Probe deepstream pipeline written by gstreamermm

Hi forum. I’m trying to use gstreamer c++ wrapper to write a class using some function of deepstream. For the probe function, it used gst_buffer_get_nvds_batch_meta() and I don’t think deepstream now has c++ wrapper.

My question is that since they use Glib::RefPtr <Gst::Buffer> in gstreamer c++ wrapper, is it possible to directly casting this back to GstBuffer pointer?

Has anyone have used this or have any idea about this?

Thanks in advance

Hi,
Please refer to

The sample plugin is compiled through g++. Please check if you can make custom plugin based on the sample.
