opencv and c++ visual studio 2012 -

i have code work good.

when video length less 1 minute , video size 165 kb when change video other length 2 minute , size 15 mb or 1 same length size 5 mb show me

project has stop working

this code

also when o comment

  ( int = 0 ; < samplesnum ; i++ ) {       x = ( int ) condens -> flsamples [ ] [ 0 ] ;      y = ( int ) condens -> flsamples [ ] [ 1 ] ;       if ( x >= 0 && x <= 640 && y >= 0 && y <= 480 ) { //      getpixel ( hsv , x , y , &h , &s , & v ) ;      if ( h <= 19 && s >= 48 ) { // //h<=19 s>=48       cvcircle ( image , cvpoint ( x , y ) , 4 , cv_rgb ( 255 , 0 , 0 ) , 1 ) ;      condens -> flconfidence [ ] = 1.0 ;      }      else {      condens -> flconfidence [ ] = 0.0 ;      }      }      else {      condens -> flconfidence [ ] = 0.0 ;      }      }  

program work without idea of track object

i have windows 8

please comment if u dont understand thing

i think problem related declaration of iplimage *frame inside for loop. when size of video length increases then, memory gets full. because continuously creating new frames inside for loop without freeing memory allocated them.

you should declare iplimage *frame outside for loop , release memory allocated outside for loop.

advice: not use old c-standards of opencv. use new c++ standards have declare image mat image. then, don't need think freeing memory because stuff itself.
