gstreamer1-gst-plugins-base (macPorts) fails to provide the opengl plugin (libgstopengl.so)

[fduncanh]

For non-X11 users, the only videosink apparently available in the MacPorts gstreamer-1.0 installation ("universal" variant) is osxvideosink.

Am I missing something in installation (some variant specification?)

The standard macOS one (glimagesink) is not present, because the opengl plugin is missing from the GStreamer installation.

Other distributions (HomeBrew and "official" Gstreamer for macOS) provide opengl.

"gst-inspect-1.0 opengl" will show whether or not the opengl plugin is installed.

Is this a feature (maybe opengl is not supported in "Aqua"?) or a bug?

If it's a bug, it's perhaps related to ​https://trac.macports.org/ticket/69787
