No audio decompressor could be found using VirtualDub

[dapster]

I have a large WMV file generated using Windows Live Movie Maker - 97 Mbytes. I want to cut the file size down to be able to include it in one of my websites. I have used VirtualDub in the past but am having a problem with this WMV file. I get an error message - "No audio decompressor could be found to decompress the source audio format - Source format tag: 0162." I have loaded the VirtualDub plugin folder with the free codec package obtainable at videohelp.com/tools/virtualdub. This codec pack has enabled me to get VirtualDub to at least accept WMV files. I am using Windows 7 operating system.

Thanks in advance for any help!!

You need an ACM decoder for Windows Media Audio 9 Professional. I think you'll find it here:
https://www.videohelp.com/tools/WMV9_VCM

If not, you can try using the DirectShow plugin in VirtualDub.

Many thanks for your quick reply. Do I put the download in the VirutalDub plugins folder and then install it there?

[jagabo]

No, install WMV9VCM like any other program.

[dapster]

I did as you suggested but now have a different error message popping up - ASF files are not supported.

[jagabo]

Do you have the WMV plugin in VirtualDub's plugins folder? If that doesn't work try the DirectShow plugin.

[dapster]

I am not sure what DirectShow plugin I should download. There seems to be several types on the Internet. And, do I put it in the plugin folder?

Thanks

VirtualDub plugins go in VirtualDub's plugins folder (or Plugins32 or Plugins64). Use the link in this web sites VirtualDub page to get the source plugins. See the "Import Plugins" section.

Many thanks once again. Now can someone help me to install Lame ACM so that I may use it in VirtualDub? I have downloaded the Lame ACM codec and right-clicked on the .inf file and selected install. However, the Lame ACM codec does not show up in the list of codecs in the Audio section of VirtualDub.

Are you using 64 bit Windows? https://forum.videohelp.com/threads/271712-Lame-MP3-Encoder-on-Vista-x64#1723154

[dapster]

How would one find out?

[dapster]

I ran Belarc Advisor and found that my computer processor is 64-bit ready. And, I am using Windows 7 Premium (X64).

And, I am using Windows 7 Premium (X64).

Then you need to use the instructions in the link I gave earlier. And note that 32 bit programs require 32 filters; 64 bit programs require 64 bit filters. You can't use 32 bit LAME with 64 bit VirtualDub, or vice versa.

[dapster]

I am sorry I missed your earlier suggestion. I have since clicked on your link and downloaded the VirtualDub 64 bit version. Also, in the Import Plugin section, I downloaded the VirtualDub plugin pack. I put the 64plugins folder in the same folder where I have the new VirtualDub (64 bit) executable file. Then I ran VirtualDub and opened a WMV file. The screen opened up with a side by side display each containing the message "MISSING CODEC." I am stuck here!

Thanks in advance for any help

I highly recommend against using 64 bit VirtualDub. It is less stable than the 32 bit version, there are fewer filters available for it, and fewer source filters. Actually, I'd recommend against using 64 bit Windows for a video editing station. For pretty much the same reasons.

[dapster]

I have set up VirtualDub 32 bit on my computer and downloaded the Codec pack (32 bit). This has gotten me further along. I don't get the missing codec message on the inital loading of my WMV file. Now, I am stuck getting LAME to show up in my audio compression listings. I downloaded Lame ACM and followed the install directions. I right-clicked on the inf file and chose install. I don't know where to look on my hard drive in order to find the LAME codec but the install didn't give me any error messages. Sorry, to keep bothering you but I had used VirtualDub last year and had no problems with LAME.

You can't install 32 bit LAME on 64 bit Windows that way. You have to follow the instructions in the post I liked to earlier.

[dapster]

I tried!
1. Download the LAME x64 files (including .INF) here: http://members.optusnet.com.au/squid_80/lame64.zip
2. Open an instance of command prompt (Start --> Run --> cmd)
3. Change working directory to system32 (yes, system32) by typing "cd C:\windows\system32"
4. Type the following: rundll32.exe setupapi.dll,InstallHinfSection DefaultInstall 0 c:\Temp_Folder_Path\LameACM.inf

Make sure to replace c:\Temp_Folder_Path with the folder you actually have the extracted lame64.zip files in (for example, your desktop).

Got an error message:
An error occurred while copying file LameACM.acm. Cannot copy file to destination directory.

I have set up VirtualDub 32 bit on my computer

1. Download the LAME x64 files

The instructions are for installing 32 bit LAME for 32 bit programs under 64 bit Windows. You must use 32 bit LAME with 32 bit VirtualDub.

I'm aware of the nearly 2.5 year time jump here, but this seemed an appropriate place to ask, since you wrote what you wrote. (Personally, I'm opposed to continually proliferating new threads on the same or more-or-less same subject, when there may be reasonable places to update existing threads.) So, my questions:

64-bit Win-7 is now much more established in terms of how many users are running it. Has the intervening time period changed your answer on this ? I happen to be running W7U x64 on the box I've been using lately (I rotate amongst the use of a few different computers here), equipped with quite a few 64-bit video apps (where they are available) and a nice roster of 32-bit ones as well. That's one of the good things, in that you usually don't have to relinquish a good 32-bit program that you like: they just go in the Program Files x86 section, and you can continue to use them.

I happen to have Portable 64-bit VirtualDub on this box. (Curiously, neither the 32-bit or 64-bit portable edition of VDub seems to be included in the Tools section on VH. I don't even recall where I found them, at this point.) It is possible that my fondness for portable apps is a culprit here, or maybe it's just what you said about 64-bit VDub. (Never much of a problem noticed in my using the portable AVIDemux editions, for example.) I've found some 64-bit plugins, here

http://sourceforge.net/projects/portableapps/files/VirtualDub%20Portable%20Plugins/Add...f.exe/download


and elsewhere, and created the 64-bit plugins directory for them, as you are supposed to. The lack of usability continues though, albeit with changes along the way in the particular error boxes or messages. But they all seem to boil down to lack of some audio or video codec. Maybe I just haven't added in the right ones yet ? (The last one I added was 64-bit x264VFW, which I thought might be the answer, but it wasn't.)

I could see what happens with 32-bit VDub -- portable or regular -- on this box, or, if there is no working alternative, just run them on a box that has 32-bit Windows. That seems a bit extreme to me, though.

[jagabo]

64-bit Win-7 is now much more established in terms of how many users are running it. Has the intervening time period changed your answer on this ?

No. I still run the 32 bit version.

Curiously, neither the 32-bit or 64-bit portable edition of VDub seems to be included in the Tools section on VH

All versions of VirtualDub are portable. Just extract the files to a folder, run the EXE. Both 32 bit and 64 bit versions are linked to from the tools section.

Using 32bit WinXP SP3, the cursed dreaded "missing audio codec 0162" message in Virtual Dub is driving me MAD. Why people just not use standard mp3 format, I don't get it...

Anyway - I downloaded and installed the suggested WMV9VCM decoder, but after VD restart, the cursed message is there once again.
Could some FFD audio settings help?

Or do I must use the DirectShow input driver by default with this?!

[El Heggunte]

There is no ACM decompressor for WMA Pro.
The WMV9 VCM codec is for video only, not for audio =)
And if I am not wrong, ffdshow dropped support for the ACM interface "ages ago",
even before the 'tryouts' phase.
If I were you, I would use an intermediate Avisynth script.

Why people just not use standard mp3 format, I don't get it...

For the same reason why they still use the ASF container, Windows Movie Maker and the infamous Expression Encoder:
they are incurable noobs
