Apart from hosting an ad service that served malware, and having their user database leaked more than once.

You can filter for manually installed packages yes.

But they do.

Example.

Why? mkvpropedit already does everything OP wants. No need to get ffmpeg involved.

Ubuntu had a general crackling issue introduced last year, an issue around a buffer size which I fixed by copying

/usr/share/pipewire/pipewire-pulse.conf

To ~/.config/pipewire

Uncomment

pulse.min.quantum = 128/48000

And increase to 512/48000. Restart.

systemctl --user restart wireplumber pipewire pipewire-pulse

Increase buffer until stuttering ends. Note this also introduces delay to audio.

Perhaps your issue is something similar? I wouldn’t blindly make these changes on your end, but maybe it’s something to search up on.
