AVI audio is out of sync since 18.0 - rainman74 - 2019-03-18

Update: Tested with Kodi v20.4 and the problem no longer occurs. The audio is now played correctly.

Problem:
  • Audio output is no longer synchronized to the video for AVI files (Xvid/MPEG-4 ASP)
  • Tested with 18.0, 18.1 and 18.2 RC
  • Not affected are AVC and HEVC videos in MP4 or MKV containers

Test environment:
  • Android ARM
  • Sony Bravia TV Oreo - Kodi 18.x - audio is not in sync
  • Sony Bravia TV Oreo - Kodi 17.6 - audio is in sync

Last working version:
  • kodi-17.6-Leia-armeabi-v7a.apk
  • The exact newer build where it doesn't work anymore is not known

I'm also having sync issues and had to go to SPMC 17.6a... but mine are with AC3 Dolby Digital.

Thank you... mine too

Can you please provide me with a test video where this occurs?

Mine too. With a half-hour AVI, I get about 10 minutes in and video jerks around a bit, then audio falls horribly out of sync. Stopping and resuming from the bookmark fixes the problem, at least temporarily. Looks like some kind of buffer issue.

These are old Xvid AVIs, probably made years ago with AutoGK. Never caused a problem before, in a wide variety of hardware and software players.

It's exactly the same for me! Minix U9-H with the latest Kodi v18. There's been no issues with my old WD TV SMP, and also on PC they play OK.

I have the same issue on my 2016 Sony Android TV with Kodi 18. 
It seems to be an issue specifically with Xvid files with MP3 audio. It seems that Kodi is detecting the framerate of some of these videos as 30 FPS regardless of underlying content while playing the audio at the original rate. As a result UK shows get out of sync almost instantly (25FPS to 30FPS), whereas US shows with the 29.97 FPS deviate more slowly. These files were working fine on v17. Testing them on my desktop copy of Kodi does not exhibit these issues
Annoyingly, it's not even all Xvid / MP3 files.

This file is fine:

I was hoping to retire my WD Live Hub, but it looks like I have to keep it to play the older files.
All the older family videos, priceless...

If you're using an Android or Linux box, don't forget VLC player. It's a pain compared to Kodi, on a TV setup, but it's not a bad solution until the Kodi bug gets ironed out.

Use CoreELEC Kodi Leia running from a Class 10 U1 microSDHC card.
With (AMLogic) CoreELEC, the OS, Linux Kernel and Kodi have been optimised for older mpeg2, Xvid/mpeg4 and VC-1 video playback:

The problem with ALL Android platforms is the Kodi developers cannot bug bust the OS or the Linux Kernel to provide such support for old video compression standards.

You get what you are given from the media player vendor.

That can't be the main reason, because the same SD files under KODI 17 with SW decoding are jerk-free and now with KODI 18 with the decoder filter also jerk with SW decoding! And both on a Fire TV Stick with Android 5 and on a Sony Android TV with Android 8. Strangely enough, the videos then play smoothly with SW decoding on the devices with activated debug overlay.

As a matter of fact, I still take video with a camera that uses 720p

Family videos, but still.. need to be able to watch them.

By all means, keep it. I am terribly disappointed with Kodi/Android on theoretically one of the best boxes. With WD, everything supported is played without slightest problems.

RE: AVI audio is out of sync since 18.0 - gamish - 2019-06-12

Blaming Android runs counter to the obvious facts. My previous version of Kodi played AVIs just fine; the most recent builds, on the exact same box, do not. Moreover, playing an antiquated format like Xvid/AVI should present no challenge on today's octa-core devices. (I did try putting an old Xvid in an MKV container. Doesn't help.)

This is clearly a Kodi issue. Maybe a 'minor' system-wide change that had unintended consequences? Dunno... but I sure wish they'd fix it. There's a vast base of older AVI files out there.
