How to replace the data in the pipline (nvosd-sink) in Jetson?

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU)
• DeepStream Version
• JetPack Version (valid for Jetson only)
• TensorRT Version
On the PC side, I realized how to replace the data in PIPLINE and how to achieve the function of replacement on jetson.。The code that can run properly on the PC port is as follows:
cv::cuda::GpuMat nv12_mat=cv::cuda::GpuMat(height, width, CV_8UC4, src_data,surface->surfaceList[frame_meta->batch_id].pitch);
cv::cuda::GpuMat nv12_mat_out=cv::cuda::GpuMat(height, width, CV_8UC4);
cv::cuda::resize(nv12_mat, nv12_mat, cv::Size(512,512 ));
cv::Rect area_new = cv::Rect(512, 0,512, 512);

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
