DVD2AVI: .D2V Problems in TMPGEnc

dcshoekid1 · #1 04-08-2004, 05:30 PM

Ok, I posted in KVCD questions, but then found this topic.

I have a .d2v, and tmpgenc doesn't read it. It says it is an invalid format or it's an unsupported file type. I have tried numerous versions. But the funny thing is, it worked earlier, but I needed to format. Now I re-installed the EXACT same version, but now suddenly, it doesn't want to work. Anyone got any advice on this topic or if not, does anyone have any sugggestions to whom I can/could contact?

Thanks.

What version of DVD2AVI did you use

Try 1.77.3

Actually, 1.77.3 is better, because it corrects many internal bugs and it's also faster.
I haven't used 1.76 now for about a year, and never experience any problems with 1.77.3

I'm sorry to be repetitive, but, which is better, 1.77.3 or 1.77 dg?

kwag · #6 04-09-2004, 01:06 PM

1.77.3

@kwag

Have you a link for this version?

THX, kwag.

Lol, I have version 1.77.3. Also, another thing has messed; it now recently stopped loadin vobs, and when I do, then press 'Ok', it freezes. But what I mainly need help on is the TMPGenc problem first. Thanks.

Which TMPGEnc version did you have?

Perhaps go to the envirolment settings of TMPGEnc and set the d2v file reader with a higher priority.

I'm sorry kwag but isn't neuron2 version 1.77.3dg?

If so isn't it on the same level as 1.77.3 that you pointed us on the link.
Bottom level: is 1.77.3 better than neuron2's 1.77.3dg?
If so can you explain us why?
TIA
Cheers

I have never tested 1.77.3dg

Because 1.77.3 has never failed on me, I never needed to try that version.
Now I ask: What does 1.77.3dg has to offer, that 1.77.3 doesn't

From the readme.html of decodefix100.zip

Introduction
The widely used tools DVD2AVI and MPEG2DEC suffer from serious problems, including frame loss. This can cause serious problems with audio sync and authoring with some tools. Not only that, but random frame access is not handled correctly and incorrect frames can be returned when navigating on the timeline via MPEG2DEC (and its clones).
There are three causes for the frame loss in the faulty versions.

DVD2AVI fails to flush out the final frame's digit to the D2V file before writing the 9 and closing. This causes one frame to to be lost at the end.

MPEG2DEC cuts two frames from the frame count as a workaround for 3 below. This is a kludgy hack that should not be necessary. Thus, thanks to this and 1 above, 3 frames will always be lost. They are lost at the end.

If the opening GOP has B frames before the first P frame (IBBPBBP...), then DVD2AVI generates an incorrect D2V file, in which the first digits for the orphaned B frames and some remaining digits are written out of place. Also, MPEG2DEC cannot decode the B frames prior to the first P frame, and so discards them. A number of frames will be lost equal to the number of B frames prior to the first P frame. They are lost at the beginning.
So, for example, if you edit a VOB and the resulting file has an IBBPBBP... opening GOP, you will lose a total of 5 frames, with 2 lost at the start and 3 lost at the end.

In addition to the lost frames, MPEG2DEC does not implement random frame access correctly. In fact it always throws away the first B frames in the GOP prior to the first P frame. If they are (say) frames 12 and 13 (in display order) and you try to seek to 12, MPEG2DEC will toss them and return frame 14 to you, without any warning or indication about it.

Finally, when 3 above applies the TFF/RFF flags in the D2V file are misaligned to the frames.

I have created fixed versions of DVD2AVI and MPEG2DEC3 that solve these problems. I modified MPEG2DEC to not truncate B frames prior to the first P frame and to not unconditionally reduce the frame count by two. I rewrote the decoding and random access code to work correctly with the D2V files generated by the fixed DVD2AVI.

For DVD2AVIdg, if your input stream starts with an open GOP, a message box will pop up warning you that the first few frames may not be decoded properly, but the frames will be retained. To avoid this problem, always cut your VOBs on cell boundaries. Do not make arbitrary VOB cuts with a binary splitter (such as VOBSplit).

Notes
Given a stream with an open first GOP, the correct frame count is returned and seeking works, but the orphaned B frames will be replaced with copies of the first decodable frame. That seemed the best thing to do. If the first GOP is closed, everything is perfect.
These fixes currently apply only when Save Project is used in DVD2AVIdg and then MPEG2DEC3dg.dll or DVD2AVIdg.vfp (VFAPI) is used for decoding. Future versions may add support for DVD2AVI's Preview and Save AVI features.

DVD2AVIdg and MPEG2DEC3dg are intended to be used as a pair. If you use faulty versions of either of them, incorrect and/or undefined behavior may result.

DVD2AVIg is baselined off DVD2AVI version 1.77.3. MPEG2DEC3dg is baselined off MPEG2DEC3 1.10.

No, I'm not

I just want to get to the bottom of it

I've seen so many releases available...
Imagine what newbies go through...
Maybe we can all agree on which to use/recommend.

@kwag

I've tested it again with the DVD2AVI Version 1.77.3 and the same results:
AviSynth 2.5x can't read the D2V File.
So I use again 1.76 without any problems.

jorel · #18 04-10-2004, 11:07 AM

one time i had problems with 1.77.3 too, don't remember details !

i'm using 1.77.3dg and (more)176 d2s modified .

dvd2avi FAQ draft from hakko504 have good explanations about each version:

Hya,
EM you could try 1.77.3dg and save the project as 1.76.
You'll find that option in the File menu.
BTW make sure you copy the Mpeg2Dec3dg.dll that comes with it to the Avisynth\plugins folder.
And be sure to delete/move all other Mpeg2Dec3.dll from that folder.
Keep only the one that comes with 1.77.3dg.
It worked for me...
Cheers

Encoder Master · #20 04-10-2004, 02:44 PM

Yes, but that's not the point.
As kwag said the version 1.77.3 works perfekt for him and not for me.
