You might want to add a method to parse the data e.g.
HostLookupResult ParsedRtcEventLog::GetHostLookupResult(size_t index);

 // Returns the MediaType for registered SSRCs. Search from the end to use last
 // registered types first.
 ParsedRtcEventLog::MediaType ParsedRtcEventLog::GetMediaType(
     uint32_t ssrc,
     PacketDirection direction) const {
   for (auto rit = streams_.rbegin(); rit != streams_.rend(); ++rit) {
     if (rit->ssrc == ssrc && rit->direction == direction)
       return rit->media_type;
   }
   return MediaType::ANY;
 }
 }  // namespace webrtc
