There have been so many posts on this topic with not a one of them providing a solution to most peoples request. I've noticed in most of the posts that prople just give up on looking for a solution.
Anyway - a basic outline of the problem.
Opening a video - usually an xvid in virtualdub and going to file >information shows under compression: unknown (tag 0055)
Now of course this is an mp3 file and of course I have the appropriate acm mp3 codecs installed. I am unable to seperate the audio out as a wav file because of this.
Most people when offering advice usually seem to skip this statement (I have the appropriate codecs installed) and say - you need to install an mp3 codec - virtualdub does not support directshow codecs. - So please - I do have the appropriate codecs installed
I've gone through all the files I am having a problem with and checked the headers. Here is what I have noticed.
Every single file that has a problem has been encoded using nandub 1.0rc2 in combination with lame (between 3.90 and 3.96)
Files encoded using virtualdub or mod using the same lame codecs do not cause any problems.
Trying to seperate out the audio using nandub does not work either.
However, one anomally I have noticed is that files encoded using nandub 1.0rc2 build 1852 in their headers do not have any problems - so I am not sure if it is build 1853 or older than 1852 that is causing the problems as there is no build information in hte headers.
Files encoded using nandub1.0rc2 and a codec other than lame cause no problems.
Does anybody have any idea about what is going on here?
Please don't tell me to check my codecs - they are fine!!
Really appreciate any help on this.
PS: using virtualdub 1.6.10 on winxp.
see same problem in virtualdubmod |

You say you have an mp3 acm codec installed but you don't say what it is. Since you're so sure it's working I'm guessing it's one from Fraunhofer (you do know the lame codec can't decompress, right?). Can you check if it's the pro version? |

Sorry, but apparently they are not fine. 
Please ensure that you only have one codec installed for MP3. If you have installed multiple MP3 codecs, they will conflict and you can never be sure which codec is being invoked.
(FWIW, I'm a huge fan of the command-line LAME encoder, but I avoid LAME ACM like the plague. I've had nothing but problems with this codec.)

OK
Here are the mp3 codecs I have installed according to GSpot.
I have two instances of
fraunhofer IIS Mpeg layer-3 codec (professional)
I'm not sure why there would be two instances of this as I have not installed any codec packs - only mediaplayer 10 which I understand comes with this.
Lame mp3 codec v0.9.0 3.96 stable
FIL Original Filename lameACM.acm
But as previously mentioned - this only encodes - not decodes - so there shouldn't be any problem here right?
ffdshow audio decoder
but I have this disabled for mp3 - only used for ac3 and aac. Not compatible with virtualdub so not really relevent right?
MPEG Layer 3 Decoder.
FIL Original Filename L3CODECX.AX
Not sure what this is but digging further find that it is the Microsoft directshow codec for mp3.
for the two fraunhofer codes here is some extra information:
The first
ACM Format Name MPEG Layer-3
ACM Format Code 0x0055
ACM Driver File C:\WINDOWS\System32\l3codecp.acm

DSH DirectShow CLSID CLSID_ACMWrapper {6a08cf80-0e18-11cf-a24d-0020afd79767}
DSH Driver or Wrapper C:\WINDOWS\System32\quartz.dll
FIL File Description MPEG Layer-3 Audio Codec for MSACM

The second

Really appreciate any help you can give me on this.
PS: Have previously tried uninstalling ffdshow and Lame but didn't make any difference. |

That's the hacked radium codec, NOT the one that comes with WMP10. You could try re-installing WMP10 but I'm not sure how you'd go. |

Tried a WMP10 re-install. Didn't make any difference.
Tried deleting the fraunhofer codecs and then reinstall WMP10 - again - no solution to my problem.
I really am very convinced that there is some kind of issue with nandub. It can't just be a coincidence that every file that has a problem was made using nandub

Might not be the case this time, but the last time I looked into problems like this, the problem was that the Fraunhofer-IIS ACM codec wouldn't accept certain stream formats produced by the LAME ACM driver at around 80-112kbps. The LAME ACM driver cannot decode, so it is unable to assist in this issue. Apparently the Fraunhofer DirectShow filter is somewhat more lenient at validating the audio stream format, so Windows Media Player will play such videos. I wasn't able to determine at the time if there was a way to frob the format to work or to determine the required change.

Most files are around 128kbps |

Actually - on further checking, there could be somethign in this.
All files have been encoded with vbr.
Files that Virtualdub reports as having a data rate of 129kbps or higher there is no problem.
Any file with a data rate of 128kbps or lower will not work.
All files have been encoded using lame.
So - is what we are seeing here a problem between Lame and the fraunhofer acm codec not wanting to work with each other?
Any other mp3 codec I can replace the fraunhofer one with.
Directshow codec works fine.
Problem files I currently use tmpgenc (directshow mp3) in conjunction with ssrc to seperate out the audio - just takes a lot longer is all. |

actually strike that last post . . .
File encoed using nandub 1.0rc2 and lame 3.96
Variable bitrate.
Virtualdub reports data rate of 128kbps
Virtualdub reports Compression: unkown tag 0055
File encoded using virtualdubmod with lame 3.95
variable bitrate
Virtualdub reports data rate of 128kbps
Virtualdub reports Compression: Fraunhofer IIs Mpeg layer-3 codec
Things just keep coming back to nandub every time.

It's been a while since anybody has added a comment or possible solution.
I would really hate for this to go unresolved again.
As I said, there are many people who have posted with the same problem that I am experiencing and usually the topic becomes drawn out with any solution offered.
This must be a known problem by the developers??? |

I will only reiterate what I suggested earlier, that is to ensure that you only have one MP3 codec installed, and kill all the others.

I'm the one that asked the question. If I had a solution I wouldn't have asked the question now would I ? |
