Avidemux Forum

The service of providing official cross-compiled nightly builds was a courtesy of the project maintainer as any decision about resuming or not resuming it in the future. Cross-compiling Avidemux is well documented and essentially trivial to not depend on supply of official builds.

Should be fixed by x264/qt: fix threads combo box index off-by-one on upload to configuration dialog, thank you for your report.

Any ETA on next cross-compiled build release? Because latest is from 2024. I prefer a version that can run on Win7 too, and does not have overbloated installer...

Very simple bug - set your video codec to x264, open "Configure", change the 'threads' amount to something other than "Auto" and click OK. Then open "Configure" again and observe that the 'thread' settings is now set to one value less.

This bug exists on both Linux and Windows, but the nightly Linux builds don't want to launch on the various live Linux ISO distros I tested with (Xubuntu, openSUSE tumbleweed Xfce, Linux Mint Xfce).

Video demonstration using the live ISO of Hiren's BootCD PE for easy reproduction:

Now admittedly this bug has been around since at least the stable release of Avidemux 2.8.1 but I didn't report it at the time since I was a bit late to updating from the previous version, and therefore I figured "the next version should be out soon anyway and I'll double-check it then".

...it's now like 3 years later and v2.8.1 is still the newest stable release, but I realized that the website's downloads page has a link to nightly builds that I was able to subsequently use to test and confirm that, yes, this bug still exists (DISCLAIMER: being a Linux user, I'm used to downloading Avidemux via my distro's software manager which includes flatpaks like Avidemux - I haven't had to go to Avidemux's "downloads" page since my Windows 7 days.

Perhaps D3D12on7 could come into play?

I have lots of MKV files with soft-embedded subtitles. I need to cut out random parts of the videos but need to keep the subtitles. I absolutely love Avidemux's ability to cut my files and would be willing to pay a couple hundred dollars for a lifetime license or a perpetual monthly fee of say $5 if you add the ability to handle subs. Is this feature on your roadmap? LosslessCut does this but no matter what I try, I can't get a perfect cut when the MKV segments are merged back together. I always end up with this weird SPLIT second glitch at the spots I removed despite cutting on key frames. When I chop the same sections with Avidemux, they're perfect.

2nd question/request. When I import my MKVs into Avidemux, they'll often have multiple audio tracks. Example: English AC3, English DTS, Director Commentary, etc. When I chop up an MKV file, the output file lists all those individual audio tracks as: Track 1 [English], Track 2 [English], Track 3 [English] etc. When Avidemux is saving the new file, can it retain the original names for the audio tracks?

Thank you

Mit Avidemux wird es schwierig, ich würde da schauen :

Das meint nicht, dass die Lösung trivial ist.

@fabian3357,
für die Synchronität werden Haltepunkte festgelegt.
Mit anderen Worten : Audio von Video 1 + Video von Video 2 mit exakter gleicher Videolänge kann synchron sein, muss es aber nicht.
Manchmal ist die Verschiebung nur gering, und mit Avidemux + Audio-Offset kann man das Video synchronisieren, bis zur nächsten Asynchronität, das Video splitten usw.. Am Ende wieder cat mit Avidemux.

Vielleicht kann man das auch auf SAT übertragen. Panasonic BD SAT receiver nehmen den TS-Stream 1:1 auf.
Mit allen key-frames, IDR-frames usw..
2 Vermutungen :
1. ARD + Co senden via SAT oder DVB-T2 das "gleiche".
2. Panasonic Recorder nehmen den TS-Stream unverändert auf.

Vielleicht ist es nur ein Recorder Problem ?!

I've gone back to X11 and it works fine.
