Video size when using glimagesink

[Patrick Fü]

Hey all, 

I'm wondering if there is a way to change the video size when using glimagesink. 

May pipeline is created with "playbin" and internally it uses "qtdemux" and "glimagesink".

The video is smaller then my screensize and I wanna make it fullscreen. 

I found the same question on the mailing list without an answer. 

Is it even possible  ? 

Thanks, 

Patrick

Yes. Through the VideoOverlay interface you pass a "native window", if
you resize this window on a supported windowing system, glimagesink
will scale the video maintaining aspect ratio.

To do this, you have to write code to integrate with your GUI toolkit
using GstVideoOverlay and use your GUI toolkit to fullscreen the
window.  glimagesink doesn't expose/support fullscreening with the
window system.

Hi Matthew,

On X11/linux platform, glimagesink will not response to _set_render_rectangle(). It will change the video size following the window system. But on wayland, it does because the _set_render_rectangle() is implemented.

Thanks
