GStreamer on Qt for iOS

[Matthew Waters]

Are you missing 
https://gitlab.freedesktop.org/gstreamer/gst-examples/-/blob/master/playback/player/ios/GstPlay/gst_ios_init.m 
<https://gitlab.freedesktop.org/gstreamer/gst-examples/-/blob/master/playback/player/ios/GstPlay/gst_ios_init.m> 
and the corresponding .h file?  Everything is linked in statically on 
iOS and you need to manually declare and register each GStreamer plugin 
you want to use.

Cheers
-Matt
