How to generate a picture file while using Gst-nvsegvisual plugin?

I am using the the Gst-nvsegvisual – deepstsream segmentation plugin to create an application.

In this application, instead display the segmentation picture on the window, I want to save that as a file. I try to set:

sink = gst_element_factory_make (“filesink”, “file-sink”);
nvsegvisual = gst_element_factory_make (“nvsegvisual”, “nvsegvisual”);

but I can not get gst_element_link_many() call work, it gives the error:
“Elements could not be linked: 1. Exiting”

I think that nvsegvisual caused the function call failed.

Can some one let me how to generate the picture file?

Thanks
Jimmy

Can you refer to the sample of segmentaion? It is in /opt/nvidia/deepstream/deepstream-5.0/sources/apps/sample_apps/deepstream-segmentation-test.

solved the problem by using the following pipeline:

H264/JPEG–>decoder–>tee -->| – (batch size) ------>|–>streammux–> nvinfer–> nvsegvisual → vosd → |—> encode —>filesink (save the output in local dir)

Thanks
