Internal data stream error when using gst_loopback

Dear Ricoh Theta V friends,

We got internal data stream error when using gst_loopback even a dummy /dev/video* is created and is assigned by v4l2loopback.
By following this nice tutorial, both ptpcam and gst_viewer works well.

But we stuck on gst_loopback, it outputs below error:

start, hit any key to stop
Error: Internal data stream error.

Seems like we are very close, one step to get it working, were wondering if any one got the same issue.

Our desktop testing environment is Ubuntu 18.04 LTS, with Linux 4.15.0-118-generic, x86-64
Camera is Theta V with the firmware 3.50.1
