The computer system I use is windows7. I use VLC to play rtsp://xx:[email protected], which can be played normally, but I have no success using it webcam, err := gocv.OpenVideoCapture("rtsp://admin:[email protected]")， It reports the error as follows Error opening video capture device: rtsp://admin:[email protected] But I can successfully call my local computer camera with the following code webcam, err := gocv.OpenVideoCapture(0) It can work successfully. I tried many methods: ①install ffmpeg ②install opencv_videoio_ffmpeg_64.dll and opencv_videoio_ffmpeg.dll But it still doesn't work
