[OSC_dev] addressing issue in openframeworks

hello all

i am pedro soler and i am new to the list. i am currently working in
Ecuador with the artist Daniela Moreno Wray on an interactive installation
called Transmestizx.

a collaborator created a software for displaying video on a raspberry pi
that is controlled from Pure Data via OSC.

the software has 2 layers of video works well but we need to add a third
layer or channel and this breaks the OSC addressing - or rather OSC still
considers there are only 2 layers.

i cant work out (and the collaborator has disappeared!) where in the code
it is specified that there are only 2 channels or mediaframes - it looks
dynamic to me !

the code is here http://codepaste.net/pyd8k7
the third layer/mediaframe has been added in line 55 and line 161 and it
draws fine, just cant work out how to modify the code to address the 3
layers !!!

any help would be highly appreciated

many thanks

pedro

Take a look at line 300 or so...
I'm not a C++ programmer, but that looks like your problem to me.

This code -

int mediaIndex = 0;

// Select the media frame.
if(requestMediaFrameChannel == "ch1"){
ofLog(OF_LOG_NOTICE, "__Channel 1 Selected");
mediaIndex = 0;

}if(requestMediaFrameChannel == "ch2"){
ofLog(OF_LOG_NOTICE, "__Channel 2 Selected");
mediaIndex = 1;

}else{
mediaIndex = 0;
}

sets mediaIndex to 0 if it's not "ch1" or "ch2".
