This code is reached if upstream uses the proposed pool. To demonstrate this
you can run:
Copy Path (not using the pool):
$ GST_DEBUG="GST_PERFORMANCE:5" gst-launch-1.0 videotestsrc ! identity
drop-allocation=1 ! waylandsink
...
0:00:01.851560175 15888 0x2178450 DEBUG GST_PERFORMANCE
video-frame.c:372:gst_video_frame_copy_plane: copy plane 0, w:1280 h:240
Zero-Copy:
GST_DEBUG="GST_PERFORMANCE:5" gst-launch-1.0 videotestsrc ! identity
drop-allocation=0 ! waylandsink
...
0:00:02.584972806 15987 0xc0c050 LOG waylandsink
