VirtualDubMod 1.4.13 Mpeg2 issue

[Blackout]

hi,

as far as i can see, the big bonus of using the "Mod" version of Virtualdub is that it will load in Mpegs directly...not just AVIs.

However whenever i try and load a mpeg2 that was created by my MAtrox PCVCR (they are 704x576 Pal mpegs) i get an error from VirtualDubMod in Windoews XP "Incomplete Mpeg File Detected...Last frame is maybe corrupted"....then a second popup window... "mpeg does not contain video stream". :(

The mpegs load up fine in DVD2AVI, Windows Media Player, etc, and there is definately vision.

Any ideas what the problem is?

Many Thanks,
Blackout

This error comes the MPEG-1 handler, not MPEG-2.


MPEG2 files must have a vob extension (just rename them) to be opened with VirtualDubMod. I currently have not enough knowledge in mpeg specs to tell if a stream is mpeg1 or mpeg2.


Also, please read bug reports and support requests before posting. This issue has been raised a number of times.

Hi Pulco,

thanks for the response, i did go to the VirtualDubMod webpage and went thru the forum and FAQ, couldnt find anything on it. So i did try ok!! Thanks for the info. It works.

Just to support other ppls requests...it would be great if VirtualDubMod would load the mpeg2 audio stream from the file directly.

Thanks again,

Try fccHandler's modified VirtualDub with MPEG2 support (link below), maybe this one is able to load that file since in does not only support VOBs but also regular MPEG-2 program streams (tested).

In case that card creates a MPEG2 transport stream, you could try to convert it to program stream before trying to open it. There are some tools for this elewhere. Or try to demultiplex them with TMPGEnc and load the elementary streams...

It's not in the FAQ indeed :)

However most bug reports in sourceforge concerning MPEG2 mention this problem.

You're absolutly right about audio. Maybe with fccHandler's mod we'll be able to do it in vdubmod.

I don't know too much about either tool, but I believe that VdubMod is not an actual MPEG-2 parser, but rather has some sort of DVD2AVI wrapper implemented (maybe why it can't do the audio?) and that other tool (Fcchandler's mod), as far as I know, is a true MPEG-2 parser, and can directly decode and re-encode any MPEG-2 video and AC3 audio.


...correct me if I'm wrong
