Linux SPEED: 0.100% in log - normal?
#1
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
878054 (post)
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

My xrandr Output with Openelec 5.0.1 and a ASUS Chromebox

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

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

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

Ok, but what is “the issue“?

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

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

Make a backup please, before updating to this build.
