Cherry pick PR #807: [android] Reset frame rate estimator when the stream fps changed (#807) #1062
Conversation
… the stream fps changed (youtube#807) Refer to the original PR: youtube#807 When playing a stream, the key operating rate is set to MediaCodec for resource planning. It's calculated by the playback rate and the estimated fps. While the latter is calculated by the number of rendered frames in duration. When the stream fps is changed, the estimated fps will be affected by the frames already rendered with the old fps and slowly adjusted to the new fps. This may lead to insufficient resources prepared for the stream and cause some performance issues. b/290409989 Change-Id: I5126794d0ac98d29fc8405359bcb4f62dc444308

Hi - i just noticed your question about the cherry-pick. Generally there are no more planned releases from We can still of course apply the change, especially as this is a small and clean bug fix, but we do not expect this to get deployed. |

Thanks for the information. Wondering will the existing devices upgraded to 24* in the future or if they will stay in the 23 latest release? |
It depends on the device. For Cobalt 24 supports Starboard versions 13, 14 and 15, so any older devices on Starboard 12 and older wouldn't be upgradeable anymore. Of course, for devices that get updates through appstores ( e.g Android TV), they all should eventually get updates. |

I've applied the fix here - and thanks again for the contribution. |
