hand side of the given pipeline.
The pipeline should be incomplete, that is, a final sink element
should be omitted, so that gst\-md5sum can connect the pipeline to
an md5sink element.
See the man page for gst\-launch or the GStreamer docuementation for
more information on how to create a PARTIAL\-PIPELINE\-DESCRIPTION.
