You have one sink too many.You should remove the ximagesink.

I want to stream a MJPEG video from my ethernet camera with OpenCV and
I have tried to open the stream with the following gstreamer pipeline:
"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);
but the previous code returns me the following error:
OpenCV Error: Unspecified error (GStreamer: cannot find appsink in manual
) in cvCaptureFromCAM_GStreamer, file
VIDEOIO(cvCreateCapture_GStreamer (CV_CAP_GSTREAMER_FILE, filename)): raised
error: (-2) GStreamer: cannot find appsink in manual pipeline
in function cvCaptureFromCAM_GStreamer
I managed to stream the the same RTSP source with H264 and H265 algorithms,
MJPEG is the only format that doesn't work, then I suppose that is a
gstreamer pipeline problem..
