Description Enrique Ocaña 2023-08-22 08:18:28 PDT 
Some web application code needed for HbbTV certification of a commercial device needs that the actual track IDs provided to JavaScript when playing regular video match those muxed into the media container. Currently, those track IDs are synthesized as A1, A2, A3... and V1, V2, V3...

Note that the implementation of this feature for MSE is out of the scope of this bug.
