You may check how to do rotation through NvBufSurface APIs and apply it to

I am using nvarguscamerasrc from this post
Did the changes in sources\apps\apps\common\src\deepstream_source_bin.c and saved it
Did the changes in sources\apps\sample_apps\deepstream-app\Makefile and make
But how will it reflect on my python app ?
For now we support using NvBufSurface APIs in C code. Not supported in python code. If you use python, please download the source code of gst-nvarguscamerasrc, apply the rotation in the source, and rebuild/replace the prebuilt lib in
