[Andre Silva]

Hi Friket, are you still getting the video0 errors when running the application ?

Regards,
Andre

Dear Andre,

I checked the software, it look for Up.mp4 under /home/gesture directory. I have copied it and now the it is running, but the problem is I can only see the video is playing. Neither I see webcam output, nor gesture recognition works. I use my webcam normally at /dev/video0 and I can use it with my OpenCv applications directly.

Thanks,
Fikret

Dear Andre,

When I run gesture demo, I get the following console output now;

Now, the application is running, but I can only see black screen on the monitor. There is an error message as seen above, but I didn't have time to check from the software. Do you have an idea about the error message?

I have one more question: Actually I am not interested in OpenGL, because we want to perform image processing. So, OpenCL will be more suitable for us, but I couldn't find any examples other than hello world for IMX.6. I searched if we can use OpenCV OCL module on IMX.6, but I learned that it is not possible. So, if you know a way to use GPU for image processing, please recommend a way to me (such as an example using both OpenCV and OpenCL)

Thanks&Best Regards,
Fikret

Hi Friket,

I was about to ask you about the galcore module, as I always use it as built-in I thought you were using this way too. I´m glad it worked.

About the gesture recognition demo, what is going on ? what kind of errors are you getting ?

Regards,
andre

Hi again,

Thank you for your answers. I have solved the problems by starting the GPU module

$ modprobe galcore

and with the display setting
$ export DISPLAY=:0.0

By this way I can run the X11 samples on Yocto, but I have still problems with Andre's gesture recognition example :)

I can not compile anything with softfp, because the compiler can not find stubs_soft.h. In Yocto, there is only stubs.h and stubs_hard.h

Best Regards,
Fikret

Hi Guys,

I will need to check that. One question: if you let it as softfp, does it work ?

Regards,
Andre

Andre, do you have any clue?
