+# Custom Gstreamer Element (GPU Usage)
+Deepstream SDK custom gst-element.
+(NVMM memory --> GpuMat)
+Sample Repo to get buffer from nvmm memory and map it to gpumat without going to/from cpu.
+It uses cuda programming to draw a filled rectangle. (basic preprocessing)
+
+## System Environment
+- Hardware : Jetson Orin AGX
+- OS : Ubuntu 20.04 
+- JetPack - 5.1.1
+  - TensorRT - 8.5.2.2
+  - Deepstream - 6.2
+  - OpenCV - 4.6.0 + CUDA
+
+
+## Installation
+```
+git clone https://github.com/RajUpadhyay/Deepstream-Custom-Element
+cd Deepstream-Custom-Element
+```
+
+Set your cuda version in the Makefile like this
+`CUDA_VER?=11.4`
+
+Now run make and sudo make install
+```
+make
+sudo make install
+```
+
+
+## Please set up nvinfer by yourself or refer [this](https://github.com/RajUpadhyay/Detectron2-Deepstream) repo
