hi!

thanks for the answer, but that's not the thing i need. i need to output 2 different videostreams from one external i'm just programming (the kinect outputs one rgb and one depth video stream). but i'm not sure if the gem framework allows two gemstate outputs from one object.

greets matthias

Hello,

I am not sure if I got your question completely right, but you can put the pix_ output in a buffer: http://wiki.puredata.info/en/pix_buffer And read is as many times as you like. You can use an "t a b" to go though the buffer or fill it based on the frame rate, I found an example in the patch on this url: http://www.dazegraffiti.com/2010/08/pixfreeframe-1.html

Regards, Harrie

    is it possible to output 2 images (gem_states) from one pix_
    object?
    is there any example for something like this around?

    i'm working on an openni external in the moment that can
    output skeleton data and kinect video streams at the same
    time.
    it's working fine but i don't know how to output the depth and
    the rgb videostream at the same time.

hi,

did you finally found a way to output more than one pix image from a pix object ? i'm interessed in it too and also on adding severals pix_image input

there shouldn't be any problem outputting with outputting 2 separate states (holding 2 separate images) onto 2 separate outlets.

what are you struggling with?

hi!

you can find an example how to do two outputs from pix_ object in my pix_freenect external. http://www.matthiaskronlachner.com/wp-content/uploads/2011/11/pix_freenect_0...

i made an additional inlet and outlet for gemstate plus the methods that get called, 2 pixBlock and an additional GemState.

so the pieces of code that are interesting: constructor: m_depthinlet = inlet_new(this->x_obj, &this->x_obj->ob_pd, gensym("gem_state"), gensym("depth_state")); m_depthoutlet = outlet_new(this->x_obj, 0);

setupCallback: class_addmethod(classPtr, (t_method)(&pix_freenect::renderDepthCallback), gensym("depth_state"), A_GIMME, A_NULL);

-> renderDepthCallback() calls the rendering method for the second output -> renderDepth(int argc, t_atom*argv);

the tricky thing is how to deal with the pointers from GemState and how to get them out of argc arguments (at least for me it was...)

so if you are still interested have a look at the code and ask if questions rise.

hi, i've found some examples on how to input two separate states (pix_add, pix_diff, pix_multiply...) but none with 2 outlets for 2 different states, so where can I find an example with 2 state outlets ?

and what about more than 2 inlets or outlets for holding more than 2 images ?

sorry for these silly questions but i'm not a programmer in fact :-)

thanks
