MakeMkvcon backup iso

[Dapsol]

Hi,

can the 'backup' option of makemkvcon be used on an .iso file? I can't get it to work, please advise

My goal is converting a blu-ray .iso file to something unencrypted so i can transcode it with handbrake-cli. I only have a console (no gui), using Debian wheezy.

Code: Select all

makemkvcon backup --decrypt iso:'/home/me/scripts/makeMkv/files/mydisc.iso' -r '/home/me/scripts/makeMkv/files2/'

Backup source must start with "disc:"

Handbrake CLI can work with MKV files, which would be decrypted. I use it that way all the time. You need to be using a "nightly build" version to deal with things like subtitles within the BD rip.

If you were hoping to preserve the menu structure by going with the backup option, handbrake isn't going to do that.

Thanks for explaining,

Okay so i need a nightly of Handbrake to handle the subtitles in blu-rays? that's bad news, i've been trying to compile Handbrake-cli (on Debian Wheezy) but couldn't get it to work, so eventually i installed by adding "deb http://www.deb-multimedia.org wheezy main non-free" to obtain the package from there.

if i run "HandBrakeCLI -u" it reports this version:
