23.976FPS stutter, test files, and other FPS video stutter issues
The line should travel across the screen without and stutter. It matters not the speed it travels but whether it travels across your TV screen smoothly.

When I tested I saw stutter on 23.976fps, 29.976fps and micro stutter on 50fps. I'm using a direct box to TV connection with no AVR in between to take out that from any equation.

With regards the issue with stutter becoing more prominent after playing for some time that is the SMB issues which should be fixed isn't it? That's what I'm seeing via SMB use.

Finally this is already under discussion in another thread of your own making lets not have to post twice in two places:-

edit:

AVI Test Files
Watch the white line as it travels, does it stutter and does your display match the input fps.

Bluray stutter test
Bluray with five test files. BDlite may not play all five, make sure you leave running each file is around 1m7secs.

23976fps
24fps
25fps
2997fps
30fps
MKV files taken from the Bluray, watch the pendulum and check your display matches fps.

Read above, we do not want each and every firmware thread taken of course into 23.976fps. It has its own thread and is recognised as an issue in the release notes. So there is zero need to take hijack each and every firmware with the known issues.

RE: 23.976FPS stutter
Is Rockchip able to solve this huge problem?

For the Amlogic CPU's the problem is solved, right?

RE: 23.976FPS stutter
Can some tell me if it is a Android, Rockchip or a Cloud Media Problem?

Is it possible to fix the Problem.

Since 1 1/2 month I'am waiting for a working System.

I already give Cloud Media the chance to fix the known Bugs but if they can't fix this issue within a Month I will say Goodbye to Cloud Media an the very good community (the only reason to wait 1 1/2 months).

RE: 23.976FPS stutter
No big deal for me, I set the box to 1080P 60... 23.976FPS frame jump each 45 seconds is hard to notice..
Are you sure your stutter is not a different issue...?

RE: 23.976FPS stutter
I use the same configuration like you and I have the same Problem.

With my old media players (xtreamer prodigy and NetGear NeoTV 350) i hadn't any problems.

But there was no Kodi or HEVC Support.

Yes it is fixable, it's fixed on the Minix Neo X8-(H).

RE: 23.976FPS stutter
I think we should all run the same FPS test files through our setups and compare results. Those not using an AVR I believe suffer this far more than those of you that dont, stutter in general. Obviously not talking spmc/xbmc steaming here we are talking only playback.

We should also test using both your favorite software and the native player and from local and network playback.

Test files for stutter:
https://dl.dropboxusercontent.com/u/13560782/FPS.rar

Is the Minix Neo X8-(H) running the RK3288 as if its fixed for them it should be fixed for us as its a Rockchip issue and we are all awaiting them. If it doesn't use the RK3288 then it has no relevance.

Oh and its a Rockchip issue. If you read the release notes you can see it acknowledged by OH and they have reported it back to Rockchip. If you search the forum you'll be able to see when that was.

Better, but not good, imho.
However I tested to disable vertical blank sync and found that the playback was a lot smoother with it off.

On a side note, only the 25 and 50 fps files got a hdmi "resync" in SPMC
When I tried the testfiles on my A210 every file got a hdmi "resync"
