My sample works when compiled with the Makefile from 00_video_decode sample… After further investigation, I discovered that the nvjpeg library must be linked for some unknown reason to make my sample work. (╯°□°）╯︵ ┻━┻
The “-Wl, - no-as-needed” flag is required because symbols from this library are not used in the sample.
Workaround:
cmake_minimum_required(VERSION 3.8)
