Hello all,
I am having a problem playing an .avi video file. I get the following message: "No audio decompressor could be found to decompress the source audio format. (source format tag: 0011)."
I am fairly new to using VirtualDub. What codec should I be using to decompress this audio format? I don't really even need the audio to play. I only care about the video.
Thanks |

Normally this should be the Microsoft IMA ADPCM CODEC = imaadp32.acm that you can find in C:\Windows\System32
If not, you can download this codec in zipped format:
> http://www.down-dll.com/index.php?file-dow...d=imaadp32.acm#
(If the download message does not show up after a few seconds, then click on the hyperlink at the bottom of that window.)
Unzip the "imaadp32.acm" to the C:\Windows\System32 folder. |

Abrazo,
I did already have that codec. And downloading it again did not fix my problem. I still get the same error message. The videos in question are from a security system DVR that had the audio disabled. Could that be causing this problem?
Thanks |

If you don't want the audio then you can just set the audio source to 'none' from the audio menu

Maybe that strange phenomenon in Windows Registry where ACM codecs get disabled (= status '0') ?
I was able to simulate and reproduce the warning of "No audio decompressor could be found ...".
Look into Windows Registry for this key, and verify that the digit (here indicated as 'bold') is set to '1' :
[HKEY_CURRENT_USER\Software\Microsoft\Multimedia\Audio Compression Manager\Priority v4.00]
"Priority1"="1, msacm.imaadpcm"
Be sure to quit and restart VirtualDub after changing from disabled to enabled (or vice versa if you want to test it out). |
