Hi,
There is a sample of doing 180-degree rotation:
Since the resolution is the same after 180-degree rotation, it is a simple case.
90-degree rotation is a bit complicated. Possible solution is to run the pipeline:
nvarguscamerasrc ! 'video/x-raw(memory:NVMM),width=1920,height=1080' ! nvvideoconvert ! 'video/x-raw(memory:NVMM),width=1920,height=1920' ! nvvideoconvert ! 'video/x-raw(memory:NVMM),width=1080,height=1920' ! nvstreammux ! nvinfer ! ...
You can add prob callback to source pad of first nvvideoconvert plugin and do 90-degree rotation.
