if you have mp4 files, does it really matter which codec you use, or is there a generic one that is most universal for all platforms?
Thanks for reaching out.
Data is compressed with the gzip compression codec by default. If you want to use a different kind of compression, you must contact the Audience Manager team, which will evaluate with engineering if your compression codec can be supported.

Thanks a lot for your answer
