class=505041300-23052013>Thanks for the replies, I am currently working my way
through the documentation. My current goal is to take the dv1394src and simply
have it display on the screen so that I can confirm my devices are working
correctly. My end goal is to take this input, feed it through particular
pipelines and have it sink out in a form that my OpenFrameworks OpenCV project
can read the camera input. </SPAN></FONT></DIV>

<DIV dir=ltr>Continuing from Ian, the approach is to consider both the source
and the sink, then simply plumb the needed parts between. Some of the lingo is
technology specific, so there is a learning curve. Post your requirements and we
can help. There are a lot of options...<BR></DIV>

<DIV text="#000000" bgcolor="#FFFFFF">Hi Mitch,<BR><BR>You should think of
GStreamer rather like a collection of LEGO bricks. Put them together the
right way and you can make anything you want.<BR><BR>Your example has merely
specified where it should get its input from - but you haven't specified what
you want to do with it.<BR><BR>Take a look at the documentation (<A
href="http://gstreamer.freedesktop.org/documentation/"
target=_blank>http://gstreamer.freedesktop.org/documentation/</A>) and skim
through the Application Development Manual. Although this is labelled
"Read This First", it does dive straight into programming - but look at the
section "Utility applications provided with GStreamer" and the section on
gst-launch. Also, look at the man pages on gst-launch.<BR><BR>At the
very least, you will need some sort of 'sink' to take your video stream and
display it somewhere, maybe xvimagesink. You may need to process the
video and store it using 'filesink'.<BR><BR>When you read about the individual
elements, many of them will give examples of a pipeline to make use of them
which you can then adapt to handle your source.<BR><BR>Hope that
helps<BR><BR>Ian
