Hello,

I have a 1080p movie, which *plays smoothly* in WMP or KMPlayer.

When the same movie is played via XBMC, the playback stutters / is jerky (play-pause-play-pause....).

I've tried various setting in 'System -> Videos'. Also tried other skins, to no avail.

Its only with this Movie. All other 1080p movies play fine in XBMC with the same settings.

Can anyone tell me what's going on ?

Thanks !

Run MediaInfo (wiki) on the file and tell us what it says. Also try to get a debug log (wiki) of when you play the file.

Hope it has the required info.

Thanks.

I can't see anything obvious in the info. Can you post a debug log. Enable debug logging from System settings, System, Debugging, and restart XBMC then wait a minute or two for all the startup tasks to finish. Now play the film for a minute or so or until it gets jerky. Stop the film then close XBMC.

Open the debug log by pressing Windows-R and in the Run dialog type:

Code:

"%appdata%\xbmc\xbmc.log"

(including the quotes). Click OK and the log should open in Notepad. Copy and paste the log into http://pastebin.com/ and post the link it gives you here.

OK, here is the debug log for the movie:

Please take a look.

Thanks for your help !

Hello,

As instructed, I have posted the debug log. (See my post above for link)

Could anyone take a look at it please ?

Thanks !

To me it looks like there's scrapping still running in the background while you're playing the movie, maybe that's why your playback stutters. That's just a guess, I'm no expert on this. Do you have automatic library scan activated for every startup of xbmc? If so, try disabling that.

[roycejp]

Yes I have enabled automatically scanning at startup, but that is not the cause.

I waited till the scraping finished, and then tried to play the movie, but the problem still occurred.

Besides, other 1080p movies play fine even with scanning going on.

Thanks!

This is definitely an odd issues. If your feeling up to it try a nightly. Install it into a separate folder and run it in portable mode to not mess up your current XBMC profile. There have been some ffmpeg changes that may resolve this issue.
