Hi,
First of all, thanks dear Zach for this wonderful C++ interface.
I’m an artist trying to escape Actionscript, in order to use an ‘open framework’ platform. To try my first step, I want to move this application I did in Flash to OF: http://82.223.148.78/im/regenerativo/marco.htm . Excuse me for my ignorance — I have a couple of stupid questions to do. As you see, I deal with dynamic video permutation. To do that I took advantage of Actionscript NetStream Class (duration), Array Methods and SetInterval function in order to manage space and time. My question is: ¿what kind of class could I use to replace the well known Actionscript pop/shift/etc. array methods? How could I do to manage Time same way I did with SetInterval? I also got problems to Scale video to bigger size than the source file.

Thanks, and sorry for my ignorance,

hi - sorry for the delay -

can we take you questions one at a time:

a) how to scale video:

you should be able to draw using x,y,w,h:

  
  
myvideo.draw(x,y,w,h);

b) shift / pop, etc:

since I am not so familiar with flash, can you explain in more detail what you mean?

thanks!
take care,
zach

Thanks for your answer. I mean,

  1. I need some Class/Methods to deal with Array or Matrix. For example, with AS I have the Array Class, and with it the pop/shif/splice methods to extract the elements from this array. I also have the properthy “array.length” to know how many alements it has. Etc. I use it to deal with video files name. Is there something similar in CC++? How can I extract the last/first or middle element from an array? How could I know how many elements remains in an array? (Sorry for my ignorance)
  2. To call a Function each X time, As use this sentence:

setInterval(myFunction, Time);

This way, for example, I can order a function to be executed at X time.
All of that allow me to execute, for example, a series of video files in this way

myVideos = [“a.mov”, “b.mov”, “c.mov”]
myPlayer.play(myVideos.pop()); // “pop” remove the last element from an Array

//then –for example
duration = myPlayer.duration //duration of the current shot

setInterval (rePlayFunction, duration);

function rePlayFunction(){

myPlayer.play(myVideos.pop()); // “pop” remove the last elemento form an Array
//etc.
}

Therefore, I would like to know the way to deal with Arrays, and also to manage time and function same way than SetInterval allows
Thanks,
i

ivanmarino –

In c++, an “Array” can only hold data in static memory locations and this length, cannot be changed once you create the array. You are also limited to number variable types and characters.

http://www.cplusplus.com/doc/tutorial/arrays.html

What you need are Vectors and Deques, which are two additional types of memory handlers. A Vector type allows pushing and popping from the end of the array, and a Deque allows pushing and popping from the begging and and the end of the array. Also, you may store any type of object or datatypes in these two types.

Deque: http://www.cplusplus.com/reference/stl/deque/
Vector: http://www.cplusplus.com/reference/stl/vector/

Good luck! Also, Google as much as possible! :slight_smile:
