KongQun Yang	f8a1cb66ad	Calculate presentationTimeOffset and Period@duration from segments ... Prefer timestamps from Video AdaptationSets if available - this avoids possible video playback jitters due to gaps. presentationTimeOffset is not applied to the first period as it may in negative dts which Chrome does not like: https://crbug.com/398141. It is safe to apply to subsequent periods as the actual offset applied takes Period@start into consideration: offset = Period@start - presentationTimeOffset The result timestamp with offset applied is close to Period@start, so it is unlikely to result in a negative dts value.

KongQun Yang	d9e7e2f1d0	Generate two sample entries only if there is clear lead ... This addresses playready broken with clear lead = 0. clear lead != 0 is still broken with playready on Edge. We think it is likely an Edge bug, which does not support multiple sample entry boxes, thus does not support clear lead. b/37913785 Change-Id: I7adb77a913dccf669153b03b31b4a1e1c98d1cb0	2017-05-15 14:13:52 -07:00
