Playing a video from failiover enabled node lists multiple audio streams in display page

[elv-gerald]

We are adding a new feature for live streaming that allows for failover urls included in the master playlist. I noticed whenever I am watching a stream from a node that has failover enabled, the display tab lists multiple audios even though they are fail over audios.

I have this build deployed to sv3-003. Here is test stream that is running 24/7 and is public if you want to test. Let me know if it goes down.

Here is what the playlist will look like in case you need an example. This failover feature is ONLY for hls playlist.txt

[elv-kevin]

I need a key to access this stream in app so I can see how the players handle failover, can you give me details?

[elv-kevin]

this is what these 4 audio tracks look like, there's nothing that differentiates any of them from normal audio tracks.

Added @elv-peter to this. He will have a better idea of this on an implementation level.

[elv-kevin]

however, it looks like elv-player handles audio track switching differently. I think the stream sample does it in a way that digs too much into the internals of hls.js

[elv-kevin]

I will switch it to use the same as elv-player-js, no need to change anything I think

[elv-kevin]

this is fixed on demo. I've got another ticket (https://github.com/qluvio/elv-apps-projects/issues/233) that's waiting on some changes to the embed player to be deployed before I can update prod

[elv-peter]

Probably not needed, but I think the STABLE-RENDITION-ID is the same for redundant streams.
