+# FFmpeg Wrapper Script for Volume Detection
+#
+# This script acts as a wrapper for the real ffmpeg binary.
+# It's designed to handle cases where 'ffmpeg -filter:a volumedetect'
+# doesn't output 'mean_volume:' (e.g., for image files or videos without audio).
+#
+# If 'mean_volume:' is not found in the real ffmpeg's stderr output,
+# it injects 'mean_volume: 0 dB' into the stderr stream.
+#
+# Setup:
+# 1. Rename your original ffmpeg binary.
+#    Example: mv /usr/bin/ffmpeg /usr/bin/ffmpeg.bin
+# 2. Place this script at the original ffmpeg's path.
+#    Example: cp this_script.sh /usr/bin/ffmpeg
+# 3. Make this script executable.
+#    Example: chmod +x /usr/bin/ffmpeg
+# 4. Ensure REAL_FFMPEG_BINARY points to your renamed ffmpeg binary.
+# ==============================================================================
+
+# --- Configuration ---
+# Point this to the actual ffmpeg binary after you've renamed it.
+# For example: /usr/bin/ffmpeg.bin or /usr/local/bin/ffmpeg.bin
