The Cadmore management portal offers the possibility to encrypt audio and video files. This means that the file can only be played by authorized users. This encryption requires an authentication interface between the brill.com / Pubfactory platform and Cadmore. Since this is not (yet) available, the Encrypt-option should be turned off to be able to play the file in an article or chapter. If turned on, a message appears that the user doesn't have permissions to play the file.
