我试图从IP摄像头显示视频输入,得到以下错误
warning: Could not find codec parameters
(../../modules/highgui/src/cap_ffmpeg_impl.hpp:540)
这是相同的代码.
#include <stdio.h>
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main(int, char**)
{
VideoCapture vcap;
Mat image;
// This works on a D-Link CDS-932L
const string videoStreamAddress = "http://admin:admin123@172.41.20.55:80/? action=stream?dummy=param.mjpg";//From mjpeg streamer
//const string videoStreamAddress = "http://192.168.1.13:8080/videofeed? dummy=param.mjpg"; // Streaming from android using ip-cam
//open the video stream and make sure it's opened
if(!vcap.open(videoStreamAddress)) {
cout << "Error opening video stream or file" << std::endl;
return -1;
