Subtitle stutter 8.90.3

Kodi
17

rb-krypton19

and it’s no matter with whitelist settings。

18

I guess this only happens on Odroid. I have a chinese s905x box and there is not stutter

19

But I also noticed on a S905D BOX. It will drop a frame just when subtitle displaying. if you disabled subtitle or no subtitle shows, no stutter.

20

I fresh new install 8.95.2, playback the sampl file, I uploaded new kodi.log to MegaKodi.log.

21

The Subtitle stutter issue still present on the last nightbuild.

This issue not happened on all video files but some kind.

So I upload a sample.mkv and here is the logofiles

Developer please take a look and try to fix this.Please,Please ,Thanks a lot.

Look here: Smart Redraw

23

Smart Redrow does not work, ie it does not eliminate subtitle stutter on my X92_S912 box.

24

What about dirtyregions then? As far as I know it does work, and gets rid of this issue.

25

dirtyregions also does not work

26

Dirty regions work for me, so it’s still my only option on S912, because I have to use subtitles extensively.

I have just set Smart Redraw, but stutter still remains. It seems that a little less, but still very noticeable when a subtitle is about to appear or it has just appeared and the scene moves.

I also use subtitles in all videos, since I watch everything in original version.

I have a Vorke z6 (S912) box.

Do you have stutter also with dirty regions enabled? That option solves the stutter completely on my S912 box, except on one video, 720p/50Hz coded with h265, where the slight stutte is still (not frequently) noticeable.

29

Yes,I tried dirty regions and smart redraw, but both not work.

As I said,This issue not happened on all codec video files but some special kind.
Have you playbacked the sample.mkv I uploaded?
on my case, odriod c2 and S905D box with the lastest release version and nightbuild coreelec,the stutter all noticeable. But with Raybuntu’s rb-krypton19 build for odroid c2, no stutter,very smooth.
So, I think maybe Raybuntu can fix this issue.

Yes, I tried it and answered to you on LE forum…

Maybe you didn’t implement the commands properly, or your C2 does not like disabling dirty regions…

31

I typed these code in advancedsettings.xml

<gui>
<smartredraw>true</smartredraw>
<algorithmdirtyregions>0</algorithmdirtyregions>
</gui>

reboot ,no work.
and the CPU’s temperature raise high.

32

8.95.5 the issue remains.

This is my advancedsettings.xml:

<advancedsettings>
  <gui>
    <algorithmdirtyregions>0</algorithmdirtyregions>
    <smartredraw>true</smartredraw>
  </gui>
</advancedsettings>

First line stops stutter on files like this sample
Second line eliminates stutter on files like this sample, which first line does not eliminate.

So I keep both lines and CPU temp does not rise at all.

34

I tried already, no matter which line first ,all stutter.
Anybody who have odroid c2 Please playback the sample mkv, confirm stuttering or not.
Thank you

I have the same problem, stuttering with subttiles, seems that a frame is lost or doubled when sub appears.

36

Yes, that’s what I said stutter meanings.
