I think it has to do with MLT, but I just don't know where to start.

Console output is useless to debug crashes. Post a backtrace.

redshoe · 2023-10-24 19:45:12

According to the library maintainer on Github, MLT version 7.20.0 may be the problem due to changed API.

So, in the meantime, should I report this as a bug?

seth · 2023-10-24 20:08:36

You did - for reference: https://github.com/jliljebl/flowblade/issues/1129
Did you try to downgrade MLT to see whether that's the cause?

Igorjan94 · 2023-11-02 05:30:21

Yes, it's the cause. Downgraded mlt to mlt-7.18.0-4-x86_64 and it runs OK
