<p class="MsoNormal">I am using Wayland/Weston with GTK and trying to write a Python script to display video on the screen. I have a GTK window with a grid and I just add the widget below to the grid. Video is very choppy. It looks much smoother if I play
it from Linux command line using <span style="font-size:10.5pt;font-family:Consolas;color:#5D6A6F;background:#FDF6E3">

<p class="MsoNormal">I saw mentions of “waylandsink” that can be used instead of “gtksink”, but I couldn’t figure out how to use it, since I don’t know how to get Gtk.Widget from “waylandsink”. I can get it to display in its own window, but I need to be able
to control where it goes on the screen.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone have any examples of how to use “waylandsink” with GTK? I don’t have XWayland on my box. Any other suggestions on how to make playback less choppy?<o:p></o:p></p>
