While current MAT packer for TrueHD works really very well, I have found some rare cases (0.1%) that may produce non-compliant bitstream, especially related to seamless branching Blu-Ray sources (or resultant MKVs remuxes).

The new implementation is based on LAVFilters implementation with some optimizations and small changes. Then is totally different from current FFmpeg based implementation...

Omega Test Builds:

Android ARM64 (Shield):
kodi-20240516-9d1d4de1-mat-packer-Omega-arm64-v8a.apk

Android ARM:
kodi-20240516-9d1d4de1-mat-packer-Omega-armeabi-v7a.apk

Windows x64:
KodiSetup-20240516-9d1d4de1-mat-packer-Omega-x64.exe


Should be more robust especially handling sources with stream discontinuities or bad/rare/missing timestamps (to some extent of course).

May (or may not) fix some rare remaining dropouts/cuts on some specific streams...

These builds are Omega v21.0 based, then can be installed safety on top of current Omega release and also you can reinstall the official version on top of these to return to previous state (if necessary).


For those interested, it also includes much more information at the debug log level e.g.:

Code:

2024-04-14 17:31:16.198 T:21568 warning <general>: CPackerMAT::WritePadding: a large padding block of 247968 bytes is required due to unusual timestamps

Code:

2024-04-14 17:31:16.298 T:21568 warning <general>: CPackerMAT::PackTrueHD: detected a stream discontinuity -> output timing expected: 56504, found: 60344

Code:

Hello,

Using adbLink connect to your device.
Select Uninstall APK, select org.xbmc.kodi - making sure to tick -k (keep app data) - and uninstall it.
Reboot your device.
Reconnect adbLink, select Install APK and select the downloaded version of Kodi you want to install.

Thank you, jogal! I have indeed noticed that there can still be a small dropout in TrueHD, though it's rare.
Installed the test build and so far so good, I'll make another post here if I encounter any issues.

Thank you jogal!
I have tested but unfortunatelly same hiccups after some time. My setup is Shield 2019 - soundbar Q990C  - QE65Q67TAUXXH.

Where is your Debug Log?

my debug logs:

Your logs have no occurrence of term CPackerMAT:: then you are not playing any media file or any related to TrueHD passthrough audio

Hello jogal,

Whatever your issue is has nothing to do with the Packer. You play btw. Dolby DD+ - this guy here:

script.module.slyguy - RESPONSE OUT: https://cmaf.cf.eu.hbomaxcdn.com/videos/...07/v17.mp4 (206)

seems to highjack your mainloop very often. No idea what this is.

[kolololop]

Thx fritsch

And this guy:
warning <general>: ActiveAE - large audio sync error:
Whenevrr hiccups appears this line is written in log. Is there something to focus on - uninstall some addons or is it some audio -video sync general problem?

[fritsch]

It's an effect not a root - cause - fix your script and check if problem is fine.

I have no idea what you are doing or what you are playing:
2024-04-15 18:06:49.714 T:21115 info <general>: VideoPlayer::OpenFile: videodb://movies/titles/546?xsp=%7b%22limit%22%3a50%2c%22order%22%3a%7b%22direction%22%3a%22descending%22%2c%22ignorefolders%22%3a0%2c%22method%22%3a%22dateadded%22%7d%2c%22rules%22%3a%7b%22and%22%3a%5b%7b%22field%22%3a%22playcount%22%2c%22operator%22%3a%22is%22%2c%22value%22%3a%5b%220%22%5d%7d%5d%7d%2c%22type%22%3a%22movies%22%7d

But this file wherever it comes from has sever issues on the audio stream as kodi cannot even setup the stream type correctly. This is in no way related to this thread here.  Open your own thread and provide a proper sample / Debug Log where you play that from local file share, please.

Other than that: No TrueHD Mat Packer Sync issues in your logfile

@fritsh: thank for your analysis. I have made a clean install of this build and only few addons installed as well and so far no hiccups.
