I found there is a memory copy in gstCamera, can it be removed?

When I studied the code of how to control mipi camera to do inference by gstreamer from below github, I saw there is a memory copy there. Can it be removed? If not, it means gstreamer pipeline is not a zero-copy pipeline?

Hi,
Please try tegra_multimedia_api. You can install samples via Jetpack and refer to

tegra_multimedia_api\samples\backend
tegra_multimedia_api\samples\frontend

@DaneLL
Thank you for your answer. So you means tegra multi-media api is the better or only choice for building zero-copy pipeline, right?
