I was able to compile and run, thank you. I am currently using X11 and not Wayland.

The problem is the lrelease (qtchooser) executable which does not detect my QT6 installation even the right executable is here. I have to check my installation.

QT_SELECT=qt6 lrelease -version
lrelease: could not find a Qt installation of 'qt6'

/usr/lib/qt6/bin/lrelease -version
lrelease version 6.4.2


Great to know, thank you!

Quote from: grolandi on June 25, 2026, 02:51:22 AMDoes Avidemux use any portion of ffmpeg that contains the new pixelsmash vulnerability?

Avidemux doesn't enable MagicYUV decoder, the one containing this particular vuln, in its bundled libavcodec, therefore the answer is "No".

Does Avidemux use any portion of ffmpeg that contains the new pixelsmash vulnerability?

If so, what are the plans to patch Avidemux?

Thank you.

Build with Qt5 should work now, please pull the latest changes and retry. You may need to explicitly request xcb (XWayland) on Wayland, e.g. by passing

-platform xcb
to Avidemux executable.

Qt 6.4.2 in Bookworm may be too old, in doubt please provide the actual build error (warnings about redefining definitions are unrelated).

This is the closest topic sorry if it is the wrong one. I tried to compile with QT5 on Debian 12 and it failed. Then installed QT6 packages, including qt6-base-private-dev package, and tried to compile with QT6 and it failed again. It was working with QT5, my last successfully compiled version is 260411_20b2688a961-fflibs 7.0.2. QT6 has issues (warnings?) with QT_TR_NOOP and QT_TRANSLATE_NOOP redefining, QT5 has issue (error) with "avidemux/qt4/ADM_userInterfaces/ADM_gui/T_preview.cpp:312:34: error: 'class QApplication' has no member named 'nativeInterface'". Both compile stopped and generated no executable.

So something happened after commit 20b2688. Any idea how to solve this issue?

Is FLAC audio output support a possibility for a future release? For myself, and I believe many others, it would be a great option to have if possible. plz&thx!

@eumagga0x2a Why do the current nightly builds no longer support NVENC? This unfortunately renders them unusable for me.

On Linux with X11, hw accelerated video encoding via VA-API / libva was available with all graphics cards supporting this interface, i.e. AMD and Intel. Unfortunately, with the switch of all major desktop environments and thus Linux distributions to Wayland this is the thing of the past. NVIDIA with NVENC and all other goodies still works fine via XWayland, but not the libva stuff (Avidemux natively on Wayland is even more limited).

On Windows: no assessment done yet, much less work started. "Never" may be incorrect, but "not this year" is more than likely.

Doch, auch wenn sich die Symptome ähneln, haben die beiden Themen wenig miteinander zu tun.

Diese Datei wird in einem Avidemux vom aktuellen git master (was irgendwann 2.8.2 werden soll) einwandfrei als MP3 erkannt und als externe Audiospur akzeptiert. Avidemux 2.8.1 ist schlicht sehr, sehr alt.
