# 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.
