Delay to load and delayed stream

edit

Im running this code:

#include <iostream>
#include <sstream>
#include <ctime>
#include <string>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

using namespace cv;
using namespace std;

int main()
{
    //create matrix for storage
    Mat feed, feed2;

    //initialize capture
    VideoCapture cap, cap2;
    cap.open("http://192.168.1.128/videostream.asf?user=admin&pwd=");
    cap2.open("http://192.168.1.110/webcam.mjpeg");

    // check if we succeeded
    if (!cap.isOpened()){
        cerr << "Failed to open video capture" << std::endl;
        cout << "cannot open camera";
        return -1;
    }
    if (!cap2.isOpened()){
        cerr << "Failed to open video capture" << std::endl;
        cout << "cannot open camera";
        return -1;
    }

    //create window to show image
    namedWindow("VIDEO", 1); 

    //loop
    while (true){

        //copy webcam stream to image
        cap >> feed;
        cap2 >> feed2;

        resize(feed, feed, Size(1270, 700), 0, 0, INTER_CUBIC);
        resize(feed2, feed2, Size(320, 170), 0, 0, INTER_CUBIC);

        feed2.copyTo(feed(cv::Rect(874,463,feed2.cols, feed2.rows)));
        //small_image.copyTo(big_image(cv::Rect(x,y,small_image.cols, small_image.rows)));


        //webcamstream
        imshow("VIDEO", feed);

        //exit it key pressed
        if (waitKey(30) >= 0){
            break;
        }

        //delay33ms
        waitKey(10);
        //

}//main

I've got a Raspberry pi with a USB composite capturer running FFMPEG on server with the following setup:

/etc/ffserver.conf

Port 80
BindAddress 0.0.0.0
MaxClients 10
MaxBandwidth 50000
NoDaemon

<Feed webcam.ffm>
file /tmp/webcam.ffm
FileMaxSize 10M
</Feed>

<Stream webcam.mjpeg>
Feed webcam.ffm
#Format mpjpeg
Format avi
VideoSize 320x170
VideoBufferSize 5
VideoFrameRate 10
VideoBitRate 500
VideoQMin 1
VideoQMax 10
</Stream>

and the command:

ffserver -f /etc/ffserver.conf & ffmpeg -v verbose -r 10 -s 320x170 -f video4lilinux2 -i /dev/video0 http://localhost/webcam.ffm

When I use only one of the stream I can get delays or should I say I have a delay of 5 seconds which is acceptable, but when I have both stream I get a 20 seconds delay. I have looked around and there seam to be some bugs but looks like 2 years ago.

Is there any way to know what could be causing this? and how could I solve it? reducing the size buffer? I've noticed the the one of the stream from an IP camera come without delay
