Hi there, I'm noticing regular skipped frames, or duped can't tell when watching 23.976/24/59.94fps material (synch audio to display enabled and display correctly switching refresh).
The setup is intel Haswell refresh core i7 and setup as per the sticky here so I shouldn't have any problems at all like this.

It's barely noticable to most people but there's a definite regular stutter/dupe/drop/etc every 35-45 seconds or so I'd say.

The log window that brings up all the codec/frame rate/synch/bitrate details shows a play speed of "SPEED: 0.100%" for the video, I'm assuming this is what's at fault?
I don't notice this when watching live TV broadcasts that are 420i/50 or 1080i/50.

Is this normal?

Thanks.

Debug Log + /usr/lib/kodi/kodi-xrandr | pastebinit please

We need to discuss this 0.1% every half a year I think ...

Thanks for your reply fritsch.
Should have known I'd need a debug log thought it would be a straightforward "your edid is wrong or something".
Well it seems after all these years I'm still getting into bad routines and enabling/disabling stuff without really thinking.
It seems I had "sync playback to display" enabled along with "change refresh rate to match video", which basically do the same thing in reverse of each other.
My display can do 23.976/24fps/50fps/59.94fps/60fps so after reading a simple post here
http://forum.kodi.tv/showthread.php?tid=...#pid878054
That means I don't need to enable "sync playback to display". When that is enabled the output of the console doesn't even list "SPEED: 0.100%" which makes sense.
Video plays back normally to and can't notice a stutter.

This does raise a question though, why would those settings not be mutually exclusive in the GUI, since "sync playback to display" is clearly taking precedent? I note that even with "expert" settings enabled the method to achieve this isn't given as an option anymore, assume it's now in advancedsettings.xml?

I've uploaded a log, but only realized AFTER disabling sync playback to display (but with refresh rate changed to match video enabled, as I've always had on enabled)...
So it's prolly a waste of time and I've answered my own question? But would you mind telling me if the above is basically correct?

UPDATE
Seems the "Kodi Log Uploader" isn't working, and a log hasn't been uploaded to my email address :/
But it looks like there was no problem if my supposition above is right, could you confirm, thanks very much for your time, appreciated.

Post what I requrested in my original post. My setup use Sync Playback to Display with Method Video Clock.

Code:

DISPLAY=:0 /usr/lib/kodi/kodi-xrandr | pastebinit
cat ~/.kodi/temp/kodi.log | pastebinit

Video File is 23,976 720p (Mediainfo --> http://pastebin.com/1gFMYYvG)

Speed is 0,100% and Sync is +10% ?? Why is that with the correct 23,976 Mode used

[FernetMenta]

there is indeed an issue but due to fine adjust of ref clock it should not have much impact.

[john.cord]

Ok, but what is “the issue“?

[FernetMenta]

the issue is this ancient rounding magic in the code: https://github.com/xbmc/xbmc/pull/6356/files
although it used floating point it assumed refresh rate to be an integer

[john.cord]

Ok, and how do i achieve this

23,976 without any sync, speedup or whatever...

either apply the linked patch or disable passthrough audio and set sync type to resample.

[john.cord]

ok, so this will be in openelec in the near future so i wait but thx for reply! :-)

[fritsch]

Ping me later. Will PR those changes to OE.

Thx... updated fine!
