I am using the 4.8.5-r1.2 version of the Shaka Player that is in the docs. I find that when I pause the vid for maybe half a minute the vid is unable to resume and if it does resume it is only after a long delay.
I have also found this error in the same apps that are provided by amazon in the sports-app and video-sample which makes me think it might be an issue with how its implemented.
Any information would be appreciated.

When pausing video on Shaka Player if paused for too long and you try to resume play the video will stall and then jump further ahead of the video. It causes components to rerender unexpectedly. Other behavior seen is that it will stutter forward along the video until it resume playing. This behavior is both in my implementation and in the sample apps that are provided that use the Shaka Player. Also seems that audio and video are not synced
