Azure Kinect Examples do not work

[Prakash19921206]

Describe the bug
Python Examples do not execute. I have copied Azure Kinect SDK v1.2.0 to C:/Program Files/
Microsoft Azure Kinect Examples work

To Reproduce
Steps to reproduce the behavior:

1. clone the repository [open3d 0.9]
2. go to Open3d/examples/Python/ReconstructionSystem/sensors
3. py azure_kinect_mkv_reader.py --input "C:/Program Files/Azure Kinect SDK v1.2.0/tools/720.mkv"

Expected behavior
play the video/ record video/open kinect viewer

Environment (please complete the following information):

• OS: Windows 10 64bit
• Python version: 3.6.3
• Open3D version: 0.9
• Is this remote workstation?: no
• How did you install Open3D?: pip3

Additional context
output for azure_kinect_mkv_reader.py

No output path, only play mkv

Is there prebuilt c++ open3d libraries? or for now we have to build from source?

Thanks & Regards

This specific problem is due to an update of the API.
A quick fix is to change this line to vis.update_geometry([rgbd])

[Prakash19921206]

Ok Thanks
After replacing with vis.update_geometry(rgbd)
azure_kinect_viewer.py and azure_kinect_recorder.py examples worked.
but azure_kinect_mkv_reader.py is still not working below is the output

No output path, only play mkv

i have installed azure kinect SDK 1.2 and 1.3 in C:/Program Files/
also i have added dll files folder path in Environment Variable Path

Update: I noticed same error mentioned here and here

[Me817]

I use Open3D 0.10.0, Windows 10 and Azure Kinect SDK v1.2.0. I had the same error but after uninstall and reinstall the Azure Kinect SDK v1.2.0 and add the path C:\Program Files\Azure Kinect SDK v1.2.0\sdk\windows-desktop\amd64\release\bin to PATH in the environment variables and added the K4A_LIB_DIR = C:\Program Files\Azure Kinect SDK v1.2.0\sdk\windows-desktop\amd64\release\bin to the system variables it works perfectly for me

.

On Windows, the Open3D Kinect plugin will look for the Kinect K4A library located in the default installation paths:

https://github.com/intel-isl/Open3D/blob/3c6e66419a0f5669b27503f1e30dd4960b1aa4ba/cpp/open3d/io/sensor/azure_kinect/K4aPlugin.cpp#L76-L79

Currently, it supports 1.2.0 to 1.4.1. If the K4A library is not in the default location, you'll need to set the K4A_LIB_DIR environment variable to point to the directory containing the K4A's *.dll files.

I am still having this issue... System Variables set correctly, the reader runs perfectly when running from my base directory

C:\Users\bsieb

but as soon as I add an additional level to my directory it fails...

ex: C:\Users\bsieb\Desktop

I have tried everything possible... moving all of the files to the script directory, installing open3d with global options... nothing works unless it lives in my base user directory... any help would be appreciated, I would love to be able to wrap this into a exe for other team members if it would work.

UPDATE:

this is in a python environment:

python ( I've tried 3.7.7,3.7.8, and 3.8.5)
o3d (I've tried 0.10.0.0. and 0.12.0.0)
Windows 10
