OpenCV 4.5.3 and FFMPEG 4.2.4 (with SRT support) hardware accelerated on NVidia Jetson

Unfortunately, NVidia Jetpack 4.5.x for Jetson Nano, Xavier etc. comes with OpenCV 4.1.1 and FFMPEG 3.4.8 compiled without any hardware (GPU, CUDA) acceleration and without SRT support.

Retrieving current OpenCV build information:

$ python3

import cv2

ndevenish

cmake_minimum_required(VERSION 3.5)

# Find python and Boost - both are required dependencies
find_package(PythonLibs 2.7 REQUIRED)
find_package(Boost COMPONENTS python REQUIRED)

# Without this, any build libraries automatically have names "lib{x}.so"
set(CMAKE_SHARED_MODULE_PREFIX "")

# Add a shared module - modules are intended to be imported at runtime.
