I hope I am posting this in the appropriate forum.
I performed an upgrade
sudo pacman -Syu on 4/28/21 and later noticed that my installation of comskip https://github.com/erikkaashoek/Comskip was failing with a segmentation fault. I looked at the recent updates and noted that ffmpeg had been upgraded to ffmpeg-2:4.4-1. I downgraded to the prior ffmpeg-2:4.3.2-6 using
sudo pacman -U /var/cache/pacman/pkg/ffmpeg-2:4.3.2-6-x86_64.pkg.tar.zstComskip is now processing files without segmentation faults.
I'm not sure what other information to include or if the upgrade affects anything else. Let me know if I need to provide other info.
Best,
Craig

You need to rebuild comskip.

I did a rebuild of comskip with the same results....segmentation fault using ffmpeg:2-4.4-1 but completes with ffmpeg:2-4.3-6

Did you rebuild it when you had ffmpeg 4.4 installed?
Apparently the 4.3->4.4 update did not break ABI, so it did not require package rebuilds.
In this case I guess it points to a bug in comskip, or in ffmpeg itself.

I found the problem isn't with ffmpeg or comskip but with my several year old comskip.ini. I ran comskip without comskip.ini and it worked though not very good at finding commercials with the default setup. I have been using the same comskip.ini for at least 2 years now with no problems. After some experimenting I discovered the problem, although I'm not really sure why it became a problem. My new comskip.ini is my old comskip.ini with all the comments removed. Previously I had comments next to the tuning parameter to help remember what each parameter did and list options.
Thanks for the help and sorry for the wild goose chase,
Craig
