Is it possible to open an IP camera(RTSP streaming) with opencv video capture without ffmpeg or gstreamer backend?

1

I have cross compiled opencv without ffmpeg or gstreamer support.
This is output of command
getBuildInformation()

Video I/O:
    DC1394:                      NO
    FFMPEG:                      NO
      avcodec:                   NO
      avformat:                 NO
      avutil:                    NO
      swscale:                   NO
      avresample:                NO
    GStreamer:                   NO
    v4l/v4l2:                    YES (linux/videodev2.h)

using just V4l2 backend is it possible to stream rtsp using the videocapture.open api.

i tried

cap.open("rtsp://192.168.1.10:554/user=admin&password=&channel=1&stream=0.sdp?",cv::CAP_V4L2);
   if (cap.isOpened()) {
        dbg->error((const char *) "[OpenCV] Camera opened " );
    }

But it fails to open camera

nope.

you only have V4l/v4l2, and that’s for hardware, not for network.
