makemkv hangs, makemkvcon at 100%

Post by nordwand »

Hi all

MakeMKV v1.18.3 (new compiled)
Registered user.
Arch Linux up to date

I am trying to rip a BD, but the main MakeMKV window has "Scanning CD-ROM devices" at 100% and hangs there.
There is a process "makemkvcon" that eats 100% CPU time, which seems what the frontend is waiting for.

I can confirm that with 1.18.3 on Windows, with the same BD reader and BD disk, there are no issues.

Any ideas?

Is your sg kernel module loaded?

You can load it for the current session via modprobe:

Code: Select all

sudo modprobe sg
