I have a simple gstreamer pipeline which looks like :

| Filesrc | --> | PngDec | --> | ImageFreeze | --> | Queue | --> | Compositor | --> | Fake Sink |

location (input) of the filesrc is a png file of size 400 X 600.

In the pipeline how do I get the width and height of the file? (400 X 600)

You check caps between connections and read out the widht and height fields. – Florian Zwoch Jul 27 '20 at 11:47
@FlorianZwoch - Thanks a lot for the suggestion and checking the caps does reveal the image dimensions. – user1918858 Jul 28 '20 at 20:39

Well depends between which elements you check and what you do. That is how elements know about dimensions too.. – Florian Zwoch Jul 28 '20 at 21:18
