GStreamer: video rotation

[Honey_Patouceul]

First try boosting with jetson_clocks script.

If not enough, it would be possible to do that with PVA/VPI or with OpenCV/CUDA using GPU such as here :

Jetson Nano Real-Time Rotation

You may find some way to do that from here: You may have to first extend image into a greater resolution so that rotation won’t hide corners if these are significant. Once you can rotate the way you want, you may have to derive your own gstreamer plugin from nvivafilter (or nvvidconv) and add a dynamically settable property for dynamically providing your wanted rotation angle.

Note that the linked sample is from 2019, not tried it with recent JetPack releases. If the channels are not in the expected order, you may see this sample using nvivafilter also mapping RGBA frame from NVMM memory into a GpuMat, that has been tried in recent versions.
