Re: [PLUG] Video question

["Louis Kratz" <louis.kratz@gmail.com>]

The vob files on a dvd may contain other information than the mpg data stream.  This includes alternative audio tracks, subtitles (which are stored as bitmaps), menus (mpgs plus a menu map file), and alternate angle video streams.

Renaming the vobs typically works because most video playing software can parse the data stream.

Eric, if you have that store convert your video for you, the dvd will most likely be what Brent said, NTSC dvd.  If they don't encode encryption onto the dvd, you can easily copy the vobs to your hard drive, then pull out the mpg stream you want via mplayer, mencoder, ffmpeg, and lots of other nifty linux pieces of software.  If they do encode the protection, well, I am not going to get into that as its a hot topic among fair use advocates and such (I doubt the store will encode the CSS encryption).

The easy, no frills way if you get a dvd without encription:
mplayer -dumpstream -dumpfile out.mpeg dvd://
That will play the first title on the dvd and dump the mpeg-2 stream to a file out.mpeg.

Hope this helps!  If you are really into home movies though, I would recommend getting a capture card.  I use the hauppauge 150 MCE, it encodes to mpeg-2 on the card.  Using the ivtv linux driver, I can plug in a vcr, old camera, or tv line and just cat /dev/video0 > 
out.mpeg to dump the stream.  Works like a dream!  But thats an investment you may not need.

The files on the DVD are in VOB format and can be converted to other formats with software packages available online.  I have also read that VOB files are in mpeg-2 format and they can simply be renamed from *.vob to *.mpeg and will play that way, but I have never tried it.   Maybe someone on the list has tried this??

I thought DVDs were just a collection of mpeg files with some other files for the menus and stuff.  Maybe you could just copy the mpeg files from the dvd??

If you live near Bensalem there is a New York Camera on street road, and in south philly there is Calumet Photographic both offer professional services and will be much more knowledgeable than the local drug or video store. Of course professional means $$$, but a phone call can't hurt.

Good places to go and try out high end gear, and then go and buy it online.

Good Luck, & Best Wishes for you and yours

This is only tangentially related to Linux but I need some advice/help.

My daughter has to complete a 3 minute speech on my old VHS-C video tape
recorder tomorrow, have it converted to one of these formats:
[wmv|avi|mov|mpg|mpeg|mp4|3gp] and upload it to the contest site on Friday. A
college scholarship or considerable portion thereof could be in the balance here.

Neither of my computers has the capability to take a video input (skip long
"Pinnacle sux" story here). The Camera Shop will convert it for $29.99 (3
minutes or 2 hours - same price) but they have no freakin' idea what the file
format is. They just say: "You put the DVD in your DVD player and it plays!"

Does anyone have suggestions about going from VHS-C to a file in short order?
Perhaps someone could help out - I'd be happy to pay the $29.99 and drive over
if that helps :-)

Thanks!

Eric
