Hi,
I'm new to VirtualDub & ffdshow.
Issue lies with audio codec support namely mp3, aac.
Configuration:
* OS: Win7 64bits
* VirtualDub 1.10.4, 32-bit (x86) version (following: "It is recommended that you use the 32-bit version unless you have a specific need for 64-bit execution")
* ffdshow
First, with mp3.
Althought, I re-encoded (with ffmpeg) my test avi with mp3 CBR, Vdub claims it's VBR (Mediainfo confirms it's 128 kbs CBR joint stereo 44.1Hz)
When I click PLAY the avi with mp3 audio I get "Error initializing audio stream output size".
Second, with aac
Similiarly, when I PLAY the avi with aac audio codec I get "No audio decompressor could be found to decompress audio format (source format tag: 00ff)".
Remark:
In ffdshow audio decoder configuration, whether or not I "libavcodec" activate or de-activate mp3 or aac audio codec support, makes no difference.
Thanks for helping.
P.S. I also tried both version of ffdshow, namely
32-bit: ffdshow 1.3.4500 from http://ffdshow-tryout.sourceforge.net/download.php
ffdshow_rev4531_20140628 from http://sourceforge.net/projects/ffdshow-tryout/ |

Virtualdub doesn't use DirectShow codecs, it uses VFW codecs for video and acm codecs for audio
FFDShow has (32bit) a VFW configuration page, but doesn't supply ACM codecs for audio - so it's not a complete package for virtualdub
There are links in my sig for the ACM codecs you want
Alternately, virtualdub can also use plugins that handle ass of the video/audio themselves
eg
FFDShow plugin uses ffmpeg's dlls to handle all of the decoding, no codecs needed
DirectShow plugin uses DirectShow codecs
These two have the slight drawback of disabling direct-stream-copy mode as they've already decoded the file before it gets to virtualdub
