I have written a script to group and collect audio track info, however i found out that renaming preview and effective preview do not match and It's driving me crazy.
below my code
Groovy: Select all
{
String audioToString(){
def myAudioList = []
for (int i = 0; i < audio.format.size(); i++) {
def track = [:]
track.format = audio.format[i].toString().removeAll(/[^A-Z0-9]/)
track.channels = audio.channels[i].replaceAll(/\[|]/,'').replace('2', '2.0').replace('6', '5.1')
track.language = audio.LanguageString3[i] != null ? audio.LanguageString3[i].lower() : "und"
myAudioList << track
}
def groupedAudio = myAudioList.groupBy { "${it.format} ${it.channels}" }
def result = []
groupedAudio.each { key, tracks ->
def languages = ""
tracks.eachWithIndex { track, index ->
languages += track.language
if (index < tracks.size() - 1) {
languages += " "
}
}
result << "${languages} ${key}"
}
return result.join(" ")
}
}
But what it really renames is
as you see the codec changes from AC3 to EAC3 for no apparent reason, the thing is done randomly on other files as well
any help?
How do you know that EAC3 / AC3 is or is not correct for the file at hand? Please

Note that the format code you posted does nothing. It is merely defining a function which is then never called, thus the code yields no result. Please copy & paste the entire code.
e.g. use this format on your Onward (2020) sample file to see what
