cv2.videoCapture 仅返回“uri 中缺少端口"； [英] cv2.videoCapture only return "Port missing in uri"

问题描述

首先感谢您的关注.我正在尝试使用 opencv 和 ip 摄像头进行流式传输，但它只返回[tcp @ 000001d5fce13580] uri 中缺少端口".我已经在 VLC 上进行了测试，也用 JavaCV 进行了测试，并且在两者上都可以使用.我已经检查了 MPEG 并且没问题.有没有人经历过这个并且可以提供帮助?

我和:

• WIN10
• OpenCV 4.5.1

代码:

将 numpy 导入为 np导入 cv2def runCam():打印(cv2.getBuildInformation())video_src = "rtsp://admin:myPWCam@192.168.1.223:554/Streaming/channels/1/";帽 = cv2.VideoCapture(video_src, cv2.CAP_FFMPEG)为真:ret, frame = cap.read()尝试:cv2.resizeWindow('Stream IP Camera OpenCV', 120300, 800)cv2.imshow('Stream IP Camera OpenCV', frame)除了例外，例如:template = "发生了 {0} 类型的异常.参数:\n{1!r}"message = template.format(type(ex).__name__, ex.args)打印(消息)休息如果 cv2.waitKey(1) &0xFF == ord('q'):休息cap.release()cv2.destroyAllWindows()运行摄像头()

问题出在我的密码上，由于某种原因，当密码包含#"时，opencv 的 VideoCapture 会感到困惑.当我在 javacv 和 VLC 中测试它并且它工作时，我没有用另一个密码测试它并且浪费了很多时间:(但是现在我发现我更改了密码并且它已经工作了.我希望它可以帮助那些谁有同样的问题要注意特殊的密码字符.

First of all, thank you for your attention. I'm trying to stream with opencv and ip camera, but it only returns "[tcp @ 000001d5fce13580] Port missing in uri". I have already tested on VLC and also tested with JavaCV and it works on both. I already checked the MPEG and it's OK. Has anyone been through this and can help?

I am with:

• WIN10
• OpenCV 4.5.1

CODE:

import numpy as np
import cv2


def runCam():
    print(cv2.getBuildInformation())
    video_src = "rtsp://admin:myPWCam@192.168.1.223:554/Streaming/channels/1/"
    cap = cv2.VideoCapture(video_src, cv2.CAP_FFMPEG)

    while True:
        ret, frame = cap.read()
        try:
            cv2.resizeWindow('Stream IP Camera OpenCV', 120300, 800)
            cv2.imshow('Stream IP Camera OpenCV', frame)
        except Exception as ex:
            template = "An exception of type {0} occurred. Arguments:\n{1!r}"
            message = template.format(type(ex).__name__, ex.args)
            print(message)
            break

        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

    cap.release()
    cv2.destroyAllWindows()

The problem was with my password, for some reason opencv's VideoCapture gets confused when the password contains "#". As I tested it in javacv and VLC and it worked, I had not tested it with another password and wasted a lot of time with it :( But now that I found out I changed the password and it already worked. I hope it helps those who have the same problem to be aware of special password characters .
