Which video did you test with? I just tried with a 1080 Hi10P file on the Shield TV, and I was very surprised to see it play back flawlessly.

Hmm how do you get it to play back properly? I have hickups all the time (examples are anime: The heroic legend of arslan / dragon ball super and well allmost any other anime).

I just played it. Default settings all around.

It was a version of Cowboy Bebop, but for further details I imagine it'd be best to privately message you? Smile

Can it be because I use 4k resolution that it stutters??

It plays back great with that as well. If I had to guess, it's because I'm using v16RC2, and mediacodec surface is used, which is big for 4K TVs. 4K was more CPU intensive in v15 because of the hack used, IIRC.

hmm I only used an old beta wich only went 1080 Sad

. I might give rc2 a try then Smile

thanks.

Ok I am using the RC2 now. I dont really like the way it makes my menu`s go 1080 instead of 4k. I liked that more in kodi 15.2 Sad

. I tried hi10p yesterday and it is much better but the menu`s are just crappier Sad

Actually shield is fine for 1080p hi10p up to 20mbps
For 720p hi10p, even Snapdragon 600 or A6X won't have much trouble

Howeved there is an unfortunate bug in kodi that it does not always utilize all the cores on a shield TV

I was using the old 15.2 on that it didnt work at all. on 16RC2 it works without any hickup.

I have tried a lot of builds from 15 to 17 alpha
It seems Kodi can only utilize CPUs that were online when it was launched
For me, the only way to enable all four cores in Kodi is to launch Kodi while Geekbench is running in the background, which is ridiculous

~~Ned Scott~~ · 2016-02-01, 23:23

Are you sure you just didn't have something running in the background at the same time? Probably the reason it worked with geekbench running is because geekbench will cause other background processes to quit (in order to get good benchmarks).

If I do not run Geekbench, Kodi will only recognize CPU0 and CPU1, perhaps CPU2
There is about 1 in 100 chance that Kodi would recognizes CPU3 because for the most of time CPU3 is offline. CPU3 wont be online unless there is serious workload, which is not likely to be the case if Geekbench is not running

~~Ned Scott~~ · 2016-02-02, 20:32

I don't think it works like that. Plus, I've never had to do that and Kodi is always able to use all of the CPU cores.

Hmm what a4840639 says actually makes a bit of sense because I only see CPU0 and 1 a lot. Sometimes CPU2 pops up as well. Let me test it later with geekbench open as well :O.

Okay, I think I see what it might be. There's a power saving setting on the Shield that I have set to full.

Android TV home screen -> Settings -> Device -> System -> Processor mode -> Max performance

This might be what is "sleeping" the other CPU cores? I'm not sure how all that works, but it's the only thing that I can think of that might be different on my Shield. The setting warns that this might increase the fan noise, but I've never noticed it when playing video. Only when playing games like Half Life 2.

DJ_Izumi · 2016-02-04, 04:13

Why would a set top box with no power source other than AC have any power setting other than 'Max Performance' on the CPU? It's like a 35w device. o.O
