Do you see the error with `Protonect`?

Um, it might be the issue related graphics, but I'm afraid that I don't have a workaround right now. It's worth trying to see which packet processor triggers this; OpenGLPacketPipeline,...

@LucasSubli You can switch to CPU or OpenGL packet processor. See: - https://github.com/r9y9/pylibfreenect2/blob/master/examples/multiframe_listener.py#L11-L21 - http://r9y9.github.io/pylibfreenect2/latest/api.html#packet-pipelines

Well, since I don't have Kinect v2 anymore, it's hard to say what is the real cause of this. Could anybody confirm whether the issue comes from pylibfreenect2 or libfreenect2?...

@tokyokuma Thank you very much! So there should be something wrong with OpenCL setup. I used OpenCL backend because it was the fastest backend for me, but I changed example...

Looks like there are missing DLLs not in `PATH` and it's not specific problem to pylibfreenect2. While googling I found there are many similar reports. e.g., https://github.com/skvark/opencv-python/issues/36.

> Alternatively I believe you could append the path to the dlls to your path variable, Yes. See also: https://github.com/r9y9/pylibfreenect2/blob/78b8748ea356d8ed61d862e24e8eab934d94d6e3/appveyor.yml#L36-L41.

Assuming you are talking about reading depth values from a pre-recorded depth sequence, I think you can just use opencv’s VideoCapture.

That depends on how you saved depth data. For example, assuming the maximum depth in milli meter was 4500, If you scaled the depth values by 255/4500 and saved it...

Because I didn't use the functionalities until now. Pull requests are welcome.
