VirtualDub 1.5.10 is giving me grief when I try to split some WAVs out of the .AVI files I have – note that this only happens on a very few files, and these always have – in File Information – an audio stream compression value of “Unknown (tag 0055)”. Trying to make a WAV out of these files always gives:- “Error initializing audio stream decompression: The requested conversion is not possible. Check to make sure you have the required codec.” Now, I’ve used both AVICODEC and GSPOT, both of which tell me the AVI files have a perfectly valid MPEG-1 Layer-3 audio encoding, and GSPOT even tells me that I have four valid codecs installed to read this…except VirtualDub doesn’t suss this. It’s 2 channel, not 5, so not that AC3 problem, and although I can use AVI2WAV to get a wave file, it is horribly unsynchronised with the video (presumably because the original is sampled at 48kHz and AVI2WAV keeps this, whilst VirtualDub lets one change it to 44.1KHz?) As I say, this only occurs on a very few .AVIs, but it’s really annoying that this is happening…why does VirtualDub not recognise the codec, when AVICODEC and GSPOT do? What can I do about it?
