win10 cannot read rtsp

[TangShuancheng]

Unable to read rtsp on win10 environment。

Current environment： gocv version: 0.23.0 opencv lib version: 4.3.0

The current rtsp stream can be opened using VLC，can't open through OpenVideoCapture。 Code show as below：

Error message: Error opening capture device: Error opening file

Try using VideoCaptureFile directly instead of OpenVideoCapture

[golubaca]

Also, your password contains @ character. In url string,@ is delimiter which separates auth information and url. It can throw an error sometimes if url is not parsed correctly.

@golubaca Both VideoCaptureFile and OpenVideoCapture have been tried, both have the same problem. In addition, I don't use rtsp url here, directly using local MP4 or avi is the same error message, but this program is passed under macOS.

[golubaca]

Hmm, I can't reproduce this error. Only time I got this error is when url to the file is wrong.

[TangShuancheng]

@golubaca You can look at the storage path of my current resources and the path written in the program. Is there anything you should pay attention to?Are there any special requirements on win10？

I got the video successfully by VideoCapture Need to load opencv_videoio_ffmpeg450_64.dll

I come across the same problem as yours，the problem is： Error opening video capture device: rtsp://admin:[email protected] My computer system is win7 How did you solve this problem? @deadprogram @golubaca @TangShuancheng @zxysilent @drnic

[golubaca]

Is the url provided your url from code? If so, this is probably not full path to rtsp stream.

Need to load opencv_videoio_ffmpeg450_64.dll

@golubaca您可以查看我当前资源的存储路径和程序中编写的路径。有什么需要注意的吗？对win10有什么特殊要求吗？

anything

I also encountered the same problem, when I thought it should be opencv problem, it should be that the corresponding parsing library was not loaded, I was trying to load opencv_videoio_ffmpeg.dll
