Google announced that starting from Android 15 Android devices will support 16KB page size. All the apps that have native code (including the libraries) need to be reconfigured and rebuilt. The part of the configuration is to update to NDK version r27.
However, GStreamer in its latest version 1.24.x supports only r25c.
Is there any work being done to make GStreamer compatible with Android 15 and 16KB Page size? If yes, what is the timeline?
I don’t think there are any plans. Sooner or later it will happen. You could create an issue in gitlab to track updating to a newer version.
