Macos – export to MP3 from quicktime API

Remove existing files from the repository:

find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

Add this line:

.DS_Store

to the file .gitignore, which can be found at the top level of your repository (or create the file if it isn't there already). You can do this easily with this command in the top directory:

echo .DS_Store >> .gitignore

Then commit the file to the repo:

git add .gitignore
git commit -m '.DS_Store banished!'

I'm afraid there is no standard key for this kind of metadata. You might try to use a reasonably fitting standard key like

kQTMetaDataCommonKeyInformation,

kQTMetaDataCommonKeyDescription or

kQTMetaDataCommonKeyProducer

although this wouldn't be 'standard' (i.e. would most likely only be processed correctly by your application).

On the question which value format to use this sample code and Q&A article (although it is not exactly fitting) might set you on the right track:
