Hi,
Look at the GstVideoAggregator base class, it can be used to build this kind of element. You can look at compositor for a complete example.

I want to make a custom plugin for stitching N sinks to 1 src. And the frame size of src is base on the frame size of input.

But actually I know little about this.
I have looked through the videomixer gstramer-good plugin.
But it is too complex for my target.
I just I want to use a fixed caps pad with only one video format.
I seems the GstCollectPads should be used to control the flow.
But which methods should be implemented?
Can Is there anyone can give me some advice?
Thanks very much!
