Hi,

I'm starting to run low on space on my HD and would like to change some of the ISO files I have to xvid. Ideally I'd like to do this from the command line, so I can write a shell script to do a few at a time.

I have searched around and can't seem to find a command line use of transcode that would do this.

Is there a way to do this?

Cheers

Victor

Do you mean NUV files? ISO files are images of DVD (or CD'S), you cannot directly convert them to XVID.

NUV files are not a problem. The files I am referring to are DVDs that I have ripped to ISO, and now would like to have a lower size.

I could go through the process of putting the DVDs back into the mythtv box and ripping them again to a lower quality, but that is a bunch of manual intervention I was trying to avoid.

What I notice is that the MTD ripps from the DVD first to a temporary dir/file then does the first and second pass. What would be a solution would extract the ISO to a temproary file, then run the transcode against that (or the ISO directly) instead of a DVD.

I have a dozen or more DVDs that I have put into storage because I had ripped them to the HD, but with space getting short, I thought I would just transcode the image to a lower quality.

Well, I'm moving forward I think:

I just remembered that I can mount the ISO file as a temporary directory:

Code:
mount -o loop -t iso9660 file.iso /mnt/test


Once that is done, is there a way to run the MTD against the mounted ISO, and use the default settings?

Looks like this article may help with converting VOB files to XVID:

jammad,


Thanks for pointing me to that script! While not exactly what I was hoping for, it will definitely automate a lot of the process :D
