Got VOBs, want DVD! :)

[Wizeman]

OK, suppose I have a handful of VOBs that my machine plays... just that they happen to be very non-standard... which means if I were to demux them, I can't import them into DVDSP...

So how do I make a DVD out of the VOBs? My player can play them just fine (tested a small clip and authored as DVD on a CD-R), but when trying to make one huuuuuuge MPEG2 and author it as DVD, I keep getting thwarted by out-of-memory-like errors... Even when demuxing a MPEG2 of 1.56GB (a SVCD title that I have extracted and joined together) I can't keep header info, which means I can't even remux them...

So does *anyone* have any ideas? Seems such a shame that my player can play DVD-SVCDs and there seems to be no way of *creating* them hehe...

Please help, I'm going insane here.

Things to try:
1) run folder of vobs thru MMT's vcdxgen and vcdxbuild tabs set for dvd.
2) demux, re-mux in MMT's mplex as dvd, vcdxgen, vcdxbuild...

[Wizeman]

OK; weird results...

First tried to get MMT to like my MPEGs, but it only gave me "segmentation fault" and a ton of other errors. Only managed to get it to make a proper VIDEO_TS if I first demuxed and remuxed the files as DVD - the result was a disc that looked fine in the player - but no sound... guess this method demands ac3, whereas the "quickfix" didn't...

Anybody got more ideas? I'm getting desperate

[Wizeman]

It works

Thanks Ross for the tip - but it seems I *do* have to demux-remux each file individually... a *LOT* less taxing than transcoding the audio to 48khz (letalone the video hehe) but still irksome... wonder if there's a way to "fix" the MPEG2 stream so I don't get a Segmentation fault when trying to make the VIDEO_TS folder using MMT... anyone?

[Ross]

A segmentation fault usually indicataces wrong mux type.
That's why it took it after re-muxing as dvd.

What audio format did mplex report when muxing?
Or maybe MPEGInfo will id the audio type.
If it's mp2 at 44.1khz, you may need to re-sample to 48.0 khz.

[Ross]

Yes, I could probably re-write a part of the code to have MMT work with the original vobs, I'll take a look at that.

[Wizeman]

Thanks for a great program :P

Seems that those MPEG2's still do need to be remuxed (as DVD) in order for MMT to get ifogen cracking... pity, takes a couple of extra steps How does ifogen determine a segmentation fault? Seems weird (well, to me who knows precious little about the workings of these things) that it should be OK muxed one way and not the other.

What *really* threw me for a loop was that even Apple's own DVD Player could play this xDVD - even when one chapter was NTSC and another PAL LOL! Granted, the PAL didn't look too good when I did that (green blocks on the upper half of the screen) but my stand-alone had no complaints

On a semi-related topic - my DVD player is supposed to be able to play MPEG-1/2 streams "straight from the DVD", but I'm guessing I'll have to put it in some form of wrapper? Can I stick the mpgs as avseqxx.mpg and manually fix a SVCD structure? What would I have to do to get the player to play those avseq's consecutively?

Thanks again,
