TheSwissKnife Wrote:1. There is no such thing as "perfect video timing with scaler/TV etc". If you are saying that your modeline is accepted happily as a mode 32 23.976p signal then fine - but there is a large range of modelines that would give the same effect, and most will have different refresh rate. More importantly, none of them will exactly match your audio chip clock rate, but you might be close enough to only drift slowly so that the delta is less than an audio or video frame over a few hours. Please take the time to understand this fundamental point.

2. WITHOUT audio AND WITH subtitle works or not? - you have not made this clear.

3. With sync method audio drop/dupe (not dude), and no subtitles do you have VIDEO stutter or not? You don't make it clear the way you write. I am not interested in the fact you get audio stutter at this stage - so don't mention at this stage. If you get video stutter please confirm that this happens without the codec screen up and if there is anything in the debug log around that time (with a few seconds). How many stutters do you see through the sample on average? The way I remember the standard xbmc code is that you need a 100ms delta between audio pts and clock for it to move the clock in drop/dupe mode so if this is happening with good timecodes then you really have a big problem with the audio driving on your system.

I will try sample later - please (re-)post the link to the version that you are now using after remux.

deuch Wrote:All my video system works perfectly fine.
I'm understanding the "problem" of audio and video sync with multiple clocks.
But why other software works with the same hardware and the same file ? Does XBMC choose a bad solution to handle this sync ? It's the first time that i've this kind of issue with a soft (or a hardware). I can easily compare because i've a lot a NMT and different PC with different software. It's the first time that i've to tweak and made test just to be able to play a video file. So yes i'm a little angry because i can not understand why this kind of probleam can appear in 21st.

Quote:I can say that subtitles do not provide stutter even with or without audio (i'm using a another font than arial.ttf). To not have stutter, i've to remove the audio track.

Quote:I've stutter without A/V sync. After remuxing the file, i've got stutter gain. Less than before, but it still present (with audio and subtitles and no A/V).

I can test with A/V but it help a bit, but far from perfect.

bibi Wrote:What i still need to try :

- Use working custom modeline (i tried with a custom modeline at 23.976 from a web calculator but my TV indicates me that it's not a valid format ; but i'm pretty sure it's valid cause i get it with good refresh rate (horizontal and vertical) and good pixel clock. Anyway when i try the modeline from my EDID but with a manual configuration (NOEdidmode... in xorg.conf) it doesn't work as well .

- remux files with good timestamp, video are on my server and i can't use a gui for mkvmerge cause my nxserver cant deport the gui and i am too lazy to use console (if you have a script, i looked for one on the web but couldn't get a script without weird dependances (i'm on arch) -> i'm gonna test your files this week-end (Deutch)

TheSwissKnife Wrote:I understand why you bring other players into the subject as sometimes it helps to know that things could work better, but often it does not help to keep mentioning it - there are architectural differences and design choices that mean comparisons are sometimes unhelpful.

Robotica Wrote:Just know that XBMC's DVDPlayer is behind in development compared to most known players (like MPC, VLC, Mplayer, etc.). Sometimes due to architecture, sometimes due to interest (VAAPI and intel/amd hardware) or choices (following FFMPEG). And off course the number of devs for eacht player is different.

In the end it doesn't matter that much.

Even the remuxed file provides some stutter (during the travelling on the pyramid and sometimes in the tunnel after a another play)

plays 1000% ok no dropped frames no jerky video no lack of audio sync, its just smoother than a babys bottom... nice piece of anime, not that I usually or often watch anime.

X3lectric Wrote:I use XBMClive (xbmcbuntu install) with everything official XBMC and I compile XBMC from GIT source, patches and other fixes on my signature or blog or has been posted on these forums. Its Lucid based or Ubuntu 10.04, Nvidia drivers, 275.09.07 vdpau acceleration.

deuch Wrote:So now, what is the magic trick to have the same result ? Because i don't care about the origin of the problem, i want to have a solution to my (and not only me) problem.

Because i'm very surprised that you don't have problem with this file if you are using the official XBMC (witout Audio Engine ?).

So if you have a perfect setup, maybe it will be a good thing to post a HOW-TO to achieve the same result as yours.
