You must define "smoothly" and "video source parameters". There is many problems/bottlenecks (hints for linux not android):
  • videoplayer must use HW acceleration/MPP "cat /sys/kernel/debug/pm_genpd/pm_genpd_summary" must be "active" during video play without postprocessing and must use direct DRM output (check this)
  • memory and CPU minimum speeds should to be increased for 4k(HDR) (check hints)
  • 4k video with 24/25/30/50 FPS should be ok, 4k video with 60 FPS sometimes not because rockchip MPP performance problems (check performance test)
  • your source of video file (sdcard,emmc,nfs,smb...) should have sufficient bandwidth
  • search this forum for more hints
I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" Angry. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
