KLV stream not detected

[Arturo Flores]

Hi John,

I built gstreamer using the "create-uninstalled-setup.sh" script on Ubuntu
16.0.4.3 .  The output of gst-discoverer-1.0 is :
GStreamer Core Library version 1.15.0.1

If I run gst-discoverer-1.0 on a file with KLV stream I get:
0:00:00.239696518 [332m22597[00m 0x7fe3b40358f0 [31;01mERROR  [00m [00m

Note it still does not detect the klv stream.  The output of ffprobe on the
same file:

Could it be I built gstreamer incorrectly or without the right
autogen.sh/configure flags?
