  • moof parsing logic had to ignore some bytes, so instead of returning bytes and time seperately. FetchLoader calculates the throughput as stated in LoL+ paper and sends that data directly.
  • in ThroughputHistory that direct calculated throughput calculated value is used if it is present. Otherwise traditional throughput calculation s used.
