Question

我想用OpenCV和Gstreamer从我的以太网相机中流式传输MJPEG视频。我试图使用以下gstreamer管道打开流：

std::string pipe( 
                "rtspsrc location=rtsp://192.168.1.219:554/video.pro1 ! application/x-rtp,encoding-name=JPEG,payload=26 ! " 
                "rtpjpegdepay ! jpegdec ! xvimagesink sync=false ! appsink" 
        ); 
cv::VideoCapture cap(pipe, cv::CAP_GSTREAMER);

但是之前的代码返回了以下错误：

OpenCV Error: Unspecified error (GStreamer: cannot find appsink in manual pipeline 
) in cvCaptureFromCAM_GStreamer, file /home/nvidia/Documents/CameraTests/src/opencv-3.3.0/modules/videoio/src/cap_gstreamer.cpp, line 796 
VIDEOIO(cvCreateCapture_GStreamer (CV_CAP_GSTREAMER_FILE, filename)): raised OpenCV exception: 

/home/nvidia/Documents/CameraTests/src/opencv-3.3.0/modules/videoio/src/cap_gstreamer.cpp:796: error: (-2) GStreamer: cannot find appsink in manual pipeline 
 in function cvCaptureFromCAM_GStreamer

我设法使用H264和H265算法流式传输相同的RTSP源， MJPEG是唯一不起作用的格式，那么我认为这是一个gstreamer管道问题..

感谢

使用RTSP协议传输MJPEG视频时出错
