What to do when even VDub frameserving won't work?

[DRP]

I've got this XviD video which won't load in TMPGEnc. Not a problem I think to myself, this has happened many times before. I'll just frameserve it through VirtualDub and that'll fix it... it always has in the past.

Not this time! The signpost file gets rejected by TMPGEnc as well.

What do I try now please?

Are you using Virtualdub MOD? Could the vid have vbr audio? I understand Vdub mod handles that. :c)

No. I'm using the bog standard v1.5.4 of VirtualDub.

The video does not have VBR audio. The only thing slightly unusual about it is that the audio is completely uncompressed - ie. PCM @ 44.1, 16 bit, 2-channel stereo.

The only other thing I've noticed is that VirtualDub identifies the decoding codec required to be XviD whilst AVIcodec says it was encoded with a DivX 5 variant.

Hmmm. I don't know what it could be then. Sorry. But someone will know. :c)

I use Gpot to check the few avi files I've worked with and it shows whether you have the necessary codecs. I've never used "AVIcodec" before.

I know there was a recent new Divx5. - 5.1. Perhaps that will handle the variant?

Thanks for trying to help. You might wanna take a look at AVIcodec if you have time. I started off with GSpot too, but found AVIcodec to be superior, so I changed over.

I have Dr. DivX 1.0.2p & DivX 5.1 already, so that isn't the problem either.

I have had much success with the VDub frameserver in the past and nothing serious has changed with the config of my computer recently.

Sorry I was useless :c*

Thanks, I am going to download AVIcodec right now. You can never have too many tools, right? :c)

Well for me it was a case of being so sure that AVIcodec was so much better than GSpot that I didn't even bother keeping GSpot at all. I was never going to use it again once I had found AVIcodec, so I didn't keep it. One replaced the other - no "extra" tool.

I can't help much, but you could try frameserving with AVIsynth. Even though it has a steep learning curve, I would not think it would be hard just to do a straight-forward frameserve. Or you could try some of the other frameservers in the tools section.

There are few things you can do to try to solve the problem.
1. reinstall the handler on vdub
2. change the audio to wav audio
3. use the fourcc changer availble in the tools section to change the avi
from divx5 to xvid.
4. make sure the direct show reader in the environmental settings of
TMPG is set at 1 or 2.
To Gees, the avicodec can also handle mpg1 and mpg2 files. It will give you their characteristics such as frame rate, resolution, audio and video bit rates, etc.

Thanks LaddyDaddy. :c) And DRP for mentioning it in the first place. Don't know how I overlooked it all this time! :cD I've only ever come across Gspot mentions in the past.

Now a part of my arsenal. ;c)

I just told someone else this but I'll do it again.
Open file in Vdub, set full processing mode for audio and video
start frameserver.

Open the signpost file with another instance of vdub and get
the video info. it should be PCM and uncompressed video.
If so , how can TMPGenc complain about that ?

Thanks for the suggestion, but no thanks. I've tried AVIsynth before and it's a little bit more complicated than I really wanna get.

I've tried all these things and no go. I've installed the new v1.5.5 of VirtualDub as well but it made no difference. When I play the file (which the computer does just fine), WMP reports DivX being used as the decode filter. The fourCC code is also set at DV50. It seems that VDub is incorrectly identifying the file as XviD for some reason.

The DirectShow filter is already set at #1 priority.

I've done this and yes the second VDub does report both uncompressed video & audio but TMPGEnc still won't accept it as input.

I've noticed a couple of new things myself. When opening the file in VDub I get "Error decompressing video frame 0: An unknown error occured (may be corrupt data). (error code -100)". VDub cannot play the file at all.

I ran it through VDub-Mp3 Freeze as well and every single one of the 5162 frames is reported as being corrupt, yet the file plays perfectly in WMP.

Someone with fewer brains than me has obviously mucked around with this file at some time to solve an audio sync problem because the framerate is 25.003fps.

Any further help or suggestions anyone can offer would be greatly appreciated.

[Laddydaddy]

hmmmm...
This is a long shot. Vdub complains about frame zero. Start frameserving from, let's say, frame 10. If the first or first few frames are problematic maybe you can skip them. See if TMPG will accept the file if you start frameserving from something other than frame zero.

[FOO]

VDub cannot play the file at all.

Red Herring.

We have all been working on a frameserving problem all this time
and NOW we find out Vdub can't read the file to start with.

"We don't need to worry about those pesky error messages, they just put those in there to piss us off. Let's ignore them and continue anyway"

Have you noticed ?
Most of the posts on this forum about impossible problems originate
from downloaded Xvid or Divx.

Why don't you guys get wise ?

[xtreemkareem]

If it's XVID, would changing the Four-CC do anything, or am i just pretending to know more than i actually do?

Are you actually trying to help at all or are you just editorialising for the hell of it? Can I assume you have nothing constructive to offer?

[FOO]

Sorry no, I have nothing constructive to offer.
I decided yesterday to boycott all Xvid problems.
I don't have any to experiment with, so I can't learn anything.

You have to admit I tried.

Good luck with your problem
