AVISynth, MPEG2DEC.DLL and Working

Blight · 21st November 2001, 23:37

Ok, I've got AVISynth 1.05 installed, working fine.

I took the latest MPEG2DEC.DLL file I could find (dated 08/16/01).

I wrote the following 2 lines into the script:
LoadPlugin("d:\t\MPEG2DEC.dll")
MPEG2Source("d:\t\clip33.vob")

When I try to open this script in any program, I get an error message:

Avisynth open failure:
MPEG2Source: couldn't open file
(d:\t\vcd.avs, line 2)

Now, the file exists there. I tried several other files, including video-captured MPEG2 files, VCD MPEG1 files, VOB file off a DVD and a VOB file off the Hollywood+ Star Trek 8 sampler CD.

All give the same message! Am I missing anything? Is there anything else I need to do for this to work?

mpeg2source is to load d2v afaik (at least it works with those just fine..)

Yeah, I wasn't aware that you needed to use DVD2AVI.

The thing is, why couldn't DVD2AVI decode the audio to WAV rather than demux to MPA, it adds yet another step

dvd2avi decodes the audio to .wav! Check your audio settings please.

I did check, even though it was set on "decode", I was left with an MPA file.

This was from an MPEG2 Video-Capture source, so it wasn't AC3 Audio. Probably MPEG2 audio of some sort.

Hi Blight !

Truman was wrong. DVD2AVI only decodes AC3 streams to wave.
You can use Winamp to convert your MPA (stands for MPEG Audio) to a Wave file. I currently thinking about implementing a MPA to Audio function into AVSGen by using the XAudio Lib.

I have avisynth1.05 and the latest version of mpeg2dec as well. i generate the dvd2avi file and then load it, and avisynth throws an 'unrecognized exception' and doesnt load my video into nandub. anyone else experience this? any insights are appreciated

Try remaking your d2v file, and make sure you are using the correct DVD2AVI (use the one in the GordianKnot package)

This damn problem is UNresolved yet, it also happens with Avisynth 2.04, strangely only with some PC configurations, many dudes many times have reported this issue.

Time ago it happened also with my PC/config...
now it works...

Don't now specifically what may solve or hang avisynth by that "unrecognized exception" (that points to nothing, because the script setup, the d2v file and the vobs/m2vs are *perfect*)
The BAD point is that sometimes happens even after *fresh* Windows install!!

?????????

(hope avs developers could know anything about this

)

Are you using a later version of dvd2avi than 1.76??

No no no, sadly the problem goes over simply mistakes, I have tried remaking script and data files (avs, d2v...), use lower case names, simpler directories, clean and restore avisynth entries in RegEdit and some various incredible things (like using notepad to edit script files... not UltraEdit!!!)...

- DVD2AVI 1.76, 1.74, 1.77.1 (1.77.3 not compatible)
- MPEG2DLL.DLL, MPEG2DEC2.DLL
- Avisynth 1.0b5, 1.0b6, 2.03, 2.04

Trust me, I have experienced this many times in other machines (with my PC 1 time), I know perfectly how works setup with AV tools...
it's very frustrating.

When it happens, *SEEMS* THERE IS NOTHING TO DO TO AVOID IT !!!!!

It could happens under Windows XP (Pro/Home) or Windows 98SE, don't sure about WinME.

I had a similar problem after upgrading to XP Home & Win 2k Pro... No matter what version DVD2AVI I used, I would get that 'unrecognized exception' error. Eventually, I replaced mpeg2dec.dll, re-created my .d2v project, and I was back in business!
I dont know why replacing mpeg2dec.dll fixed the problem, maybe it had become corrupt after upgrading Windows?... Anyway, I'd delete all the .dll's you are currently using, download them (possibly from another source), and try again.
