Unified Packager smoothly handles advanced features for adding multiple audio codecs, such as DTS Express, Dolby Digital Plus/Atmos and HE-AAC v2. Adding subtitles is easy because Unified Packager supports SRT, DFXP, ISMT, STPP or WebVTT.
How it works
As a software program, Unified Packager takes MP4 files as input to produce segmented output in HDS, HLS, MPEG-DASH and MSS formats. DRM can be applied using the command-line options, whereas CPIX may be used to specify multiple keys.
