Video file conversion seems to have audio codec problems

[joneall]

I am having multiple problems trying to convert an AVI for upload to Youtube.

When I run it with VLC, I get the message "THis AVIfile is broken." I have read numerous responses for this, but none of them seem to help.

So I assume it is readable and try to convert it to something Youtube will like. (Aside: Why the hell does a recent model of Canon -- A1000 IS -- not write files Youtube can read?) I have tried ffmpeg, winff and avidemux. They all fail for similar reasons (I think). Typical is the response of avidemux:

[BuildChain] Encoder initialization failed. Not activated.

It produces the following info:

I was trying to convert my AVI file to MPEG-4 ASP and MP3 as per

http://ask.metafilter.com/110012/Bes...tube-in-ubuntu

So what do I have to do to convert my poor broken AVI file?

Thanks in advance.

Also, I do not see why one should have to know about codecs, containers and more just to take a file and convert it for Youtube. I thought computers were supposed to make these things easy.

Re: Video file conversion seems to have codec problems

I tried it again with just "Copy" for the audio, instead of Lame(mp3), and it worked. But there is no audio in the output file.

So the problem is with the audio.
