Gstreamer: macos

[esiqveland]

It looks like the libgst bindings may not work on aarch64 on macos.

I am running the PlaySound example:
https://github.com/jwharm/java-gi-examples/blob/main/PlaySound/src/main/java/io/github/jwharm/javagi/examples/playsound/PlaySound.java

When I try to run this sample, it works fine on Linux.

However on Macos:

(<unknown>:65383): GLib-GObject-CRITICAL **: 19:36:08.217: g_object_set_is_valid_property: object class 'GstFileSrc' has no property named '\xa8\u0003_\xf8\xb4o(\x8b\xbf\u0003\u001f\xf8\xb6\xe3{\xa9\xb8o8\x8b\xba\x83\\xf8\xac\x83^\xf8\xc2\u0012@x\xe1\u0007}\xb2B|\u0001\x9bA\u001f@\xf9! '

(<unknown>:65383): GStreamer-CRITICAL **: 19:36:08.231: gst_bin_add: assertion 'GST_IS_ELEMENT (element)' failed

Notice the strange property name in the logs from gst.

Crash:

[jwharm]

It's an issue with varargs handling on macOS AArch64. Thanks for the report.

Please note: This will take a while to fix correctly (plus I'm going to be offline for a while) but I will publish a preview release when this is fixed.

[esiqveland]

No worries, thank you for the great project!

[jwharm]

I published a 0.11.0-SNAPSHOT release with the fix.

For snapshot releases, add https://s01.oss.sonatype.org/content/repositories/snapshots to the repositories in your build script.
