RTMP to Discord stream (GoLive) conversion

Overview

This guide sets up nginx to convert a RTMP stream to HLS, which then can be opened in browsers. Discord can then take advantage of Chromium's tab sharing feature to stream the HLS stream. Only a few seconds of latency are added, which is acceptable for most applications.

Note: If your goal is to just get audio streaming working on Linux, this guide might be helpful (It results in lower FPS for me, however):

Subject: [PATCH] Hack in C++ support

Also via a unusual method to update the musl version without creating a huge
diff that give won't accept.
musl needed to be updated because libc++ depends on a newer one than the one
provided.
