you are right. but they support 1080p, xbmc cant work well with 1080p on this platform

---

do you have any suggestion?

nobody can help you on 4K decoding on 3188, do more home work first before you post it out.

Can you tell us what MediaInfo (wiki) says for the file you tried to play?

[XBMC008]

1080P: Transformers
format: mkv...
all of the 1080p can't play well using XBMC on RK3188 and RK3066

thanks scott, i need your help

Hi XBMC team, who can help me? thanks.

Like I said, you need to run the program MediaInfo (wiki) on the file and tell us what it says. The basic info you've provided doesn't tell me enough information.
