I suggest you use GStreamer, you can build a video by pushing bitmap frames and it does everything else for you.
Otherwise, you can animate a DrawingArea. Set up a 60hz timer on your own. The timer callback simply calls gtk_widget_queue_draw_area() <https://developer.gnome.org/gtk3/stable/GtkWidget.html#gtk-widget-queue-draw-area>. Then, on the draw_func of your drawingarea you display the bitmaps, one after another. That's the simplest solution but can have lower timing quality Luca 2018-08-01 14:18 GMT+02:00 R0b0t1 via gtk-list <gtk-list@gnome.org>: > On Wed, Aug 1, 2018 at 3:45 AM, Paul Davis <p...@linuxaudiosystems.com> > wrote: > > > > 60Hz is a reasonable common refresh rate, but it's not universal, and you > > probably should not rely on it being the context in which your program > runs. > > > > ... I'm not, the update is driven by frame decoding elsewhere.
