我刚刚在 OSX 10.11.5 上设置了libfreenect2，我可以成功运行显示 RGB/IR/深度流的 Protonect 演示，但我也想使用 OpenNI/NITE 进行骨架跟踪。

我已经按照 OpenNI 的 repo 的 README 文件中的说明进行操作，但是当我尝试运行 NiViewer 时，我得到了这个：

NiViewer 
openDevice failed:
    DeviceOpen using default: no devices found

Press any key to continue . . .

我目前正在 github 上处理 libfreenect2 问题，并在此处记录我正在尝试的内容和结果。任何提示/提示都是有帮助的。

在 OSX 上使用 Kinect v2 使用 libfreenect2 设置和测试 OpenNI/NITE 的最简单方法是什么？

原来我使用的是 NiTE 1.5，而我应该一直使用 NiTE2.2，我只是简单地libfreenect2-openni2.0.dylib从复制libfreenect2/build/lib到NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers/然后运行SimpleUserTracker示例并且它有效！

仍然有一个问题：仅打印到控制台的示例运行，但打开窗口并渲染的示例不起作用。没有渲染窗口，好像该线程以某种方式被阻塞。那是我使用集成英特尔 GPU 的时候。如果我使用离散的 nVidia GPU，应用程序会崩溃：

我怎样才能解决这个问题？

作为参考，这里有上述注释作为回答。这就是我使用 libfreenect2 和它的 OpenNI2 驱动程序获得 OpenNI2/NITE2.2 骨架跟踪所做的。我有：

  1. 通过自制软件编译安装的 OpenNI2 并根据github repo 的自述文件说明编译 libfreenect2 并支持 OpenNI2
  2. 下载了 NITE2.2（替换了我之前误用的 Nite1.5）
  3. 将 libfreenect2 OpenNI2 驱动程序 (ibfreenect2/build/lib/libfreenect2-openni2.0.dylib)Drivers复制到我需要运行 NITE2 的文件夹中（例如NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers）。

通过在 OpenNI.ini 中将日志级别设置为详细，我发现路径错误：

[Log]
; 0 - Verbose; 1 - Info; 2 - Warning; 3 - Error. Default - None
Verbosity=0
LogToConsole=1
LogToFile=1

[Device]
;Override=""

[Drivers]
; Location of the drivers specified by a relative path based on OpenNI's shared library or an absolute path.
; Path separator "/" can be used to be portable for any platforms.
; Default - OpenNI2/Drivers
Repository=OpenNI2/Drivers

Symon Kaliski 遵循笔记并使用OpenFrameworks在 OSX 上编写了出色的 Kinect 2，并带有骨架跟踪帖子，请务必查看！

此外，一旦 libfreenect2 使用 openni2 支持编译，它甚至可以在处理中使用，只需将 libfreenect2-openni2.0.dylib 放入/Documents/Processing3/libraries/SimpleOpenNI/library/osx/OpenNI2（在 OSX 上）：
