Tool/software: Linux
Dear e2e community,
I am using the latest processor SDK and AM5728 board
I have created a gstreamer pipeline, used shared memory as sink, created rtp packets and used AM5728's IP address as below
Open first terminal:
-->gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,width=640,height=480,framerate=10/1,format=YUY2 ! shmsink socket-path=/tmp/foo2 sync=true wait-for-connection=false shm-size=10000000
Open second terminal:
-->gst-launch-1.0 shmsrc socket-path=/tmp/foo2 ! video/x-raw,width=640,height=480,framerate=25/1,format=YUY2 ! jpegenc! rtpjpegpay ! udpsink host=192.168.2.207 port=5200
Below is my opencv program:
#include <opencv2/opencv.hpp>
using namespace cv;
using namespace std;
#include <iostream>
#include <fstream>
#include <string>
int main()
{
VideoCapture camera0("rtp://192.168.2.207:5200/?action=stream");
while(camera0.isOpened()) {
Mat frame0;
camera0 >> frame0;
imshow("Video0", frame0);
int c = waitKey(1);
if(27 == char(c)) break;
}
return 0;
}
I get the following error:
OpenCV Error: Unspecified error (GStreamer: your gstreamer installation is missing a required plugin
) in handlemessage, file /home/gtbldadm/processor-sdk-linux-krogoth-build/build-CORTEX_1/arago-tmp-external-linaro-toolchain/work/am57xx_evm-linux-gnueabi/opencv/3.1+gitAUTOINC+b4f54ac48c-r0.tisdk7/git/modules/videoio/src/cap_gstreamer.cpp, line 1692

can you please help to fix the above issue?
Thanks,
