Selur's Little Message Board

That's extremely strange, since I hadn't touched any experimental settings and typical installation over previous Hybrid version gave me same results

Just to be sure: You did check that no anti virus scanner, firewall or similar is running amok and slowing the muxing down,... right?

Ok, I'm done. It stopped again... 
Now it won't even start or stop at 1% !!!
It seems like a FFV1 issue tho: if I passthrough video, mkvmerge does its job

UPD: no f*king way! It depends on the GOP size parameter of FFV1! With GOP = 1000 it stops every time, even on 1min video

I can reproduce that.
=> seems like a bug in mkvmerge
best report it to: https://gitlab.com/mbunkus/mkvtoolnix/-/issues/
(have to go to bed now, if it helps I can report it tomorrow for you there)

Ah, I forgot they use GitLab... I will try again tomorrow (today, actually ) just to be sure that this problem is reproducable every time

Let me know how it goes and whether I should create an issue report or whether you filed one.
