Problems with gst-plugins-bad and Cerbero

Hi,

I have a docker image with GStreamer built using Cerbero.

I want to add some logs in gstwebrtcbin.c to better understand how it works but when I try to follow the documentation to recompile gst-plugins-bad I end up not seeing my change in place (Even though it was compiled properly)

I think the problem is my --prefix since I'm running inside cerbero-unstalled but I tried a bunch of paths with no success

Any help will be much appreciated

Re: Problems with gst-plugins-bad and Cerbero

There is currently an unresolved bug related to debian package paths: https://bugzilla.gnome.org/show_bug.cgi?id=796009

A likely solution is described in the bug related to a ~/custom.cbc file (part of Matthew Thyer's proposed solution).

However, if you just want to rebuild and re-install the one package, this is faster (assuming you are on Linux):

cd gst-plugins-bad
./autogen.sh
make
sudo make install && sudo ldconfig

Re: Problems with gst-plugins-bad and Cerbero

Hi and thanks for the quick reply!

I tried to compile GStreamer directly in Ubuntu but I ran in a bunch of issues.

I ended up compiling it using Cerbero and using it inside cerbero-uninstalled shell.

My current problem is that I don't know where cerbero shell fetches the libs, and so far, the only solution I found was to fork gst-plugins-bad, change the remote url in the recipe and recompile.

I assumed that the prefix would delivery the libs into a folder and I could skip needing to fork, commit, etc

Regards

Hi,

Just to be sure cerbero is not really meant for use on Linux systems,
although it can be used like that of course and there is functionality
for generating packages in various formats. Most developers will use
something else on Linux system, whether yocto or just installation from
tarballs (with dependencies then provided by the base system/distro).

For development/hacking purposes I would recommend gst-build (Meson
based, the shiny new thing) in combination with the 'uninstalled'
target if desired, or gst-uninstalled (autotools-based). And
dependencies installed from distro packages then. This is what most
GStreamer developers use on Linux.

Tim,

Does the gst-build tool provide deb or rpm packages?

RE: Problems with gst-plugins-bad and Cerbero

In reply to this post by David Ing

I have now totally given up on Cerbero and have written a script that builds just the subset of GStreamer that I require from the released sources (not git). By setting the variables in the script correctly you can but some or all of GStreamer for the installation prefix of your choice.

The script is Ubuntu or at least Debian specific in that it installs the required prerequisite packages using “sudo apt install”.

Just look for the two comment lines that include “(assumes Ubuntu host)” if you want to modify this behaviour.

You’ll want to carefully consider the prerequisite packages and the arguments to configure for each GStreamer module to get your desired behaviour.

By default, the script will build in folder GStreamer release 1.14.1 for the prefix “/usr/local/gstreamer1.0” in the temporary build folder “~/build”.

By default it only builds the modules “gstreamer”, “gst-plugins-base”, “gst-plugins-good” & “gst-rtsp-server” as that’s what I require.

Note that if you build for a prefix other than “/usr/local” you’ll need to set LD_LIBRARY_PATH to include your prefix/lib or correctly link your application for the appropriate runtime library search path.

The script is:

#!/usr/bin/env bash

Tim et al,

I have been using cerbero for years to generate deb packages on Linux.
How much should I read into this implicit deprecation of that? I'm the
guy who asks every now and then if there's going to be a 1.x.y tag for
cerbero after gstreamer 1.x.y is released.... is that really 'cause I'm
the only one using it?

BTW is there going to be a 1.14.1 tag for cerbero? ;-)

Cheers,

Mark.

You shouldn't read anything into it.

If it works for you - great.

It wasn't clear to me from the original mail what the envisioned use
case was here. It's still worth pointing out that cerbero is not
something people use for development on Linux, and few for packaging on
Linux. That's not to say it can't be used like that of course. All
depends on what exactly is needed.

There will be a 1.14.1 tag once binaries are officially released. We're
still tracking down an issue on android.

Cheers

There is currently an unresolved bug related to debian package paths:  https://bugzilla.gnome.org/show_bug.cgi?id=796009

A likely solution is described in the bug related to a ~/custom.cbc file (part of Matthew Thyer's proposed solution).

However, if you just want to rebuild and re-install the one package, this is faster (assuming you are on Linux):

cd gst-plugins-bad

Hi,

I have a docker image with GStreamer built using Cerbero.

I want to add some logs in gstwebrtcbin.c to better understand how it works but when I try to follow the documentation to recompile gst-plugins-bad I end up not seeing my change in place (Even though it was compiled properly)

I think the problem is my --prefix since I'm running inside cerbero-unstalled but I tried a bunch of paths with no success

Any help will be much appreciated

RE: Problems with gst-plugins-bad and Cerbero

Trying again for a safer solution…

Replace line:

BUILD_ROOT="${BUILD_ROOT:-~/build}"

With the two lines:

BUILD_ROOT="${BUILD_ROOT/#\~/$HOME}"

BUILD_ROOT="${BUILD_ROOT:-${HOME}/build}"

Thanks for all the inputs!

I will give it a try and see how it goes

I have now totally given up on Cerbero and have written a script that builds just the subset of GStreamer that I require from the released sources (not git). By setting the variables in the script correctly you can but some or all of GStreamer for the installation prefix of your choice.

The script is Ubuntu or at least Debian specific in that it installs the required prerequisite packages using “sudo apt install”.

Just look for the two comment lines that include “(assumes Ubuntu host)” if you want to modify this behaviour.

You’ll want to carefully consider the prerequisite packages and the arguments to configure for each GStreamer module to get your desired behaviour.

By default, the script will build in folder GStreamer release 1.14.1 for the prefix “/usr/local/gstreamer1.0” in the temporary build folder “~/build”.

By default it only builds the modules “gstreamer”, “gst-plugins-base”, “gst-plugins-good” & “gst-rtsp-server” as that’s what I require.

Note that if you build for a prefix other than “/usr/local” you’ll need to set LD_LIBRARY_PATH to include your prefix/lib or correctly link your application for the appropriate runtime library search path.

The script is:

Re: Problems with gst-plugins-bad and Cerbero

In reply to this post by Matthew Thyer

Hi everyone,

I tried using meson and the script but it didn't work for me on Ubuntu

But since I learned a lot from both solutions, I was able to compile from source on Mac. I guess it was an environment issue or something.

Thank you all
