uxplayrc configuration file).</p></li>
<li><p>On macOS with this installation of GStreamer, the only videosinks
available seem to be glimagesink (default choice made by autovideosink)
and osxvideosink. The window title does not show the Airplay server
name, but the window is visible to screen-sharing apps (e.g., Zoom). The
only available audiosink seems to be osxaudiosink.</p></li>
<li><p>The option -nc is always used, whether or not it is selected.
This is a workaround for a problem with GStreamer videosinks on macOS:
if the GStreamer pipeline is destroyed while the mirror window is still
open, a segfault occurs.</p></li>
<li><p>In the case of glimagesink, the resolution settings “-s wxh” do
available are glimagesink (default choice made by autovideosink) and
osxvideosink. The window title does not show the Airplay server name,
but the window can be shared on Zoom. Because of issues with
glimagesink, you may find osxvideosink works better. The only available
audiosink is osxaudiosink.</p></li>
<li><p>The option -nc is currently used by default om macOS, This is a
workaround for window-closing problems with GStreamer videosinks on
macOS. In anticipation of fixes, this option can be canceled with “-nc
no”, if not needed.</p></li>
<li><p>In the case of glimagesink, the resolution settings “-s wxh” may
not affect the (small) initial OpenGL mirror window size, but the window
can be expanded using the mouse or trackpad. In contrast, a window
created with “-vs osxvideosink” is initially big, but has the wrong
aspect ratio (stretched image); in this case the aspect ratio changes
when the window width is changed by dragging its side; the option
<code>-vs "osxvideosink force-aspect-ratio=true"</code> can be used to
make the window have the correct aspect ratio when it first
opens.</p></li>
