<div>Yes, for non-linux platforms. It
doesn't mean that gst-build can't do it, just that gst-build
requires more setup and is not as regularly tested for this case
:).<br>
<br>
We do have a docker-based CI for the cross-mingw cases already
that you may want to borrow: <a href="https://gitlab.freedesktop.org/gstreamer/gst-ci/-/blob/master/docker/cerbero/Dockerfile-fedora" target="_blank">https://gitlab.freedesktop.org/gstreamer/gst-ci/-/blob/master/docker/cerbero/Dockerfile-fedora</a>

<div>That's cool! We'd love to see those
improvements/suggestions.<br>
<br>
It is possible to develop with cerbero however the
required steps are a little bit more involved.<br>
<br>
For branches that track git (all GStreamer recipes and
some others), what I personally do is push a branch to the
cerbero local sources of the specific project (on linux by
default is at '$HOME/.cache/cerbero-sources/$project').
'./cerbero-uninstalled show-config' will tell you exactly
where.<br>
<br>
Then either, change the branch in the recipe, or add a
'$HOME/.cerbero/cerbero.cfg' file (python syntax) with
something like the following (where the values are a git
commit reference, branch names in this case).<br>
<br>
```<br>
recipes_commits = {<br>
# "libusrsctp" : "hang-fix",<br>
"gst-plugins-base-1.0" : "egl-display-debug-cat",<br>
# "gstreamer-1.0" : "fail",<br>
"gst-plugins-bad-1.0" : "amcvideodec-gl-sync-meta-copy",<br>
# "gst-validate" : "android",<br>
# "gst-editing-services-1.0" : "android",<br>
}<br>
```<br>
<br>
For tarball-based sources, creating a patch in the local
sources directory and then adding the patch to the recipe
is usually the goto move.<br>
<br>
Cheers<br>

<div>On the Cerbero v. meson front: my company relies on
windows a lot, and so I'm doing a lot of use of
GStreamer on Windows. I've got a lot of suggestions /
tweaks / etc. that I'd love to be able to contribute
to the project to better help people such as myself
who are doing things exclusively on Windows. It's my
understanding that cerbero is best for building what's
in master, but that if I want to do any sort of rapid
iteration / testing, meson is the route to go. So,
that's my driving force. <br>
<br>
And thanks again, mate. Your work on everything is
appreciated by a lot of people. </div>

<div>You also need to be careful with constructing
all of the necessary paths and environment
variables so that no system libraries are found
and that your custom build versions are found
instead. <a href="https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/master/cerbero/config.py#L450" target="_blank">https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/master/cerbero/config.py#L450</a>
contains a non-exhaustive list. There are also
platform-specific configurations that may modify
some of those values: e.g. for windows: <a href="https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/master/config/windows.config" target="_blank">https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/master/config/windows.config</a>
and then there may be recipe-specific workarounds,
e.g. for openssl: <a href="https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/master/recipes/openssl.recipe#L150" target="_blank">https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/master/recipes/openssl.recipe#L150</a>.<br>
<br>
Generally we would recommend the cerbero route as
it tries takes care of all of this for you. If
something doesn't work, we can attempt to fix it.<br>

<div>You need to have a cross-build of

I assume that the 'pkg-config --version

versions which would be built for linux,
not mingw.<br>

According to the error, the problem
