issue compiling ofxKinect in armv7l(PandaboardES)

[kalwalt]

i can't compile successfully the addon example . Simply i get a libfreenect linking error:

normally this shouldn't happens with linux. i have libusb-1.0 installed . and added the C_FLAGS

PROJECT_CFLAGS += -I/home/walter/OF-develop-raspberrypi/openFrameworks/addons/ofxKinect/libs/libfreenect PROJECT_CFLAGS += -I/usr/include/libusb-1.0

LD_FLAGS

PROJECT_LDFLAGS += -L/home/walter/OF-develop-raspberrypi/openFrameworks/addons/ofxKinect/libs/libfreenect/libfreenect.h PROJECT_LDFLAGS += -lusb-1.0

but these not solve at all the problem.

normally it is not needed to add the C_FLAGS for libfreenect but without it i got errors.

i'm using the develop-raspberrypi branch.

[jvcleave]

I would try using libfreenect from apt-get and link it in via PROJECT_LDFLAGS += -lusb-1.0 -lfreenect

you can also try the libfreenect demos to make sure the device is working (powered usb hubs are helpful)

[kalwalt]

Thanks for the suggestion @jvcleave . i will try in the next days, after Christmas!

[kalwalt]

Made some other tests. Used the libfreenect lib installed from apt-get. But it failed. Also demos didn't worked. Instead i downloaded the libfreenect from https://github.com/OpenKinect/libfreenect i build it succesfully and also demos works very well with my Kinect! wow! So i copyed and pasted the static libfreenect.a in a new folder in the ofxKinect ../../openFrameworks/addons/ofxKinect/libs/libfreenect/lib/linuxarmv7l but i got errors with usb_libusb10.c.o not matching in libfreenect.a(usb_libusb10.c) . so i think i have to use the newer libusb version. i don't see any other solution that to fork ofxKinect and to develop an armv7l version...

We might want to move this discussion over to ofxKinect on github as it doesn't deal with the core of oF? On Dec 26, 2012 12:47 PM, "Walter Perdan" notifications@github.com wrote:

[jvcleave]

@kalwalt I would try to use the headers/lib you compiled yourself as well as libusb that is installed on your system

@danthemellowman yeah - this is one of those weird issues - it probably belongs in ofxKinect but it is not an easy move and will get more attention here as a lot of us want to get it working with ARM. Maybe @kalwalt can write a wiki page or something once he gets through it (I think you are close!)

[kalwalt]

Hi to all! today i'm luky, I managed to compile ofxKinect !! the only way to link libusb-1.0.a was to copy and paste it from my sytem in the same folder where i have libfreenect.a ( the one that i compiled by myself) then it compiled succesfully. But beyond the initial enthusiasm, I have no picture on the screen. I have a single black screen. I think it's due to ofxOpenCv. I have a similar problem reported here: https://github.com/openFrameworks-RaspberryPi/openFrameworks/issues/18 this will be resolved when I have a solution for ofxOpenCv.

It is strange, however, that I had to copy the libraries to make them to link. perhaps the system makefile can not find it? I installed (with synaptic) libusb-1.0.a in / usr / arm-linux-gnueabihf . Maybe this is the reason.

It is also necessary to examine whether: the header and source libfreenect that I changed are of a different version or not. libfreenect.a if I changed differs from that obtained by installing from synaptic. I have to do other tests and investigations short, and surely I will open a wiki as suggested by @jvcleave and some examples( maybe a very simple one with only one screen)

[kalwalt]

now i have video stream from kinect.draw() and kinect.drawDepth() but it'is glitcy, blocky and weird . probably issue related to https://github.com/openFrameworks-RaspberryPi/openFrameworks/issues/21 or what?

[danzeeeman]

I would like to see for myself. I'm getting on a flight back to NYC today (where my kinect is) can you throw up a repo with the code and libs you compiled? Maybe fork ofxKinect and put it there?

Thanks,

Dan

[kalwalt]

yes of course! i have already the ofxKinect fork : https://github.com/kalwalt/ofxKinect/tree/develop-Pandaboard-linuxarmv7l but i have to upload the example and other code , i think i will do in the next hours. i will post when it will be done .

[kalwalt]

ok @danthemellowman you can find the latest on my repo , there is a new example that works with the issue that i explained, let me know if you find problems or what else.

[jvcleave]

@kalwalt I don't think your video issue is related to #21 ssue as ofxKinect won't be using GStreamer (all the video/depth functionality comes from libfreenect)

Are you using a powered USB hub? That may help if it is a power issue.

[jvcleave]

I would also try building an example without ofxOpenCv to rule out CPU issues. Maybe just init the kinect and try to draw the video

[kalwalt]

I don't think your video issue is related to #21 ssue as ofxKinect won't be using GStreamer (all the video/depth functionality comes from libfreenect)

yes @jvcleave , you are right, looking at the code i can see it.

Are you using a powered USB hub? That may help if it is a power issue.

yes, i'm using it.

I would also try building an example without ofxOpenCv to rule out CPU issues. Maybe just init the kinect and try to draw the video

i have done this in my repo.https://github.com/kalwalt/ofxKinect/tree/develop-Pandaboard-linuxarmv7l/ofxKinect-linuxarmv7l-Example but i have the same issue. Running the libfreenect examples https://github.com/OpenKinect/libfreenect/tree/master/examples instead i have not this issue

[danzeeeman]

you can try initing ofxKinect with init(false, false) to disable the video output and just grab the RAW depth pixels? I can't find my power supply for my kinect so I can't test with my pi.

[kalwalt]

@danthemellowman Tried with init(false,false). i have the same issue glitchy. The difference is that now he does it with the depth map. with kinect.init() instead i have a video glitchy and depthmap static like single frame.

but it's strange after a period of time works as should works with a regular flow of frames! and then became glitchy for a certain period of time... why this?

It seems as if it does not happen an efficient flow of data.

[danzeeeman]

I'm seeing the same glitchy video using the videograbber. I put up a video in Issue #95. I'm playing around trying to find the cause.

i found this article about libfreenct performance on Pandaboard: https://groups.google.com/forum/?fromgroups=#!topic/openkinect/dfPLgD6FjUY

so i tried as suggested FREENECT_DEPTH_11BIT_PACKED in void ofxKinect::threadedFunction()

freenect_frame_mode depthMode = freenect_find_depth_mode(FREENECT_RESOLUTION_MEDIUM, bUseRegistration?FREENECT_DEPTH_REGISTERED:FREENECT_DEPTH_MM) to freenect_frame_mode depthMode = freenect_find_depth_mode(FREENECT_RESOLUTION_MEDIUM, bUseRegistration?FREENECT_DEPTH_REGISTERED:FREENECT_DEPTH_11BIT_PACKED)

but got seg fault .i run it in gdb mode but after Ubuntu freeze( it's happens sometimes it is a known issue) I will post it after. but as i remeber it involve threading.

using instead FREENECT_DEPTH_11BIT or FREENECT_DEPTH_10BIT i have not seg fault ,it help a little little bit but the video depth is still glitchy. so probably the problem is in how the pixels are handled?

@danthemellowman but with my pandaboard the videoGrabber works good i havent that glitchy issue.

[kalwalt]
