how do I copy a DVD image to run transcoder on it later

how do I copy a DVD image to run transcoder on it later ?
will dd do it if so what would the command line be ?
what would the command line be for running transcoder to convert the mpeg2
to mpeg4 ?
will I have to mount the image on a loop device to run transcoder on it ?

Dunno if this'll help...

You could rip it to MP4 using Handbrake then use Transmagedon to change the format later if needed.
I've no experience of transcoder I'm afraid.

ok I copyed the scripts
the problem I have with them is what is the command lsdvd I don't have that command on slackware
edit found lsdvd installing it now
what do I feed them for $1

schneidz · 10-22-2014, 11:52 AM

install lsdvd (and any other dependencies). i dont use slackware but on fedora it would be yum install lsdvd.

the first parameter is the name of the dvd file.

Code:

#!/bin/bash
dev=/dev/sr0

 dvd=`lsdvd $dev | head -n 1 | awk '{print tolower($3)}' | sed s/_/-/g`
 lsdvd /dev/sr0 && ddrescue --no-split --verbose --block-size=2048 /dev/sr0 $dvd.iso

this update mite work better for you (on my pc it is /dev/sr0) but it is hard coded and wont work on iso backups no more.

this was just a quick-and-dirty script i made. sorry for bugs.

metaschima · 10-22-2014, 11:56 AM

I would use vobcopy to copy the VOBs off the DVD, then I would use ffmpeg to re-encode them.

Make sure to check the laws in your area for bypassing CSS encryption.

I think I ran a windows app that could rip to iso image under wine. Worked pretty well too. Slightly but not greatly slower than native rip in linux.
