Basic video playback in OpenGL using FFmpeg (Part 1)

This is an extract taken from the 16th of November livestream that can be viewed in its entirety here: https://www.youtube.com/watch?v=u_ARZKClhpk In this series I am building a real-time video processing application from scratch using FFmpeg, OpenGL, and GLFW, all written in C++. The code is available on Github: https://github.com/bartjoyce/video-app The previous video: https://youtu.be/Y7SUm7Xf1sc This part of the livestream builds on what we've done before. I'm adapting my existing code that can decode and render a single frame from a video so that it can now stream the entire video.
