Jetson Nano Real-Time Rotation

You may find some way to do that from here:

nvivafilter customer-lib implementation (code available)

I think there might be two issues with cv::cuda::rotate: Main one is reallocating buffer for its output. Any data written out of buffer at pdata will be lost Second one is maybe rotate doesn’t work fine for alpha channel. You may try: static void cv_process_RGBA(void *pdata, int32_t width, int32_t height) { /* Create a RGBA GpuMat with data pointer */ cv::cuda::GpuMat d_Mat_RGBA(height, width, CV_8UC4, pdata); /* Convert into a RGB GpuMat */ cv::cuda::GpuMat d_Mat_RGB(height…

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.
