There could be rounding errors in MSE which could cut the first key frame of the representation and thus cut all the frames until the next key frame, which then leads to a big gap in presentation timeline which stalls playback. Adjusting presentationTimeOffset (PTO) by -1, i.e. backing off PTO by 1 to compensate for the possible rounding error. It should not cause any playback issues as it is small enough. The workaround can be removed once the problem is handled in all players. The PTO adjustment is configurable with command line flag: --pto_adjustment, with value set to -1 by default. b/71808910 Change-Id: I9c4d1e2ee84008b859a3638a8146c910cead1f15 |
