我正在使用一个现成的QT创建者代码(declarative-camera)来开发一个apk,在这个代码中,qt访问计算机的网络摄像头,我试图做一些更改,以便能够访问远程摄像头。
问题:如何使这个远程连接工作?它是一个ip摄像机,我连接到无线网络
注:QML代码
下面是一段代码:

states: [
    State {
        name: "PhotoCapture"
        StateChangeScript {
            script: {
                camera.captureMode = Camera.CaptureStillImage
                camera.start()
            }
        }
    },
    State {
        name: "PhotoPreview"
    },
    State {
        name: "VideoCapture"
        StateChangeScript {
            script: {
                camera.captureMode = Camera.CaptureVideo
                camera.start()
            }
        }
    },
    State {
        name: "VideoPreview"
        StateChangeScript {
            script: {
                camera.stop()
            }
        }
    }
]

Timer {
    interval: 200
    running: true
    repeat: true
    onTriggered:  {
        image1.cache =false;
        image1.source = "rtsp://admin:@192.168.1.10:554/h264/ch0/main/av_stream";
    }
}

Camera {
    id: camera
    captureMode: Camera.CaptureStillImage

    imageCapture {
        onImageCaptured: {
            photoPreview.source = preview
            stillControls.previewAvailable = true
            cameraUI.state = "PhotoPreview"
        }
    }

下面是一个完整的代码尝试使这个连接:

import QtQuick 2.0
import QtMultimedia 5.4

Rectangle {
    id : cameraUI

    width: 800
    height: 480

    color: "black"
    state: "PhotoCapture"

    states: [
        State {
            name: "PhotoCapture"
            StateChangeScript {
                script: {
                    camera.captureMode = Camera.CaptureStillImage
                    camera.start()
                }
            }
        },
        State {
            name: "PhotoPreview"
        },
        State {
            name: "VideoCapture"
            StateChangeScript {
                script: {
                    camera.captureMode = Camera.CaptureVideo
                    camera.start()
                }
            }
        },
        State {
            name: "VideoPreview"
            StateChangeScript {
                script: {

             resolution: "640x480"
             frameRate: 30
        }
    }

    PhotoPreview {
        id : photoPreview
        anchors.fill : parent
        onClosed: cameraUI.state = "PhotoCapture"
        visible: cameraUI.state == "PhotoPreview"
        focus: visible
    }

    VideoPreview {
        id : videoPreview
        anchors.fill : parent
        onClosed: cameraUI.state = "VideoCapture"
        visible: cameraUI.state == "VideoPreview"
        focus: visible

        //don't load recorded video if preview is invisible
        source: visible ? camera.videoRecorder.actualLocation : ""
    }

    VideoOutput {
        id: viewfinder
        visible: cameraUI.state == "PhotoCapture" || cameraUI.state == "VideoCapture"

        x: 0
        y: 0
        width: parent.width - stillControls.buttonsPanelWidth
        height: parent.height

        source: camera
        autoOrientation: true
    }

    PhotoCaptureControls {
        id: stillControls
        anchors.fill: parent
        camera: camera
        visible: cameraUI.state == "PhotoCapture"

你可以在python上使用opencv来连接你的远程摄像头,opencv有一个函数(videocapture),可以解决你的问题
