the normal place to put the encryption information in the segments is in a senc box, and this is not the case in this file, but they seem to be placed in a [uuid] box instead. This is allowed, but not supported by mp4ff library at the moment. In principle the data can be put in any place given by the offset in the saio box

and:

If the Override TrackEncryptionBox parameters flag is set, then the SampleEncryptionBox specifies the AlgorithmID, IV_size, and KID parameters. If not present, then the default values from the TrackEncryptionBox SHOULD be used for this fragment.
