Can't run "ptpcam -R 0x101C" on ubuntu16.04LTS, Theta V FW:3.40.1

I tried to run “ptpcam -R 0x101c” but I got an error and could not start video recording with Theta V.

Sending generic request: reqCode=0x101c, params=[0x00000000,0x00000000,0x00000000,0x00000000,0x00000000]
PTP: Invalid Parameter
PTP: ERROR: response 0x201d

According to the past thread, it seems to work on Ubuntu 14.xx, but I want to use ROS Kinetic, so I can’t change the version down.

I hope you can somehow make it possible to record video.
Also, there are a number of other commands that can’t be executed for something else.
Is this an error for the same reason?

I’ve written a version of the elements that might be necessary for a smooth resolution.
I’ll keep adding to it as requested.

The version of each element

I’m Japanese, so it would be helpful if you could write in simple English, which is easy to translate.
