  1. Hi,

    I'd like to extract the audio from several avi files in one batch, without converting them. I think I can do that with FFmpeg, but what would be the command line?

    Thank you.

    Code:
    for %%a in ("*.avi") do ffmpeg -i %%a -vn -c:a copy -y %%~na.ac3
    pause

  3. Thanks, I've changed ac3 to mp3 (that's the audio format for all of them) but it doesn't work in both cases, it says "no such file or directory".

  4. The names of the avi files must be without spaces ..

  6. I get this for certain files though: "Audio packet of size 21153 (starting with 0000000...) is invalid, writing it anyway."

    Do you know what that means?
