gst-launch-1.0 videotestsrc ! glupload ! video/x-raw\(memory:GLMemory\) !
gldownload ! videoconvert ! osxvideosink
Setting pipeline to PAUSED ...
2017-10-03 17:02:27.904 gst-launch-1.0[5433:232813] !!! BUG: The current
event queue and the main event queue are not the same. Events will not be
handled correctly. This is probably because _TSGetMainThread was called for
the first time off the main thread.
Pipeline is PREROLLING ...
Got context from element 'gldownloadelement0': gst.gl.GLDisplay=context,
gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayCocoa\)\ gldisplaycocoa0";

This displays a window with green screen instead of video test source. I'm
on OSX and I have been facing a lot of problems with GStreamer installation.
