Content and manifest requirements
Check the restrictions and requirements for streams and playlists (manifests), including DRM encryption keys.
Include and set the RESOLUTION property for each ABR stream in the manifest file. You must use Flash Player 14 or later.
If the DRM-protected stream is multiple bit rate (MBR), the DRM encryption key used for the MBR should be the same as the key used in all the bit-rate streams.
Must have the same bit-rate renditions as the renditions of the main content.
