We currently switch without downloading overlapping segments, but we do not actually switch more aggressively. This change fixes this. Note there's an implicit assumption made that if one media playlist declares independent segments, the others will too. This is almost certainly true in practice, and if it's not the penalty isn't too bad (the player may try and switch to a higher quality variant one segment's worth of buffer too soon). ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=167120992
