Thanks Gyan! You are a life saver! I really want you to know how grateful I am that you helped me with this problem. I had tried so many different ways to get this solved and got nowhere. I asked for help on the superuser group, but got none. I tried different converters but it seemed there was always a problem.
For example: I tried again to do this with VLC yesterday when I couldn't figure out how to do it with mp4box. I found the command to extract the video from the avi file rather quickly but could not get the audio extracted. I found examples for extracting audio from an avi file, but they never worked for me. There is a way to convert an avi file into an mp4 file in a single step, called a "Dump", using the GUI. After hours of trying to reproduce the results on the command line, I gave up. Of course, if I had looked at your original post again, I would have seen the command to get the audio using ffmpeg, but I had been reading the mp4box documentation and found the command to extract the raw video. I recognized it as the one you used in your first reply. I also saw commands for getting Audio but again, I could not get it to work. Well, maybe that wasn't for mp4box. :-) I have tried to many tools and read so much online documentation it is hard to recall what I found for what tool. :-) Anyway, I wanted to do this is as few steps as possible using a few tools as possible, which is why I didn't even think of using ffmpeg to get the audio and combine audio and video. But, the solution you provided will do. If my supervisor doesn't like it, he can try to figure out something else. :-) I think he will be very happy though. He tried to solve this for days, before he assigned the task to me. *Would you mind if I posted your solution on the super user group?* I just want other users of ffmpeg to have this solution available to them. It could save someone a lot of time and frustration. I will also include the bug report Carl Eugen Hoyos filed. *I will of course give you credit for finding the solution.* Again, thank you very much for your help! You have been awesome!!!
