[FFmpeg-devel] normalize-audio and video files

[Emanuel Berg]

This zsh, using ffmpeg and normalize-audio, seems to
do it. But it is slow. Remember normalize-audio is
lightning fast so time is spent getting and putting
together the audio with the movie. Perhaps it can be
optimized somehow - do tell, if you know...

The code:

normalize-audio-in-movies () {
    local -a movies
    local -a songs
    local name
    local audio
    local ext=mp3
    movies=($@)
    songs=()
    for m in $movies; do
        get-audio-from-movie $m
        name=${m:r}
        audio=$name.$ext
        songs+=($audio)
    done
    normalize-audio $songs
    for m in $movies; do
        name=${m:r}
        audio=$name.$ext
        put-song-into-movie $audio $m
    done
}

put-song-into-movie () {
    local song=$1
    local movie=$2
    local name=${movie:r}
    local ext=${movie:e}
    ffmpeg -i $song -i $movie ${name}-norm.$ext
}

get-song-from-movie () {
    local movie=$1
    local name=${movie:r}
    local song=$name.mp3
    ffmpeg -i $movie $song
}
