Hi.

I've been using XBMC on an iMac 2010 (Yosemite) plugged to a 1080p TV through HDMI for about one year, and was fully satisfied with the following settings :

• Adjust display refresh rate to match video : On start/stop ;
• Sync playback to display : On (A/V sync method : Video clock (resample audio)).

> The first one allowed me to adjust refresh of my TV when playing 23.976fps or 24fps files, avoiding the juddering 3:2 pulldown of 50/60Hz refresh ;
> The second one allowed me to force audio to keep synced with video on 23.976fps files, as Mac OSX cannot handle 23.976 and displays 24fps instead. With this setting, I was free from the annoying frame skip occuring every 41 seconds or so.

I stucked to XBMC 13.2 even since the release of Kodi, because when using Kodi, the refresh rate was not forced to 24 anymore : I could see frame skips, and pressing O on the keyboard showed me a refresh rate of 60 despite the "Adjust display" setting being on (same bug as the one reported here : http://forum.kodi.tv/showthread.php?tid=...st_1893799 ). It was not a problem for me to use a previous version as long as it worked fine.

Problem is, yesterday I watched a 23.976 movie, and saw some frame skips. I pressed O, and saw that even XBMC 13.2 did'nt manage to force 24Hz refresh anymore.

I thought of a problem certainly due to a recent Yosemite update, and decided to give Kodi 14.2 a try. There, I discovered that these two settings (adjust rate & sync playback) could not work together anymore : as soon as I launch a movie with these settings, Kodi crashes.

I have tried the same settings on a different Mac (MacBook Air 2011 Yosemite), same result.

I have tried to play a bit with advancedsettings.xml, and discovered that Kodi fails when trying to adjust refresh rate on 23.976, 24 and 25.

The followings settings cause a crash when launching a 23.976 video :

Code:
<video>

    <adjustrefreshrate>

        <override>

            <fps>23.976</fps>

            <refresh>23.976</refresh>

        </override>

    </adjustrefreshrate>

</video>

Code:
<video>

    <adjustrefreshrate>

        <override>

            <fps>23.976</fps>

            <refresh>24</refresh>

        </override>

    </adjustrefreshrate>

</video>

Code:
<video>

    <adjustrefreshrate>

        <override>

            <fps>23.976</fps>

            <refresh>25</refresh>

        </override>

    </adjustrefreshrate>

</video>

While the following setting works but with jerky playback (and audio pitched up more than 4%, which is logical)

Code:
<video>

    <adjustrefreshrate>

        <override>

            <fps>23.976</fps>

            <refresh>50</refresh>

        </override>

    </adjustrefreshrate>

</video>

And the following setting works but imply a 3:2 pulldown judder (the reason why I needed the "Adjust" & "Sync" settings...) :

Code:
<video>

    <adjustrefreshrate>

        <override>

            <fps>23.976</fps>

            <refresh>60</refresh>

        </override>

    </adjustrefreshrate>

</video>

When I try this setting (telling Kodi to chose the first refresh rate possible in the range), it displays a 50Hz refresh (with jerky playback and pitched audio mentionned above) :

Code:
<video>

    <adjustrefreshrate>

        <override>

            <fps>23.976</fps>

            <refreshmin>22.0</refreshmin>

            <refreshmax>51.0</refreshmax>

        </override>

    </adjustrefreshrate>

</video>

What I understand is that there is a conflict between Kodi and OSX about the ability to force a refresh rate of the TV under 50Hz.

I have not found anything about a Yosemite update that breaks refresh rate handling under 50Hz, though.

Anyone in the same case ?… Please, help…

try the latest nightly:

http://mirrors.xbmc.org/nightlies/osx/x86_64/

should solve your problem.

Thank you for your answer.
I've just tried today's nightly, with empty advancedsettings, crashes when I try to read a 23.976 file… (freezes, I have to force quit)
Do I paste my log file ?

neurosis13 · 2015-05-15, 00:02

you can post a log file but i think something is wrong inside your kodi settings, playback of a 23.976 file shouldn't crash or freeze your system.

what i would do is:

disable your tv out or better pull the hdmi cable out for testing purpose and retry.

If that doesn't work delete your guisettings.xml file (backup first) and restart the latest nightly kodi.

Ok, some new elements.

I deleted every files related to XBMC and Kodi on my Mac (I have a backup of my video database elsewhere), and proceeded to a clean install of the latest nightly.

1/
With the HDMI cable unplugged to test directly on the iMac's screen :

a/
"Adjust display refresh rate" Off
"Sync playback to display" Off
Result :

Framerate is continually oscillating between 23.81 and 24.04.

b/
"Adjust display refresh rate" On start/stop
"Sync playback to display" Off
Result :

No difference with above result.

c/
"Adjust display refresh rate" On start/stop
"Sync playback to display" On
Result :

While I should have a stable 24Hz refresh rate (OSX handling of 23.976, the behaviour I was used to in XBMC 13.2), I have a native 60Hz refresh, and the video playback is really choppy.

d/
"Adjust display refresh rate" Off
"Sync playback to display" On
Result :

No difference with above result.

