Need help on 4K Video playback

[leonqin]

Hi guys,

I want to make myself a 4K video player with Rock64. I've got a 2GB version of it. I've tried some combinations of OS images and players. So far, my Rock64 can't play 4K video smoothly. No problem with 1080p videos. The list of OS and players combinations I tested is as below:

android-7.1-rock-64-rock64_atv-v0.3.13-r115-raw.img + kodi-17.6-Krypton-arm64-v8a.apk

android-7.1-rock-64-rock64_atv-v0.3.13-r115-raw.img + MX Player 1.10.2.1 beta.apk

android-7.1-rock-64-rock64_atv-v0.3.13-r115-raw.img + VLC Player (default player in the image)

LibreELEC-RK3328.arm-9.0-devel-201807011300-d46baa3-rock64.img + Embeded Kodi

LibreELEC-RK3328.arm-9.0-nightly-20180816-eef941c-rock64.img + Embeded Kodi

LibreELEC-ROCK64.aarch64-8.2-devel-20171004193222-r26173-gd404dbb.img + Embeded Kodi

Armbian_5.42_Rock64_Debian_stretch_default_4.4.124_desktop + Embeded MPV

Could anybody please tell me how to configure my rock64 for smooth 4K video playing?

P.S. the 4K video I tested is encoded with H.265.

Thanks a lot!
