When implementing a custom filter (inheriting AudioFilter) the transform_ip_vfunc function gives read-only buffer.

See attached example.

Hi Manuel,
Thanks a lot for your report. Sorry it took so long to fix it. The problem was copy_metadata_vfunc. I've fixed it (https://git.gnome.org/browse/gstreamermm/commit/?id=3f5fe44d45f4c2cefd0731bbd874a9bc9ae2dc5c) so you can use latest master branch.

This problem has been fixed in the unstable development version. The fix will be available in the next major software release. You may need to upgrade your Linux distribution to obtain that newer version.
