GStreamer Tutorial 1 - hear sound but no video

I'm continuing my journey through GStreamer and am stuck once again. I'm running the first tutorial and can hear sound but no video.

The error that I'm seeing is:

gldisplay gstgldisplay_cocoa.m:175:gst_gl_display_cocoa_setup_nsapp: Custom NSApp initialization failed

Am I missing a plugin or some required library here? I'm on an M1 Mac.

I should note, that via the command line everything works just fine.

gst-launch-1.0 playbin uri="file:///Users/vukasin/Downloads/sintel_trailer-480p.webm"

Maybe this is OpenGL related? I'm guessing its trying, and failing to open the video.

I just figured out what was going on with this error after spending hours thinking my system was not setup correctly. This issue is that a GMainLoop must be ran for the windowing to work correctly from the main thread. Interesting enough the tutorial 12 does it correctly and does the same exact thing. https://gstreamer.freedesktop.org/documentation/tutorials/basic/streaming.html?gi-language=c
