Tryint got make a "virtual DVD" of sorts

Postby SQ » Wed Sep 06, 2006 6:43 pm

Okay, so on this other forum I'm on, this guy is asking this:
Lintor wrote:Allright, I need a dvd ripper, that can take a dvd from my collection, and rip it into a file, a file that can support h264/x264 video, and contain multiple dub/subtitle streams.
I was told that the file format I'd need would be a mp4 file with h264 encoding or something like that.
Money is not an issue and this will be kept on the legal side of the law.

EDIT: I guess I need a ripper and encoder, most I thought did both, and seem to, but I found a few programs that really just rip it to remove the copy protection.


So if I'm taking this the right way, he basically wants the functions of a DVD(multiple audio and sub streams) in a single video file somehow.

Now, I honestly don't think this is possible. BUT, it was an interesting question that no one on the other foum has figured out the answer to.

So, I was wondering if it were possible(even if you have to have a folder of certain files for the streams), how could you do it?

The MP4, Matroska, and (going all the way back) Quicktime containers have supported multiple video, audio, and subtitle streams for a long time, and make it trivial to work with multiple streams. AVI supports it too, but it's not nearly as nice (nor often as used).

The way I'd go about doing it is transcoding each track to something appropriate (perhaps H.264 for video, AAC for audio, MPEG-4 streaming text or SRT subtitles for subtitles) and then muxing them all together into a single MP4 with e.g. mp4box. The Matroska process is similar, except you'd probably use mkvmerge to do the final muxing.

It's not too hard, actually. Just an extension of what you'd normally do for a single audio and video track.

Are there any guides on how to do this process?

There are some guides at http://www.doom9.org/guides.htm, though I would supplement those by reading http://gpac.sourceforge.net/doc_mp4box.php.
