<p>I am running Ubuntu 16.04.4 LTS. I also get GStreamer Core
Library version 1.15.0.1 when I do a --gst-version on
gst-discoverer-1.0.</p>
<p>You are correct that gst-discoverer-1.0 does not show the klv
stream but ffprobe DOES show it as Stream #0:1 (I've highlighted
the text in red below in your email).</p>
<p>I think we need to do an Apples-to-Apples test here. I've
attached a short clip I've made with audio, video and klv data.
My system shows this for gst-discoverer-1.0:</p>

<p>And this for ffprobe:</p>

If you can get me your file, I'll see what I get as well. Maybe we
can figure this out....<br>
