            Bug ID: 790242
           Summary: Tutorials all can't show video on macOS
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal

     GNOME version: ---

See https://github.com/sdroege/gstreamer-rs/issues/58 , same applies to the C
tutorials.

The problem is that for osxvideosink and glimagesink we need to run a NSRunLoop
on the main thread on macOS. Our patched GLib version does that when you run a
GMainLoop (upstream GLib doens't!), but the examples are only using
gst_bus_timed_pop_filtered() so that also wouldn't help.

Using a GMainLoop would make the tutorials quite a bit more complicated, more
API would have to be introduced, there would always be callbacks, etc.


Not sure what to do about this!
