Since the commit of 320666 to FreeBSD-11 (and in head), avidemux is unstable. It dumps core fairly randomly on resumes after playback is paused. The dump points to a problem with qt4, but it is unlikely that there will be assistance from upstream as qt4 is no longer under development and is bitrotting rather badly.
The current port is badly out of date and shows multiple vulnerabilities. As a result, an update to the current release, 2.7, and moving to qt5 seems like an appropriate response. Upstream has supported qt5 for some time.
This is a particularly tricky port as it includes its own copy of ffmpeg and several other libraries. My efforts have, to this point, failed to get through the configure phase.
Can you try v2.7.0 at https://github.com/MikaelUrankar/avidemux/
(In reply to mikael.urankar from comment #1)
As I noted, 2.7.0 fails to configure due to not recognising FreeBSD's nasm. This is in the configuration of the internal ffmpeg.
Do you have a build log? It builds fine for me.

Log of failure in build attempt
I've been plying with getting some progress and understanding the very complex build system (with little luck), but still cannot get past the nasm issue. This is the error log from the build attempt.
I am still unable to find the test that produces this error somewhere in the guts of the ffmpeg build.
You need devel/yasm
(In reply to mikael.urankar from comment #5)
YEs, I have yasm. The problem is that the build in looking for nasm (which I also have installed) and the version string from the BSD NASM does not match any that they are looking for.
> pkg info yasm
Name : yasm
Version : 1.3.0
Installed on : Thu Aug 4 10:26:39 2016 PDT
Origin : devel/yasm
Updates to mesa and/or qt4 fix the issue without moving to 2.7.I still hope to get avidemux to build with qt5 and will open a new ticket when/if I have a patch ready.
