KLV stream not detected

I have a file that contains two streams: a video stream and a klv stream. One problem I have encountered is it appears the KLV stream is not being detected when using gstreamer-1.0 . For example, if I use gst-discoverer-0.10 on this file I get:

...

Done discovering file://somefilewithklv.mpg

Topology:

container: MPEG-2 Transport Stream

video: H.264

unknown: private/klv

...

However, if I use the new gstreamer tool gst-discoverer-1.0, I get:

Done discovering file:///somefilewithklv.mpg

Topology:

container: MPEG-2 Transport Stream

video: H.264 (Baseline Profile)

I am using gstreamer-1.0-1.14.1 if it makes a difference. Should I be seing the unknown:private/klv stream when using the new gst-discoverer-1.0 ?

Thanks

Arturo

Re: KLV stream not detected

It works correctly on 1.15.0.1. It must be a bug in 14.:

Re: KLV stream not detected

Thanks, where would I get 1.15.01? I only see 1.14.01 here: https://gstreamer.freedesktop.org/data/pkg/windows/ . Is it possible this is working in previous versions (pre 1.14)?

Re: KLV stream not detected

In reply to this post by jhanksv

btw, I tried downloading a few other versions of gstreamer (1.10, 1.12, 1.13 ), I'm observing the same behavior in those versions too. Should I be able to detect the KLV stream?

Why do you say it's undetected ? This lines indicated it is. It says
unknown, because it does not fit in any of the 3 categories discoverer
knows, which is video/audio/text.

Re: KLV stream not detected

Hi Nicolas,

The output I've observed in all of the gstreamer1.x versions I've tried (up to 1.14.1) is:

Done discovering file:///somefilewithklv.mpg

Topology:

container: MPEG-2 Transport Stream

video: H.264 (Baseline Profile

John Hanks says he observed the "unknown: meta/x-klv" line in gstreamer 1.15.0.1 . I don't have that version, and I don't know where to get it. If you know where to get it, please let me know.

Thanks

Arturo

1.15 is not a real version. Odd minor identify development branches. 1.15 is the current development branches, toward next stable branch 1.16. if you can't wait to get a new feature, try and identify the patches that added this feature, and then you can backport into your project.

Thanks

Sorry for the late response - I've been out of town.

I am running on Linux and did a git update (git pull origin). The git repository updated to 1.15 a couple of weeks ago.

Re: KLV stream not detected

Thanks, would this be the master branch here https://github.com/GStreamer/gstreamer ?

Are nightly windows builds of master available anywhere? I can figure out how to build it on windows if necessary, but if there is something like a nightly build for windows available somewhere, I would use that option instead.

Why do you say it's undetected ? This lines indicated it is. It says
unknown, because it does not fit in any of the 3 categories discoverer
knows, which is video/audio/text.

Re: KLV stream not detected

For whatever reason, it looks like I used

git://anongit.freedesktop.org/git/gstreamer/$module

to grab my initial install and just do 'git pull origin' to get updates.

I found a script from last August that used this as the source and this is also in the gst-plugins-good.doap file in my gst-plugins-good build directory. I haven't has a need to learn too much a git so I'm not sure how different this might be from what is on github (or how to tell).

Are nightly windows builds of master available anywhere? I can figure out how to build it on windows if necessary, but if there is something like a nightly build for windows available somewhere, I would use that option instead.

Re: KLV stream not detected

In reply to this post by jhanksv

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:

Re: 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:

And this for ffprobe:

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

Re: KLV stream not detected

In reply to this post by Arturo Flores

Hi John,

If I run gst-discoverer-1.0 on the file you sent me, it does detect the KLV stream, I get

Topology:

container: MPEG-2 Transport Stream

video: H.264

audio: MPEG-2 AAC

unknown: meta/x-klv

However, on my file, the stream is still not detected. Unfortunately I don't think I can attach the file.

When I use the gst-discoverer-0.10 on the same file, I observe:

gst-discoverer-0.10.exe file.mpg

So it does detect the klv stream, but it also reports some errors. It's possible this file was incorrectly encoded. Perhaps gstreamer 0.10 was more tolerant to errors in the stream?

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

I am using gstreamer-1.0-1.14.1 if it makes a difference. Should I be seing the unknown:private/klv stream when using the new gst-discoverer-1.0 ?

Re: KLV stream not detected

The errors you see are indeed video encoder related. SPS/PPS/VPS headers are
missing (or at least they are not present at the beginning of the
bitstream). Alternatively, the stream did not start with a key frame.
Without these headers and/or a starting keyframe, the decoder has no clue
how to parse/decode the video.

This isn't very clear, what did you try ? And how did it failed ?

These are warning in 1.0, that's all. Just set GST_DEBUG=2, you'll
should get them.

Re: KLV stream not detected

In reply to this post by Arturo Flores

Re: KLV stream not detected

In reply to this post by Nicolas Dufresne-5

When I run gst-discoverer-1.0 on a file I have, I get:

gst-discoverer-1.0.exe \temp\file.mpg

Analyzing file:///temp/file.mpg

Done discovering file:///temp/file.mpg

Topology:

container: MPEG-2 Transport Stream

video: H.264

Properties:

Duration: 0:08:54.872310111

Seekable: yes

Tags:

video codec: H.264

If I run gst-discoverer-0.10 on the same file I get:

gst-discoverer-0.10.exe --gst-debug=0 \temp\file.mpg

Analyzing file:///temp/file.mpg

Done discovering file:///temp/file.mpg

Missing plugins

Topology:

container: MPEG-2 Transport Stream

video: H.264

unknown: private/klv

Properties:

Duration: 0:08:54.777058592

Seekable: yes

For some reason, on gst-discoverer-1.0 , it fails to detect the KLV stream for this particular file. However, gst-discoverer-1.0 does detect the KLV stream on the file John Hanks attached, so it seems the file I have has some issues (incorrectly encoded or something).

This isn't very clear, what did you try ? And how did it failed ?

These are warning in 1.0, that's all. Just set GST_DEBUG=2, you'll
should get them.

Re: KLV stream not detected

Ok thanks, it might not be possible to share due to its proprietary nature. I do appreciate the feedback I've received thus far, it has been helpful. I suspect it is an issue with this particular set of files I have.

With MPEG TS, you can cut out a very small part, just enough to
reproduce, which is generally enough to avoid the reproduction claims
(e.g. .5 of a second). But you decide.
