We currently refresh repeatedly in this case. According to the DASH spec omitting minUpdatePeriod indicates that the manifest does not change, and therefore we should not refresh. I think it might be valid to omit minUpdatePeriod in a dynamic manifest if relying exclusively on EMSGs to trigger manifest refresh. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=191420247
