How to build custom gstreamer libs for Android using cerbero

Newcomers

I’m trying to build Android libs with some changes to
cerbero/build/sources/android_universal/arm64/gstreamer-1.0/subprojects/gst-plugins-bad/ext/webrtc/gstwebrtcbin.c
However, the changes don’t take any effect when I run
./cerbero-uninstalled -c config/cross-android-universal.cbc build gst-plugins-bad-1.0
I might be doing this the wrong way. Any help? Thanks!

See https://gitlab.freedesktop.org/gstreamer/cerbero/#how-to-build-a-custom-gstreamer-repository-or-branch for how to build a custom GStreamer version with cerbero.

Is it possible to use a local repo? For example,

recipes_remotes = {'gstreamer-1.0': {'custom-remote': '~/Documents/gstreamer'}}
recipes_commits = {'gstreamer-1.0': 'custom-remote/1.6'}

Yes. Use the file:///home/USER/Documents/gstreamer form for the git repo remote.

It seems not be working. I’m using

./cerbero-uninstalled -c localconf.cbc -c config/cross-android-universal.cbc build gst-plugins-bad-1.0

to build a specific lib. What’s the difference between package and build?

Sorry my bad, I mistyped the branch name :pensive_face:

Ok it’s not working again. Code changes won’t take effect :weary_face: How can I enforce code fetching?

Also, when I use the generated libs in cerbero/build/dist/android_universal/arm64/lib, the libs just behave like nothing changes (I simply added some extra logs). This is frustrating…
