OpenCV - getting the slider to update its position during video playback

Question

I\'ve picked up \'Learning OpenCV\' and have been trying some of the code examples/exercises. In this code snippet, I want to get the slider to update its position with each

Answer 1

OK I finally solved this problem of updating the slider and also if you want to move the slider the video will update there is no problem of picture freezing now

#include "stdafx.h"

#include
#include
#include

int g_slider_position = 0;
CvCapture* g_capture = NULL;
int count=0;              //initiate a global counter



void onTrackbarSlide( int pos )
{// if you are moving the slider for more than two frames then this loop will initiate      to
 // to update the video
    if(pos>count+2 || pos

ok now what i have done is that i have created a global counter which will be updated alongside with the frames

now when we use the slider with the mouse to a different position then in onTrackbarSlider routine the if loop will be initiated and it will set the video to the new position
