Avidemux Forum

Please start Avidemux (r241212), reproduce the crash and attach the entire log file (%localappdata%\avidemux\admlog.txt) to your reply, ZIP-compress it if it is too large.

The crash report suggests that Avidemux crashes in MPEG-PS demuxer which absolutely cannot be used in connection with HEVC as MPEG-PS is MPEG-1 / MPEG-2-only.

I wasn't able to look at the samples while they were available, sorry for that. Please provide the log first, thank you.

I tried to open the files in Avidemux 2.8.2 (241212_ce994de41a6-fflibs 7.0.2).

This time I got following error:

Please first verify that the problem persists with the latest known good nightly build which is currently r241212 before reporting issues, thank you.

Please disregard the almost entirely obsolete Wiki altogether, it reflects mainly the features of the long gone Avidemux 2.5.

I apologize if this has already been asked, but I did some searches and couldn't find anything useful.

The wiki mentions a tool to extract VobSubs by going to "Tools→VOB(nbsp)->(nbsp)VobSub".  However, the only thing I have under Tools is "Scripting Shell".  Where can I find the VobSub tool, and how do I add it to Avidemux?  (I'm using version 2.8.1.)

Great, thanks!

Should be fixed once wayland branch gets merged.

Found a fix for the abovementioned issue when looking at the buildscript from archlinux: the flag
CXXFLAGS+=" -fPIC" \needs to be added to bootStrap.bash

A patch like this should do it:
--- bootStrap.bash 2025-02-15 11:23:21.875284589 +0100
+++ /home/kgha/bootStrap.bash 2025-02-15 10:47:13.000000000 +0100

   fi
   pushd "${BUILDDIR}" >/dev/null

   cmake \

     $PKG \

Don't know if this is distro-specific, but if it's a general Linux issue maybe the flag should be added to bootStrap.bash?

Building (on slackware, qt6-6.8.2 installed) from latest git works fine using --enable-qt5, but when trying to build for qt6 I get the following error (from logbuildQt6):

What can I do to fix this?

Thank you so much for debugging the script for me. Obviously there are a few fundamentals missing from my knowledge.
