Can't read bag file anymore



Since I updated Nuitrack 0.28 I can’t read .bag file anymore (using d415 camera)
I get “Critical error detected c0000374” whenever I try to set a path like I used to
(Something like Nuitrack::setConfigValue(“Realsense2Module.FileRecord”, “path”))
Does someone experience the same bug or something changed in the .config file?

Thank you


Hi Shogenn1,

  1. What license do you use?
  2. What version of RealSense SDK do you use?

Starting from Nuitrack v. 0.28.0, you can use Nuitrack with .bag files only with the activated trial license. Trial licenses can be generated in Nuitrack personal account:


Hi Olga,

  1. I use the trial license activated from personnal account
  2. The latest one 1.4.0

  1. What is your RealSense SDK version? It seems that you mentioned Nuitrack SDK version.
  2. Please send us the .bag file that cannot be read so we can check it. You can upload it to any cloud storage and send me the link in a private message or to

  1. I was using librealsense 2.20, I tried to update it to 2.24 but nothing changed
  2. I use the regular recording with the realsense viewer, I can send you one .bag file but I don’t see why It used to work perfectly fine in 0.27 and now it’s impossible, maybe I need the pro version?


No, Pro version is not required. Please record and send us a .bag file.
By the way, what is your OS? Is it 32-bit or 64-bit?



I have a similar issue. After update Nuitrack to 0.28 it failed to start; so I had to upgrade RealSense and OpenCV to 2.21 and 3.4.0 respectively. But the following problem comes when load from a .bag file: as soon as the user enter in the scene, the video stops and the console shows the message:

UVCVideoCapture::open ERROR: can’t find device
Can’t find video camera!
Can’t find Depth camera!
Create DepthProvider: Realsense2DepthProvider
LicenseNotAcquired exception (ExceptionType: 6)
LicenseNotAcquired exception (ExceptionType: 6)
LicenseNotAcquired exception (ExceptionType: 6)

I’m using a licenced Nuitrack Pro activated under version 0.27, and now I’m working with this system:

Ubuntu 18.04, amd64
librealsense2,librealsense2-dbg,librealsense2-dev,librealsense2-udev-rules,librealsense2-utils/bionic 2.21.0-0~realsense0.952
librealsense2-dkms/bionic,now 1.3.6-0ubuntu0 all

Thanks in advance for your help.


I did send you a .bag file
My OS is 64-bit
Thank you


Hi Raul,

Nuitrack Pro won’t work in this case. If you want to use Nuitrack with recorded videos, you should activate Nuitrack Trial (generate a trial key in your personal account).
