How to save result using yolo plugin on TX2

Hello,
Now I want to save the recognized video result using yolo plugin based on TX2 platform,do you have any suggestion for this ?

I have learned the test deepstream-test1.app code ,it’s using g_object_set(G_OBJECT(sink), “location”, “out_test1.mp4”, NULL) to save result.
