[RK3399/RK3399pro][Android9.0] Android-＞Bootanimation-播放視訊:編譯版本user固件時,視訊無法播放的問題

測試平台

Platform: RK3399/RK3399pro

OS: Android9.0

現象

rk的Bootanimation自帶了開機動畫播放視訊的功能,具體的使用方法如下:

BOOT_VIDEO_ENABLE ?= true

之前主要編譯userdebug版本和eng版本的固件,都可以正常播放,目前有客戶提出user版本下無法播放.

分析解決

user模式下無法使用,主要是selinux的權限問題,解決更新檔如下
