• GeForce GTX 1660 Ti Mobile  
• DeepStream 6.1  
• Ubuntu 20.04  
• TensorRT 8.2.5.1  
• GStreamer 1.16.2  
• NVIDIA driver 510.47.03  
• CUDA 11.6 Update 1

I created custom LPD and LPRNet model. Now I want to add rotating on the angle found plate before the recognition. I want to do this:

Is it real with DeepStream? If it is real, how I can do it?

@YaroslavScheg We cannot support rotation in any angle. You can realize it by yourself. Or if you just want to rotation 90°,180°,270°. You can refer our nvvideoconvert plugin.

So, for this I need to realize custom plugin?

Yes， you can write a plugin or you can add your image rotation algorithm in our open source code.  
About how to get picture, you can refer our deepstream source code:

```auto
/opt/nvidia/deepstream/deepstream-X.X/sources/apps/sample_apps/deepstream-image-meta-test

```
