@FlixNow @KJKingJ @Stephen3001 We have a Plex Media Server release (1.9.0 for Plex Pass) coming imminently that contains a bunch of improvements to Auto Quality. We’re hoping that it resolves the 1.8.1-1.8.2 regression that you’re seeing with Auto Quality Preview on iOS/Android.
@FlixNow
These logs are helpful, particularly the Plex Transcoder Statistics.2.log log. I can see the mistake that the server is making during bandwidth allocation. Can you re-test on 1.9.0 when released and let us know? If it still has issues there, providing the same logs would be very helpful for us.
Note, one usage recommendation:
The default starting quality in your client’s global settings should usually be lower than your connection speed, allowing Auto Quality to scale up after starting. While we support the scenario where you start too high and then allow quality to decrease, the smoothest playback behavior is going to come from starting at a lower quality (such as the default of 2 Mbps 720p) then allowing Auto Quality to increase quality over time.
It sounds like you were hitting issues with that scenario, too, but just wanted to clarify the optimal settings there. In your iOS playback from the logs, the client is downloading at very close to the 17.3 Mbps starting quality, but with fluctuating bandwidth that ultimately ends in a stall.
