# Stage 3: Static ffmpeg binary (avoids apt ffmpeg pulling mesa/libllvm for
# hardware acceleration we don't use server-side).
#
# Resilient download: johnvansickle.com is the primary source but it's a single
# self-hosted host with no CDN and goes down intermittently. Use bounded-timeout
# retries, then fall back to a pinned BtbN/FFmpeg-Builds autobuild. Every archive
# is SHA256-verified before extraction. The two sources have different internal
# layouts, so locate the binaries with `find` rather than a fixed strip path.
