Details

Steps to reproduce:

  1. Configure a RTCPeerConnection with multiple simulcast encodings using addTransceiver
  2. Add a video track obtained from getDisplayMedia
  3. Observe outbound RTP video stats

Can use this fiddle and look at stats in the console output: https://jsfiddle.net/5ve4gbjx/3/

Actual results:

Only the first listed encoding is sent. Depending on the ordering, this could mean we only send the lowest quality stream.

Expected results:

I'd expect to see all encodings configured as active to be sent regardless of the track type.
