     So you're saying that OpenNI Tracker works fine on your computer but the test application crashed? Did you try it twice as I asked?

    I actually got a similar error just now after installing a High Sierra security updated 2020-3.

    But the test app worked after I did the following:

    1) Unplug Kinect USB connector
    2) Disconnect power cable from Kinect
    3) Reboot computer
    3) Connect power cable to Kinect
    4) Plug in Kinect USB connector

    Could you please try that? I'd like to know that it actually works.

    @Demetri79 -- what about you?

    Best Wishes,
    Mark



  • Mark.

    1. Yes, OpenNI Tracker works well with the tutorials you supplied. Takes a couple of minutes max for the image to show up, but it always does appear.

    2. I did as you suggested above and then ran it twice with the same result as above: ... "line 5: 704 Illegal instruction: 4 "$SCRIPTPATH/SimpleViewer"" Test #2 has a small variation "line 5: 734 Illegal instruction..."

  • @mark

    the test application did not open a viewer window after 10 tries. And I did the boot up process you described exactly. Do you want all 10 terminal reports? I'm just providing 1 for now since they all looked essentially the same except for the numbers next to: INFO, VERBOSE, and LINE 5.. were different on each attempt. I even tried the closest point viewer test 4 times. no viewer window.

    ALSO: today before I before i performed the simple viewer test.. first boot up of the day the kinect was recognized and output depth and skeleton data in an otherwise blank session containing only Open NI .0.9.2 and skeleton decoder. I let it run for 30 min with no problems. so then i shut the test patch and opened my patch which  has the Open NI and skeleton decode already wired in and it was also recognized and passed image and data for about 2min until the image and data started glitching and freezing.. then froze completely. So I performed the complete shutdown booted back up and nothing.. could not get it working again after 10 shutdowns. So I switched to Open NI 0.9.6 .. could not get that working after 10 attempts. Then I performed the simple viewer test as mentioned above over 10 times.


    there is no hardware or software issues with my kinect and I have varified this by connecting it to another computer running all the same versions of software and plugs: macbook pro 2013, mac os 10.13.6, isz 3.0.7.. and tested all 3 versions of Open NI and the kinect was recognized and worked flawlessly every time conected. i tested it 15 times and let it run for a couple hours.. no problems

  • @demetri79 and @jfg 

    So if I understand things correctly, the the only two people having problems are both on an older Mac Pro (aka "cheese grater" model).

    @Demetri79 :

    First, I don't think you have to try things ten times. Three is enough. If it doesn't work after three attempts, then it's not working.

    That said: you have a  Mac Pro 2012 5,1 running High Sierra 10.13.6, yes?

    What processors/how many cores? (Can you please put your hardware configs in your signature line like @jfg? That save me having to go through this whole thread trying to find this information. Thanks. ;-) )

    When you run the same plugins on your laptop, everything is fine, right?

    Also, there was a recent update to High Sierra that broke, among other 32-bit apps, Abelton Live. Now, Isadora and OpenNI Tracker are all 64 bit, but I wonder if a software update could have caused your Mac Pro to stop recognizing the Kinect reliably. (Because -- based on your previous posts -- it worked well on the Mac Pro previously, right?)

    @jfg :

    You are also using a Mac Pro 2012 (3,33 GHz 6-Core Intel Xeon) running Mojave 10.14.6, yes?

    When you run the same plugins on your laptop, everything is fine, right?

    @Demetri79 & @jfg 

    My fear here is that the library "libusb" which handles communication to the Kinect is failing, especially since you both mention the PCI USB 3 cards you have installed. There is an NI Mate thread that details a user having problems with macOS Sierra on a Mac Pro that sounds really similar. (When I wrote this, the original NI Mate post wouldn't open; but you can read Google's cached version.) In that thread they instruct the user to try a different libusb included with NI Mate, but I don't think it ever solve the problem.

    In the end, I may have you to install the homebrew package manager and compile libusb on your machine. When you do this, the library is compiled with specifically for the hardware and operating system on your computer. I don't know if this will solve the problem or not... but right now, I don't know what else to tell you two.

    If you are willing to take the time to try compiling your own libusb with homebrew, let me know and I'll post the instructions.

    Best Wishes,
    Mark



  • @juriaan (and all -- please read I want an opinion)

    When I use the 'capture mode' input of the plugin and set it to Color I also receive the depth image. What I expected to happen is that I only get the color image and that the depth image was disabled / not active (So a red line instead of a green line to the projector)

    I realize now why this is happening; it was actually by design. If you set the 'body tracking' to off, you will only get the color image. If 'body tracking' is on, then the plugin always enables the depth stream because you are telling the plugin you want to track bodies.