2/
With the HDMI cable plugged to my TV to test on my TV screen (Video output : Full Screen #2 ; Audio output : HDMI) :

a/
"Adjust display refresh rate" Off
"Sync playback to display" Off
Result :

Stable 24fps framerate, but clearly visible 3:2 judder.

b/
"Adjust display refresh rate" On start/stop
"Sync playback to display" Off
Result :

Framerate is continually oscillating between 23.41 and 24.39, visible judder every ≈ 41 seconds (23.976 / 24 OSX bug).

c/
"Adjust display refresh rate" On start/stop
"Sync playback to display" On
Result :
Freeze ! I have to force quit Kodi. Here are the lines of log file after the moment I launched the video :

d/
"Adjust display refresh rate" Off
"Sync playback to display" On
Result :

A framerate of 30, and a refresh rate of 50 Huh

Playback is choppy, and acceleration is quite visible.

When plugged to my TV (the everyday configuration I need), only results a and b make sense for me in regards with the settings, but one implies 3:2 pulldown judder, and the other implies the ≈ 41 seconds frame skip due to OSX bad handling of 23.976fps. (These annoyances were the reason why I needed XBMC, and was satisfied with the 13.2 before my configuration begun to f*ck up…)

The only setting that would deal with both these annoyances are "Adjust display refresh rate" (to have my TV refresh rate to 24), and "Sync playback to display" (to keep audio synced with video when video is sped up from 23.976 to 24 by OSX). And these settings together make my Kodi freeze…

Is it possible that it comes from a recent Yosemite update ? Any user with an equivalent configuration who faces the same problem ?

**Memphiz** · (This post was last modified: 2015-05-15, 19:58 by Memphiz.)

Please post the full debug log (wiki) to pastebin.com and put the link in here. Also what are your audio settings in Kodi?

cybergrunge · (This post was last modified: 2015-05-15, 22:10 by cybergrunge.)

Thank you for your answer.

Here is the link to the debug log file : http://pastebin.com/W4R3GxAk (case 2/ c/ that results in a freeze)

I use the HDMI audio output, which is plugged into my TV (audio passes through the TV, and is output by toslink to a DAC).

juramusger · (This post was last modified: 2015-05-15, 22:23 by juramusger.)

It may be another thing entirely but your description reminded me of what I experienced. I immediately thought of it because of the two screens and the crash with 23,976hz files.
I posted about it here a couple of weeks ago.
If you have the time and the files, try 50p and 60i video, they behave differently on my system

I also use 2 ch over HDMI, but I do use passthrough (AC3 and DTS)
Edit: Oh, and I always use "adjust" and "sync" and didn't even check without, as for the reasons you mentioned both are a must on OSX.

**Memphiz** · 2015-05-15, 23:55

I really wonder how it should resample audio when you have passthrough enabled. Does disable passthrough make a change? Also we are on to something which might be related to your problem - will post a test build once the approach is clear...

cybergrunge · 2015-05-16, 14:07

Precision : I have not enabled audio passthrough in Kodi, digital audio is sent (resampled if option checked) via HDMI. The passthrough is on my TV side, which does not process the digital signal but outputs it instead via toslink (to an externat DAC plugged to my stereo amplifier).

I hope the something you're on will eventually fix my problem, when do you think this will be available on nightly ?

**Memphiz** · 2015-05-16, 15:22

please try

and report back

cybergrunge · (This post was last modified: 2015-05-16, 17:28 by cybergrunge.)

Thank you Memphiz. Smile

The fix seems to be effective, no freeze when launching, the "O-key" info are quite good (refresh 24, speed +0.100%, framerate constantly oscillating between 23.41 and 24.39 though, is that normal ?)

I think I saw some skips on the first test I ran (those of the OSX 24Hz bug), but not on the two following, and I know tired eyes can play some tricks…
Here is the debug log of one "clear" test, if it is of any use for you : http://pastebin.com/f40VtgqV
I always launch the beginning of Elysium to test frame skips and judder, as there are several minutes of travelling sequences (one of the few qualities of this movie Big Grin

), but I'll take a couple of days to test this build out with different files. I'll post my conclusions here.

Let me know if this fix is merged to a future nightly, so I can test it also.

Brian O'Blivion · 2015-05-17, 01:18

I've had the exact same experience as what cybergrunge described in his original post, including having to stay on 13.2 to keep sync working. I reported it in this thread, but the developers seemed to think it was a hardware/firmware problem. I'd just like to say that the test build fixed it for me too Smile

FernetMenta · 2015-05-17, 16:35

Quote:framerate constantly oscillating between 23.41 and 24.39

just ignore this silly value. I tried to remove it but there was too much protest from people who did not even know what this value is about.

juramusger · (This post was last modified: 2015-05-17, 20:04 by juramusger.)

fixed for me as well, thank you Memphiz!

I have no clue, but it works.
Way back, I think in version 12 or so I heard a little sound clipping every couple of seconds as if the bitstream needed to drop frames to keep in sync. That made total sense to me as I had "drop/dupe" selected. It also did when I selected "resample", which also made sense because if I understand correctly it should revert to "drop/dupe" for passthrough anyway. But it's been good for a long while now.
I would also love to know how it works, but for the most part I am pretty happy it does.
