    Convert MP4 file to avi

    I used my camera to make at video. The video is in the MP4 format. I would like to convert this file to an avi file. What command would you suggest to make the avi file using ffmpeg and lame?
    (I know how to do this with mencoder but I would prefer to have more control with ffmpeg and lame).

    The details of the file that I would like to convert are:
    ffmpeg -i M4H00846.MP4

    Re: (SOLVED) Convert MP4 file to avi

    This worked for me :

    1. Install ffmpeg
    sudo apt-get install ffmpeg
    2. Convert your video
    ffmpeg -i myvideo.mp4 -vcodec mpeg4 -acodec ac3 -ar 48000 -ab 192k myvideo.avi

    Good luck
