Is creating a production node that inputs video texture from some arbitrary external source supported?

    This looks like a very interesting camera for near-distance work (15cm -

    It's a Time-Of-Flight (TOF) depth camera, with a 1280x720 visual camera
    and dual mics.
    Although it uses different tech, it should provide a point-cloud and
    depth image much like a Primesense, but with NO shadow in the depth image.
    Anybody have one yet? Mines been shipped, and there's a plugin to use
    the Intel SDK for it with vvvv which is how I will initially test it.
    Anyone know if thee cameras will be integrated into NITE and OpenNI? It
    would be nice, as using this camera WITH a Primesense camera would give
    excellent depth coverage.

    Hi all,
    I am a newbie. I got a Xtion Pro sensor recently. Will OpenNI Human
    detection and tracking work when we place the sensor close to the ceiling
    and looking down like an CCTV camera ?. If no, what are some good
    algorithms that I can implement to get it working.
    And How does the Human detection work in normal scenarios ?. Any good
    algorithm that I can learn from ?.

    Thanks Vahag, but this dataset has very few samples of ASL. It is a more
    general purpose dataset. I am now thinking of making a dataset of my own.:)

    I'm trying to use kinect and i got an "illegal instruction" answer as soon
    as try to run
    DAVWS2:x64-Debug generalh$ ./Sample-NiUserTracker
    Illegal instruction
    DAVWS2:x64-Debug generalh$ ./NiSkeletonBenchmark
    Reading config from: '../../Config/SamplesConfig.xml'
    Illegal instruction
    But it works like a charm for
    DAVWS2:x64-Debug generalh$ ./NiViewer
    DAVWS2:x64-Debug generalh$ ./Sample-NiSimpleRead
    Reading config from: '../../Config/SamplesConfig.xml'
    Frame 1 Middle point is: 556. FPS: 0.000000
    Frame 2 Middle point is: 561. FPS: 37.294646
    Frame 3 Middle point is: 560. FPS: 35.223670
    So my system is OSX 10.6.8 32bit
    In fact i'm trying to use an external jit.OpenNI from Diablodale in Max 6
    but our debug research brought us to a highlight a nite problem.
    We have other Max user for who this is working like a charm but for me....
    So if anyone could tell me how to track and find out my buggy bug...
    here is a crash log when trying to use jit.openni if this could help

    the problem you mentioned, that people had to move back and forth to
    calibrate is already the key point of your problem.
    This is due to the fact that to be able to recognize people in a scene,
    openNI needs some initial movement of the subjects.
    As soon as point clouds are classified as persons, the calibration can
    since you only started the recording AFTER the people were recognized, (I
    assume) they don't move, so are not recognized...
    if you had started recording from the beginning, this would have worked
    from the recorded files the same way as from the live video feed.
    i'm sorry i have no idea of how to help you with your problem except that
    you need to recapture those videos...
