Avtp plugin?

[RioChan]

Hi.
#1. I have install the libavtp, log is like below.
#2. But, I'm fail to use the gstreamer to test with avtp.

Hi @RioChan,

I'm a bit confused, did you build gstreamer after installing libavtp? Note that you need to build gstreamer, which will then find libavtp and build itself with the AVTP plugin.

[RioChan]

Hi edersondisouza :
Thanks for the feedback.
Sorry, I never know the sequence as your saying.
Let me double confirm: The AVTP needs to be installed after Gstreamer installed?

BR Rio

[RioChan]

Hi edersondisouza :
#1. please see the build / test log as the below.
#2. I have deleted the libavtp and re-installed/built the libavtp.
But the Gstreamer found not avtp.

May you comment how to solve this?
Thank you very much.

[edersondisouza]

You definitely need to build gstreamer. Are you building it? If so, can you share the log from gstreamer build, please?

[RioChan]

Hi edersondisouza:
#1.
Thanks for continuing helping me, appreciated.
I have re-built the gstreamer with 1.19.2, full built log is as the bottom.

#2.
But, the below cmd still found no avtp.
gst-inspect-1.0 avtp
No such element or plugin 'avtp'

#3. however, test with dummy cmd as the below is working, I think my problem is how to find the plugin.

Hi,

There's no need to worry about gstreamer vs gst-plugins-bad anymore, since the monorepo. Try following these instructions https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-meson.html?gi-language=c#setting-up-the-build-with-meson. It should build all of gstreamer, including the avtp plugin, quite transparently.

If that doesn't work, just post the logs =D

[RioChan]

Hi.

I can perform: meson test -C build:

Hi,

Can you share the steps you are using to build gstreamer? If I do these steps:

git clone git@gitlab.freedesktop.org:gstreamer/gstreamer.git
cd gstreamer
meson build

I'll see this in the middle of the logs:

So, gstreamer just downloads libavtp if it doesn't find it on the system. Can you share (on pastebin) the full log generated by the meson build step of gstreamer, so we can see what is doing wrong?

[RioChan]

Hi edersondisouza:

Sorry for replying late due to vocation.

#1, Thanks for your new git site for me, It seems better than my previous git.
This is my problematic git of Gstreamer: git clone https://github.com/GStreamer/gstreamer.git
This is yours: git clone https://gitlab.freedesktop.org/gstreamer/gstreamer.git

   Obvious, your gitlab gstreamer is better than my used one, I don't know why the reason.
   May you teach me why there are difference between them?

  At least, I know your gitlab gstreamer will auto git clone the Gstreamer bad/base/ugly....plugins.
  My previous one github is ........

#2. This is my part of the logs.

I tried to build the subprojects/gst-plugins-good, it shows me this error.
Do I need to fix this first?
But I don't know how to fix it :(.

Found pkg-config: /usr/bin/pkg-config (0.29.1)
Dependency gstreamer-1.0 found: NO found 1.14.2 but need: '>= 1.20.0'
Found CMake: /usr/local/bin/cmake (3.16.5)
Run-time dependency gstreamer-1.0 found: NO (tried pkgconfig and cmake)
Looking for a fallback subproject for the dependency gstreamer-1.0

meson.build:255:0: ERROR: Neither a subproject directory nor a gstreamer.wrap file was found.

A full log can be found at /opt/gstreamer/subprojects/gst-plugins-good/build/meson-logs/meson-log.txt

Hi,

May you teach me why there are difference between them?

Not sure, as the github one should be a mirror of the gitlab one. Anyway, gitlab is the official one for gstreamer.

About the compilation errors, I'd guess it's about the compiler version you're using. Nevertheless, if you are not using those parts of gstreamer (Qt from the failing logs), you could do something like meson -Dgst-plugins-good:qt5=disabled so not to build Qt support. You can find more information on how to enable/disable parts of gstreamer build here: https://gitlab.freedesktop.org/gstreamer/gst-build/blob/master/README.md

Finally, I don't think you're supposed to go inside the subproject directory to build only it - refer to the link above for more details on how to build gstreamer.

Hi Ederson:

Sorry for replying late.
I have tested some ubuntu versions with Gstreamer.
Only the ubuntu 22.04 can make it compiled finished and the UI screen of the ubuntu won't be black.

Now, I'm going to test the Gstreamer.
I confirm my gstreamer has the "videotestsrc".
But, testing it will show me the "no element of the videotestsrc".
May you guide me how to solve this?

I have read almost > 50 articles by google.
None of them fixes my issue. :(.

[edersondisouza]

It seems that you are having problems with gstreamer itself, not the avtp plugin. Maybe try asking on gstreamer forums, mailing list, IRC?
