I’ve been messing around trying to make a live-CD with some transcoding/ripping utilities built in to utilize some of the spare hardware I’ve got lying around. More on this later, but I’ve been reworking the guide @ http://willhaley.com/blog/create-a-custom-debian-live-environment/ with my own utilities and tools.
One problem I’ve been challenged with over the last couple of days is HandBrake-Cli bombing out with the message:
[email protected]:/mnt/Videos/Movies/dvdrip/91# HandBrakeCLI -i BHD.iso -o BHD.mkv –preset=”High Profile”

libdvdnav: Using dvdnav version 4.1.3
libdvdread: Missing symbols in libdvdcss.so.2, this shouldn’t happen !
libdvdread: Using libdvdcss version for DVD access
This has been bugging me, as it worked before I converted the image to a livecd. I wondered if it was some kind of problem with the lack of ‘real’ disk space, or a lack of memory or something like that, but nothing I could find would identify it.
Finally, I started looking into libdvdcss rather than HandBrake itself. I think what confused me is the symbols error looks like a warning, especially given that there is a follow-on message which looks like libdvdcss is continuing. Anyway, eventually! I ran an md5sum on the libdvdcss.so.2 file to see if it matched a non-live machine (to a virtually identical build).
[email protected]:/# md5sum /usr/lib/x86_64-linux-gnu/libdvdcss.so.2
N.b. libdvdcss.so.2 is symlinked to libdvdcss.so.2.1.0 in my current Debian sid based build.
On the donor machine

Hope this helps someone, and I’ll be back soon with more details about building a live image, then booting it using iPXE.
