Ubuntu 8.04: BD Decrypt fails when not root
Posted: Fri Jul 30, 2010 5:18 pm
Hi,
I just downloaded the linux version of makemkv. I'm having a problem on Ubuntu 8.04 where I cannot "open" the BD drive when running as myself. When running with sudo, it works fine. From the log:
When it was running, I checked lsof and it appeared to have just /dev/scd0 open (not /dev/sg*). I do have read/write perms on that device (a Samsung BD drive):
Any idea what the problem could be? I prefer not to run things as root.
Again, it seems to open the disc and list the titles as root. I'm extracting an mkv right now..
Speaking of that, the extraction seemed fairly slow at first, and I was worried it was going to fail. It seems to speed up and slow down a lot. I'm extracting the feature on Toy Story 2, and it seems like it varies between 0.1x (50Kb/s) and 3.6x (15.6MB/s). Is that just seeking between different files that make up the movie? (like the various subtitle and audio tracks?).
Thanks,
Drew
