Exactly, just wanted to post this as I saw your reply. The package is automatically installed only when building appImage in a Docker container so far. I wonder whether it could be made optional (i.e. package missing = disable all Wayland-related code), but for now it needs to be installed manually as you have done.

The package qt6-base-private-dev is not listed, nor installed as a dependency from the createDebFromSourceUbuntu.bash script.

It probably was installed in 25.10, Avidemux build without issue, but likely was removed by the upgrade to 26.04

Anyway installing the package solved the problem. I suggest adding it to the createDebFromSourceUbuntu.bash script so it gets installed when needed.

A big disclaimer: I don't have a working Ubuntu 26.04 on my PC yet (will probably create a VM as it doesn't seem to run on bare metal where gdm3 fails with NVIDIA driver installed – a combination where Fedora with RPM Fusion just works), but the list of files in qt6-base-private-dev

URL: https://packages.ubuntu.com/resolute/amd64/qt6-base-private-dev/filelist
includes the versioned directory. Will try to reproduce once I have got 26.04 running.

Sure I watched the video, explained you what was conceptionally wrong both in the video and in your question and provided you with a solution (or rather a workaround for a known limitation of Avidemux). I don't know whether the limitation of being unable to use a single internal or external audio track as a source for multiple output audio tracks has been introduced during the rewrite of the application between the 2.5.x generation and 2.6.x (with future 2.8.2 being a continuation of 2.6) or existed from the very beginning.

You can find all releases on SourceForge.

When looking at the logfile, at first the qt6 include paths are correctly found.

However later on, another cmake script apparently adds the qt6 version number to the end of that path. This version number directory does not exist on my system causing the qt6 build to fail.

Quote from: eumagga0x2a on May 18, 2026, 12:55:47 PMJust to use clear terminology: this is not about appending audio, which is impossible with Avidemux. This is about adding an external audio track. You would need to either copy the audio file to a different path or duplicate it (on *nix OSes: create a link to the original file under a different name) to be able to re-use it as another external audio track in Avidemux.

Thanks,  I found out in the youtube video that U decided Not to watch that it is version 2.5 - where can I get ?

I appreciate Avidemux.
However it lacks an important feature:

Avidemux does NOT keep all the EXIF header data fields when I re-encode an existing *.mp4 video into another *.mp4 video.
At least it does not copy the GPScoordinates from old to new video.

And the internal (!) Creation and LastModified Date

Why can't this super simple "keep EXIT" feature be implemented?

At least as user option for .mp4.

I guess 97% of all video conversions are from .mp4 to .mp4.
So a lot of users would profit from this function

Adding a feature to this program that while removing sequences the program knows where each subtitle timestamp is moved after edit without having to go into a srt text editor and changing all the timestamps based on when they're suppose to appear manually.   

In-tree build in a RAM disk using the script by Moshe Gottlieb (with build dependencies already installed and thus commented out in the script) works for me on my Mac mini M1, macOS 26.5.
