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：
cudaMemcpy((void*)src_data(void*)surface->surfaceList[frame_meta->batch_id].dataPtr,surface->surfaceList[frame_meta->batch_id].dataSize,cudaMemcpyDeviceToDevice);
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);
nv12_mat.copyTo(nv12_mat_out(area_new));
cudaMemcpy((void*)surface->surfaceList[frame_meta->batch_id].dataPtr,(void*)nv12_mat_out.data,surface->surfaceList[frame_meta->batch_id].dataSize,cudaMemcpyDeviceToDevice);
