Update:

I am new to Kodi, but since I have a big collection of xvids , i hope i can help as I managed to compare some of the files which play unsynced audio.

NOT ALL xvids have the same problem, but with media info I managed to pinpoint the problem for the videos with unsynced audio, and it seems all of then are encoded with the Simple@L5 xvideo profile as its called in the encoding configuration dialog of the Xvid codec.

For example Video1 Is healthy and the audio is synced .

Also another information that might help is that 90% of the files i checked have in Format Settings : CUSTOM/MATRIX.
I guess some bad boys encoders messed with the default settings of xvid writing libary.

Not all XVID -with profile Advanced Simple@L5 have the same problem. Some of them play fine.
But 100% of the files with Custom/Matrix format settings based on Simple@L5 reproduce the problem.

Also among the 100 files i checked i found also 4 DVIX encoded files With CUSTOM/Matrix format settings which are also unsynced.

I have the XF9005 Sony. For me going back to 17.6 solves the sync issue but its not ideal. Why? Has anyone noticed the reduced quality of the videos?
SOnys x1 Processor is very good and it does great upscaling with Hardware ACCel. enabled. So i suspect that 17.6 version uses the software encoder for those type of files and as a result plays the movie with not such great upscaling and a 15% maybe even 20% quality loss
The more powerful processor your tv has, and the bigger your tv is, then the more noticable is the difference from one version to the other.

Then i tried to re-encode only the sound of the file leaving the video untouched and voila what a surprise!

With avidemux it takes only 1-2 minutes for a 800mb file to -re-encode the sound to AC3(i picked it accidentally) and the audio with the picture is suddenly synced in the new file.

I intend to re-encode the sound all the videos which have that issue now since as the rumors say there are not gonna be much changes in 19xxx....

Encoding the audio only is much easier and obviously less time consuming.

I dont know why Kodi does this. If its the audio codec or the hardware acceleration, or just sony in combination with the latestr KOdi, but i hope all these information will help the developers.

Thanks, DaVu - your comments are almost (!) as helpful as an actual fix. As users, we can appreciate the massive effort that's gone into Kodi.

Nonetheless, I have to point out several things:

1. "Free" doesn't mean that we users have no investment in the software. On the contrary, I have invested probably a dozen or more hours attempting to work around the recent Xvid bug. And I've spent many, many hours configuring Kodi to be easy for other members of my family. We've come to rely on Kodi for many purposes.

2. Communication is essential. It would have been great if Kodi 18.3 (or whatever we're up to) had flashed a message stating that bug fixes were being delayed. At least we'd have known where we stood.

3. It's incomprehensible that such a basic thing as Xvid playback was working in Kodi 17 but broken in Kodi 18. It took real effort to do this. I'd still love to know why the breaking change couldn't easily be rolled back.

4. If you want to start charging for Kodi, sign me up. I use Kodi because it's the best application of its kind, not because it's the cheapest. I'd be very happy to pay a substantial price for what Kodi gives me. Especially if that would ensure bug fixes and feature improvements for the future.

Hi, I'm newbie here (not usin xmbc, kodi, etc..)
Why is this marked as "solved"?
I couldn't read an answer that solves the issues, not al least for Android users on smar TVs
Thanks in advance for your excellent work all thes years!

The thread is solved because that condition will not be fixed.

The Kodi team understandably doesn't want to downgrade to an older FFMPEG version anymore. And then we would also get problems with the playback of h.265 videos, which were not smoothly playable with the older FFMPEG version of Kodi 17.6. At least not on my Sony Android TVs.

But it's a pity that they don't work on the decoderfilter.xml "problem" anymore, because with it you could force the software decoding of old MPEG4 videos, but in newer versions a bug has crept in, which doesn't allow a smooth playback anymore. In the first Kodi builds with decoderfilter.xml the playback was still absolutely smooth with older XVIDs & forced MPEG4 software decoding via decoderfilter.xml.

But long speech short sense -> thread is solved Smile

HD files downloaded from the onlineTVrecorder platform are coded as AVI files and have the audio sync problem. So the issue is alive with current files. I use VLC now which is a much better player than the built-in kodi player and it has no problems with audio sync.

jon12345 · 2020-07-15, 13:27

I'm trying to understand the technical details of this issue. Is it the newer version of FFMPEG that exposes some bug in Mediacodec hardware decoding?
Why did the old FFMPEG version not expose this?

Also - why is VLC not affected by this issue?

macmpi · 2020-07-15, 19:22

@rainman74 It did follow your kind suggestion about pushing via adb /sdcard/Android/data/org.xbmc.kodi/files/.kodi/userdata/playercorefactory.xml onto my Sony TV XF9005.

xml:
<playercorefactory>



<players>

    <player name="VLC" type="ExternalPlayer" audio="true" video="true">

        <filename>org.videolan.vlc</filename>

        <args>"{1}"</args>

        <hidexbmc>true</hidexbmc>

        <hideconsole>true</hideconsole>

        <playcountminimumtime>120</playcountminimumtime>

    </player>

</players>

<rules name="system rules">

    <rule video="true" videocodec="xvid|divx|div3|div4|div5|dx50" player="VLC"/>

</rules>



</playercorefactory>

I also installed VLC which does play my files fine (are on NFS share, XVID-mp3).
However, despite playercorefactory.xml file, Kodi 18.7 still seems to play my file with HW mediaplayer and not calling VLC.
Any further hint?
Thanks.

PS: BTW I did not check if a default playercorefactory.xml file existed in userdata before adb push: should I have saved anything before?

vanhux · 2020-07-16, 23:05

Any updates on this one ?
I truly believe that it cannot be do much work to get it fixed once it was working in the past.

And the only result of not fixing it will be slow movement of users to another software.

Cmon guys - I remember times where there was not even one person saying bad word about Kodi. Look now.

Could be...I have two Android TV's, one an expensive bravia, and a cheap Element TV. Both have issues with audio sink, but with different files. I will look closer as to which they are.

I converted the avi files to h264/AC3 mkv's and no more out of sync issues

What did you use? ffmpeg?

No, you do not have to save anything.

Re-encoding only audio is not enough for all files.

I recommend a complete conversion:

Code:
for /R %I in (*.avi) do ffmpeg -i "%I" -map 0:v? -vcodec h264_nvenc -preset slow -profile:v high -level:v 3.1 -crf 18 -map 0:a? -acodec aac -b:a 192k "%~nI.mkv"

I guess +1 more for this issue. Just bought an Insignia Fire TV and having this problem, along with not being able to play some files at all (all exact same codecs). Probably specific to the Fire TV itself because all other Firesticks around the house play the files fine, with the occasional sync issue. Not looking for help or anything so won't post a log, but basically the entire log is just this.