    Do people find this confusing? Should I change it so that, if the mode is set to 'color', body/skeleton tracking is simply disabled?

    Best Wishes,
    Mark



  • @juriaan said:

    Nope, I didn't save the file. Will test that out later tonight when I have some spare time.

    I have verified that if you have not saved the file, the current version of the plugin will not save the recording. I have fixed this for the next release.

    Best Wishes,
    Mark

  • @jfg said:

    OK. But it helps if you answer all my questions, so I'll ask them again:

    1) From what you say, I assume that the answer to "When you run the same plugins on your laptop, everything is fine, right?" is NO. Is that correct?

    2) But what about "You are also using a Mac Pro 2012 (3,33 GHz 6-Core Intel Xeon) running Mojave 10.14.6, yes?" Is that true or not?

    3) Did you try the test application in the kinect-test-macos.zip file I posted above? Can you follow the instructions there and give me the output of the Terminal window please?

    Best Wishes,
    Mark



  • @mark

    First I use the Xtion and not a kinect.

    All is running correct with openNI 0.9.2 on both computer Mac Pro 2012(3,33 GHz 6-Core Intel Xeon) and MacBookPro 2015 (2,8 GHz Intel Core i7) both with Mojave.

    On both computer I get the depth picture but no body tracking with 0.9.5 and 0.9.6

     unfortunately it exceeds my ability

    Thank you. OK, I knew you were using the Xtion. My partner may have one here... but at the moment we cannot find it. If we find it, then it will of course help me to figure out why you cannot track.

    It's good to know you get the the depth image. That means your problem is different from @Demetri79.  If you see the depth image, then it is not libusb and you do not need to try homebrew anyway. You also don't need to try the test application if you see a depth image.

    But wait: did we make a custom masquerade.txt file for you that is different than the default? What does it say? Can you .zip it and post it here?

    I will continue to seek answers for your issue.

    Best Wishes,
    Mark



  • @mark said:

     you don't. I used the normal masquerade.txt and it works with 0.9.2

    masquerade.txt(0.9.2).zip

    masquerade.txt(0.9.6).zip

    I have also tried to use the masquerade.txt from 0.9.2 in 0.9.6 but without success. Same result.

    thanks a lot

  • @jfg

    Try using this masquerade file (Note: for macOS only). It's a little bit of a guess... but maybe it helps.

    masquerade.txt.zip

  • @mark

    Dear Mark,

    you are sooooo good. It works on both computer. On the MacBook Pro (USB 3.0) and on the MacPro (USB 2.0). 


    With USB 3.0 on the MacPro I have the same problem as Demetri79 but it is not important because it works with 2.0.

    Another strange difference between MacBookPro and MacPro (or between USB 2 and 3) is the color video output: 

    - On the MacPro I get the video with the same little delay as the depth video.

    - On the MacBookPro (USB 3.0) the video color picture is frozen on the first picture also if I switch the capture mode on "color"

    On both computer the capture mode set on "color" show both picture (depth and color)


    I find it a little bit confusing because there is also "both".

    thanks a lot

    best

    Jean-François



  • More fodder for the mill... MBP 2012, 10.13.6 = simple viewer, as before, not working. You have the script error above. Thought I'd try the same process with iMac (Retina 5K, 27-inch, Late 2014) w

    (AMD Radeon R9 M295X 4096 MB) 10.13.6 and simple viewer works, but with lots of faults in the terminal.  - John (tried adding terminal info, but don't see the file I attached-sorry)

     Someone any advise about this?



  • @mark

    works still well. On the MacPro (USB 2.0) if I go out of the picture it takes 5-10 s to track the body and get the skeleton and sometime the skeleton get lost and I haven't find why it is coming back (could be 30 s) or not.

    I think not so important because all the new computer have USB 3.0. I haven't these problems on the MacBookPro (USB 3.0)

    record and play work well.

    thanks

    Regarding your question about the color mode. 

    It seems that we have 2 inputs

    1. Capture mode
    2. output depth

    Our help file of the capture mode tell us that we can use the capture mode to tell or we wish to capture the depth / color and send it to the desired output. 

    Output depth overrides this behavoir and basically makes it send out a depth image while you said against the Capture mode that you only want a Color mode for instance. 

    I personally wouldn't disable tracking when you set it to 'Color', that is where the Body tracking parameters are for. I would be fan if we can just disable the depth-video output if we only tell Izzy that we wish to capture color. (Internally you can still fetch the depth map for the inner workings of the plugin, just dont send it out to the output of the plugin so that the video signal is cut)
