This patch takes care of the opposite problem: we don't want an old frame being accidentally NOT erased by a new one with the same timestamps just because these overlaps make highestPresentationTimestamp very slightly higher than the frame PTS. This bug in practice causes some frames of the old quality to not be erased when the new quality is appended, resulting in some seemingly still frames from a different quality appearing at some points during WebM video in presence of quality changes. This bug can be reduced to this minimal test case that illustrates the timestamp imprecission of a typical WebM file: function sampleRun(generation) { return concatenateSamples([ makeASample( 0, 0, 166667, 1000000, 1, SAMPLE_FLAG.SYNC, generation), makeASample(167000, 167000, 166667, 1000000, 1, SAMPLE_FLAG.NONE, generation), makeASample(333000, 333000, 166667, 1000000, 1, SAMPLE_FLAG.SYNC, generation), // overlaps previous frame makeASample(500000, 500000, 166667, 1000000, 1, SAMPLE_FLAG.NONE, generation), ]); } After appending this twice it would be expected that the second generation takes fully over the first, since the timestamps are completely the same. Due to the bug, sync frames with an overlap, like the third one in that list, actually persist from the first generation, due to lack of tolerance when comparing the start of a new frame with highestPresentationTimestamp. This patch introduces the tolerance in that case too to fix this problem. 1517910 1 365062 aboya 2019-03-18 14:14:23 -0700 Created attachment 365062 Patch 1518246 2 365062 commit-queue 2019-03-19 07:38:50 -0700 Comment on attachment 365062 Patch Clearing flags on attachment: 365062 Committed r243138: <https://trac.webkit.org/changeset/243138> 1518247 3 commit-queue 2019-03-19 07:38:52 -0700 All reviewed patches have been landed.
