[PATCH] Global AV delay support via advancedsettings.xml
#76
Hmmmm... these are very worthwile observations. Can you guys pls continue to post your findings as to whether this seems to be just a DTS issue?
System: XBMC HTPC with HDMI WASAPI & AudioEngine - Denon AVR-3808CI - Denon DVD-5900 Universal Player - Denon DCM-27 CD-Changer
- Sony BDP-S580 Blu-Ray - X-Box 360 - Android tablet wireless remote - 7.1 Streem/Axiom/Velodyne Surround System
If I have been able to help feel free to add to my reputation +/- below - thanks!

I just tried playing a file with DD audio and one with DTS. Looking at the logs this is the only interesting piece I found:

Code:
19:26:16 T:2833431408   DEBUG: CDVDPlayerAudio:: synctype set to 0: clock feedback
19:26:16 T:2833431408   DEBUG: CDVDPlayerAudio - CDVDMsg::GENERAL_RESYNC(32000.000000, 1)
19:26:16 T:2833431408   DEBUG: CDVDPlayerAudio:: Discontinuity - was:152.902000, should be:0.000000, error:-152.902000

This happens on both files.

Edit: Here's (http://pastebin.com/raw.php?i=DrcQgvHr) a full partial log from when first playing a file with DD5.1 audio (which doesn't seem to lag, although I'm honestly not 100% certain) and a movie with DTS sound which IIRC lags.

Interesting info.

Great to see movement in this area.

My sync problems, however are codec agnostic.Huh

Every single 23.976 file has to have audio corrected, be it dts,acs or mono aac.

The patch works flawlessly in my setup.

In my case it seems the "discontinuity" value from the logs is the amount I need to delay the audio by. Of course it's practically impossible to be sure of that since nobody can hear a 1ms lag, but I usually set my delay to somewhere between 150 and 200 depending on source.

It's not unusual to see one Global Sync at the start of playback as well.

@DDDamian: have you seen this thread: http://forum.xbmc.org/showthread.php?tid=82896? I wonder if there's something similar going on. I guess I could try remuxing a file that lags to see if it makes it any better.

Hi negge - I do know some of the background to it, and the issues with the time stamps. It's part of the joy of so many rippers/muxers/recoders being out there that it's hit and miss as to whether the sync frames are correct.

If you have the patience to try remuxing some problematic files, please do. The more info on what works/what doesn't the better!

dude its all files, trust me i have spend 100s of hours beating my head against the wall on this one, save the brain cells (and your walls) no other apps do it (some might on files thatactually do have a timestamp problem but not to the consisitanty of xbmc this patch totally fixes it it just has a small bug about clearing its settings from memory so if you use it for anything other then 250ms 24htz oos bug its pointless but.... hey it works

Try this one, this is a single patch of all the commits in that pull: http://pastebin.com/rxjDVyL3. Or you can also get this single diff here: https://github.com/xbmc/xbmc/pull/713.diff

Also make sure to change your advancedsettings as described in the pull before testing. No new functionality in this patch, just a refactor. But it is always nice to have test reports.

Ok, I'll test this, but it's still not compiling for either :

I'm using the patches in openelec and it's prerty easy I have to drop this in a file and it compiles, butit chokes.

Trying to applythis directly on 1fef727 xbmc beta 3 main

Anyways, adding .diff rather than .patch to the url gives this :

Something in mainline is conflicting with the diff. Maybe something was changed in between that does not allow the patch to be applied directly to current master. You can just insert the rejected part manually.

You can't just insert the rejected part manually as far as I know it unpacks the source just runs the patches and aborts.

It's actually pretty slick and they've done a cool job of programming the build process.

Is your branch that different from master?

I did some testing the other day but I haven't found anything by looking at the logs as to what is causing the delay on some files and not on some others. I also tried remuxing a video that was known to have issues with the newest mkvmerge but it had no effect.

What someone should try:

1. Find a video clip that has delay issues.
2. Try any of the following:

* remux with different options in mkvmerge
* remuxing to a different container (like AVI)
* playing file without hardware acceleration (to rule out whether it's e.g. a VDPAU-specific issue)
* anything

There must be something that is causing this aside from the refresh rate change as I have a few videos which do not have any issues even though they play at 24fps.
