- When calculating the downloaded percentage in DASH, there was no way to disambiguate between 0 of 0 segments being downloaded because there are no cached indexes (i.e. 0% downloaded) and 0 of 0 segments being downloaded because the index defines 0 segments (i.e. 100% downloaded). - Also replace use of NaN with a named constant. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=194453202
