Hiya!

I'm trying to backup a DVD9 to a DVD5. As far as audio and video is concerned this is actually no big deal. But although I tried and searched the web for hours I'm unable to find an (easy) way to transfer the subtitle streams into the backup copy!

I ripped the source DVD with dvd::rip, and then extraced the subtitle streams (at least thats my assumption...) like this:

tcextract -i orig.vob -t vob -x ps1 -a 0x23 > backup.sub

And I thought I could simply multiplex it back into in the shrunk video stream. But I couldn't find any way to do that! Mplex does only audio and video multiplexing. Spumux does subtitle mplexing but needs a special input file and can't handle already existing streams. If I could easily generate that input file from the subtitle stream and use it as input, that would be great as well. But the only way I can see is that I'd have to generate that file manually for each and every subtitle picture, or retrieve the text with a subtitleripper and some crappy gocr + hand editing(but, hey, that's ridiculous!). But that can't be it?! Is there really no other way?? I actually don't want to spend days for backing up a single DVD! The more so as I have a ready-to-use subtitle stream!

Any help would be greatly appreciated!

I haven't used it much, but 'spumux' (part of dvdauthor) can mux in subtitle streams.

If you haven't already, check out dvrequant (by our own Steel_J) for ripping DVD9 to DVD5. It's still under development, but can help ripping large titles and getting them straight to a ready-to-burn ISO image. I don't think it does subtitles yet, but it's getting there!

Well yes, it does subtitle mplexing, but as far as I found out it only works with a manually written input file (correct me if this is wrong). And there is no (at least no obvious) way to let that file be autogenerated from an existing subtitle stream. Well, perhaps it would work to write a lengthy script which uses some existing subtitle tools to extract the individual subpicture images and the timecodes and in the end writes such a file, but, hmm, I was hoping for an existing solution

Well, yes this suggests the gocr way. But last time I did that the recognition was pretty bad and it was quite some work to get a correct subtitle file. Is there really no way to mplex in the existing, ready to use, subtitle stream??

Actually. if you run spuunmux on a VOB you will get a bunch of png-images and a sub.xml file for use with spumux.

Yea, cool! This is kind of what I've been looking for! It seems to have some issues though, but basically it seems to work that way. Thanks a lot!
