What are the manifest and license server URIs?

What configuration are you using? What is the output of player.getConfiguration()?

{
   cmcd: {
    enabled: true
  }
}

What did you do?

1. Start playback of any stream
2. View the network requests for any video or audio segments and inspect the CMCD query string

What did you expect to happen?

• The tb (top bitrate) property should honor bitrate/size ABR constraints and only report the top playable bitrate.
• The tb property should also only report the bandwidth for that segments type (audio, video, muxed).

What actually happened?

• The tb property is the same for all requests, and it's locked to the bandwidth of the highest variant in the manifest.
• The tb property is the same regardless of the segment type.
