What to pass for input to scan DVD Disk with CLI

Post by iansul »

Description of problem or question:
Trying to understand what to pass for -i when scanning disk from command line. When I scan with the GUI, the activity log shows it scanning correctly, but when I try to scan with CLI it says "No title found". CLI docs are vague on what to actually pass for input
-i, --input <string> Set input file or device ("source")

I've also tried /dev/disk4 and /dev/rdisk4 none work. :(

Steps to reproduce the problem (If Applicable):

Code: Select all

$ HandBrakeCLI -i "/Volumes/FOO_DVD" -t=0 -v=9

Make sure Terminal can access external disks in System Preferences -> Security & Privacy -> Privacy -> Files and Folders.

That solved it thanks so much! I had tried sudo, but obviously that isn't the panacea it used to be for access.
I'm looking to automate the process of scanning and creating mp4 files. Would you recommend launchctl running on volume mount, or AppleScript Automation that runs my .sh script set to run "When you insert video DVD:"? And what, if anything, do I need to "Give access to external disks" to, so it will work?

I wouldn't use HB for ripping DVDs.
