+# Description:
+#   - Downloads and builds FFmpeg from GitHub (https://github.com/FFmpeg/FFmpeg)
+#   - Supports specific version override via FFMPEG_VERSION (e.g. n7.1.1)
+#   - Supports build profile via FFMPEG_TYPE:
+#       - minimal : x264, vpx, mp3 only
+#       - medium  : adds subtitles, fonts, opus, vorbis
+#       - full    : adds dav1d, svt-av1, zlib, numa
+#       - binary  : downloads static build (johnvansickle.com)
+#   - Defaults to latest stable version and full feature set
+#
+# Notes:
+#   - Requires: curl, jq, build-essential, and matching codec libraries
+#   - Result is installed to /usr/local/bin/ffmpeg
