Description
HLS calls for a loudness box:
2.19. In fMP4 files, you SHOULD provide loudness information by way of a loudness box ('ludt'). When present, the loudness box takes precedence over any loudness information in the audio stream.
FFmpeg can be used to normalize and provide this data (https://github.com/slhck/ffmpeg-normalize)
It would be helpful if loudness metadata could be provided on the command line and then written to the 'ludt' loudness box when using the dash and hls output formats
