HLS labels & backup streams compatibility?

Apple's docs suggest that to support redundant streams, you can just interweave the backup playlists in along with the primary playlists. See

Akamai also suggests doing this for this "Media Services Live" service for HLS streaming.

The problem I found is that when JW Player builds the HLS labels, it looks at each playlist within the main playlist and assigns a label to it - so this creates duplicate entries - two for each resolution / bitrate (backup and primary).

I understand this is a difficult problem to solve, since I don't see how JW player could really determine which is the primary and which is the backup.

Just wanted to put this on your radar
