track id conflicts

[Scott Bengtson]

Hi there,

Recently been testing with a 4k stream. In order to do so I've updated the following from .TS to FMP4

mediaInfo.hlsSegmentFormat = cast.framework.messages.HlsSegmentFormat.FMP4

mediaInfo.hlsVideoSegmentFormat = cast.framework.messages.HlsSegmentFormat.FMP4

However, I continue to get an error here: 'textTracksManager.addTracks([track])' code that works fine with 720p stream. It's complaining about 'track id conflicts'. Do I need to have a different trackId for a 4k stream or any idea what's creating the issue?

Please advise.

Thanks,

Scott
