Hello,

I'm finding a way for making rounded video frame using gstreamer.
For example, when composing two video frames with compositor element,
I hope one inner stream can have rounded edge
(like https://helpx.adobe.com/indesign/how-to/round-corners-frame.html is
describing)

+-----------+                       +---------------+
|               |      +------+       |  /-----\         |
|     V0      |  +  |  V1  |  =    | |  V1 |        |
|               |      +------+       |  \-----/  V0   |
+-----------+                        +--------------+
Is there any video filter for that in gstreamer (without opengl) ?
I think videomixer, videobox, and compositor has no ability for that.
