Open3d: Azure Kinect Examples do not work

[Prakash19921206]

Describe the bug
Python Examples do not execute. I have copied Azure Kinect SDK v1.2.0to 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.pyexamples worked.
but azure_kinect_mkv_reader.pyis 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 FilesAzure 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 FilesAzure 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.
