ACM failed to suggest a compatible PCM format

[Jim Ford]

I'm getting the above error with Avisynth, and have no idea what it means or how to fix it (I've checked the docs with no luck)!

(All I want to do is put a few sample clips of videos onto a PC and I'm finding I'm up to my ears in weird apps like AutoGk, AViSynth, Vitualdub, Megui, Yamb, dgmpgdec, Besweet, Belite, etc., etc. - and more different file types and acronyms than you can shake a stick at! Why is video so complicated? :mad: )

Video is a pretty complex topic. That's why AutoGK, MeGUI One-click, and Recode exist, so you don't have to deal with any of the mess if you don't want to learn about it. And unfortunately the seven major file types, and the different encoders available, are just part of the domain, because each suits a different audience. That's what happens when companies each invent their own formats.

I _did_ try searching - using the link on the home page (google search www.doom9.org), with no hits.
Now I've tried using the link on this page, I've come up with several hits which I'll digest.

Look at the top of the page. In the menu bar, there is a "Search" function, which allows you to search within the forum.

Actually (& unfortunately) the one on the menu bar searches the entire forum, not just the current one.

Are you using Nero WavEditor to edit your audio?, - because WaveEditor 3 (Nero 7) creates a WAV file header that may cause that error.

Hmm, could have been - or maybe Virtualdub. I've been thrashing around with various apps. - perhaps I'll remember when my brain stops hurting!

Thanks for the suggestions.

What kind of audio is it, Mp3, AC3, ...? If its mp3, you'll have to demux with VDubMod and import with MpaSource. There is a post on the VDub site about this (0055 unknown tag) and I think Avisynth's avisource() uses that portion of VDub code.

If its AC3, install AC3ACM (http://fcchandler.home.comcast.net/AC3ACM/AC3ACM.zip) and that will take care of it.

I found this (http://forums.virtualdub.org/index.php?act=ST&f=3&t=10931&hl=unknown tag 0055&st=15) on the VDub forum(look for Squid 80's post). If the link is broken, search for "0055 The Problem That Wont Go Away", its on page 2.

Essentially it says, edit the avi file with Vdub's Hex Editor:

"In the hex editor search for "auds", then a little bit further on there should be "strf". Scroll the cursor through the following bytes until the hint at the bottom of the hex editor window says you're at the wBitsPerSample field. (Make sure Enable AVI field assist is turned on under the edit menu.)"

then, changed it to 00.

I have not tried this since i don't currently have a file with this problem but, I would certainly like to here some feedback if it works.

I came across this problem as well and DirectShowSource works for me. (In my case it's a VBR mpeg codec that's incorrectly identified).
But I wanted to save the wav intact (non-decoded) and I can't do that with Vdub or avisynth. Vdub loses some audio at the end and with avisynth script I get PCM of course when using DirectShow.
So in case someone else has a similar problem try Nandub. It worked without loss in audio length and preserving of course the encoding. (no script)

EDIT:Spelling mistake

Came up in the dev forum as well (I bet this is the thread squid_80 referenced too):
