static builds of mp4box
I know this isn't actually ffmpeg, but I think of mp4box as being ffmpeg-adjacent so I thought I'd ask here. Does anyone know if there are reliable static builds of just mp4box online anywhere? All I seem to be able to find on GPAC's site is either a big ol dynamically linked install, or instructions on how to build the mp4box-only binary locally yourself https://github.com/gpac/gpac/wiki/Build-Introduction

I have quite a few movies that fail to transcode due to unknown audio tracks. Any way to fix that?
If they're MKVs, MKVToolNix's header editor makes it easy to change the language tag of an audio track. For MP4 you could either remux them to an MKV (also using MKVToolNix) and change the language tag in the process, or use a command-line tool like MP4Box to change the language while keeping the MP4 container without reencoding.

Defining Audio Tracks
At least for MKVs, you can use MKVToolNix's header editor to add a name to the audio tracks, which most Plex clients will pick up on (e.g. in the web app: https://i.imgur.com/awhU0Z6.png). For MP4 containers, I think MP4Box can do this (one of their examples is "replace the label on an audio or subtitle track"). Other containers probably have their own methods, but I'd probably just throw them into MKVToolNix to move the streams to an MKV and edit the audio track names at the same time.
