For a test, I am running Back to the Future 2, which is encoded with VC-1 video. These Amlogic boxes will NOT play that format without stutter, multiple frame skipping, etc. I am using Superceleron’s ATV port on this Beelink GT-King. My TV is a Samsung 4k (non HDR) and my AVR is a mid-range Yamaha.
Because all of my boxes running on an Amlogic SoC ( I have many), cannot play the VC-1 codec, I use Emby client, because the Emby server does the transcoding.
To test the temp range, I am using Kodi 18 with the Emby skin (it does NOT do any transcoding). I am playing Back to the Future 2 for about half and hour, and the temp is hovering around 61 to 62C. The ambient temp is around 23C (73f). The stats show "Video decoder: amc-VC1(S)(HW)
Edit: By rapidly scrolling through home videos and pics, got it to get up to 72C and holding at 70C.
Edit: As long as I stayed in Kodi (about 5 minutes), the temp hovered between 70C and 71C. As soon as I exited Kodi, to the main Android home screen, the temp immediately dropped to 60C, then down to 55C. If I check it again, in half an hour, it should be in the 40’s.
Unlike my Amlogic S912 boxes that hit 100C or more, this temp does not bother me.
Of course, when the dev’s on here create CoreELEC port for the “King”, everything I have will be hardware decoded, so the temps should stay well in acceptable range for me.
These are just my 2cents.
