I used cannot in the sense that I am not allowed to. ;-)

I almost never have this. (If I remember well, only with videos
created with ffmpeg. Sometimes it started on a negative timestamp
instead of 00:00:00.)

Looking at the -to you would expect 7:22, but when I just play it, it
ends at 7:21.

I am using Debian (stable). That always uses older versions.
I could look if there is a newer version in backports.
