@jghodd This was issue due to old ffmpeg version used in the tree. Patch related: https://aur.archlinux.org/cgit/aur.git/commit/?h=palemoon-gtk3&id=baf41cd4b02e76ed434502dd1b8c152440240011 and upstream https://repo.palemoon.org/MoonchildProductions/UXP/commit/54043a8b0a3a272b1b7acd1e15ea356fbb20c2c6
Not related to your issue, first I would try building without using ccache.
