[gst-devel] Where'd the timestamps go?

What i want is to copy a single jpeg image t some to be given timestamp from
a saved MJPEG-in-a-matroska-file a into a jpg file. Actually, to pick out a
list of individual frames from the saved stream and put them individually
into separate jpg files and then later to reassemble them. A crude foorm of
stream editing to be fancied up later.
My problem is that i just seem to be missing the ah-ha moment on writing
gstreams in programs. The book gets me mouth wateringly close but I can't
quite yet form the questions into word that it isn't answering. As I
learn/figure out more.... Unless someone wants to volunteer a pretty
complete example of connecting up sometimes and request pads in C. :-)
In the mean time, I'd like to analyze the stream-in-a-file outside gstreamer
to pick out the frame I want. So knowing where it stuck the timestamp would
help. Only problem is, where ever it is stuck it is not ASCII. A hex dump
of the file is massively unhelpful until you learn the flags and find where
the content "elements" are in the file. e.g. FFD8 starts a new jpeg.
