Is there existing element for features like camera digital zoom?

I think digital zoom just cut central part of video/image content, and another videoscale element could fit that to final display.

But when I go through gst-inspect output, I haven’t found any existing element does it.

Anyone knows whether similar elements exist?

Thanks BR

Probably 'videocrop' element is what you are looking for.

It would be cool, if you/someone would merge videocrop ! videoscale !
capsfilter as a videozoom element as this could be more efficient (e.g.
work in place).
