KLV stream not detected

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.
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).
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:
Topology:
container: MPEG-2 Transport Stream
video: H.264 (High Profile)
audio: MPEG-2 AAC
unknown: meta/x-klv
Properties:
Duration: 0:00:02.276393185
Seekable: yes
Live: no
Tags:
language code: en
audio codec: MPEG-2 AAC
video codec: H.264
-----------------
And this for ffprobe:
Input #0, mpegts, from '/tmp/test1.mp4':
Duration: 00:00:02.47, start: 3600.000000, bitrate: 1424 kb/s
Program 1
Stream #0:0[0x41]: Data: klv (KLVA / 0x41564C4B)
Stream #0:1[0x42](en): Audio: aac (LC) ([15][0][0][0] / 0x000F),
48000 Hz, stereo, fltp, 106 kb/s
Stream #0:2[0x43]: Video: h264 (High) (HDMV / 0x564D4448),
yuv420p(tv, bt709, progressive), 1920x1080 [SAR 3:4 DAR 4:3], 30 fps,
14.58 tbr, 90k tbn, 60 tbc
Unsupported codec with id 100356 for input stream 0
-------
If you can get me your file, I'll see what I get as well. Maybe we can
figure this out....
