I think you this is not the bytestreamTrackId - you probably want to rename the
member in trackInfo.

Done.

     trackInfo.kind = blink::WebString::fromUTF8(track->kind());
     trackInfo.label = blink::WebString::fromUTF8(track->label());
     trackInfo.language = blink::WebString::fromUTF8(track->language());
     trackInfoVector.push_back(trackInfo);
   }
 
   client_->initializationSegmentReceived(trackInfoVector);
 }
