  1. Assume I have a couple of *.mp4 videos with the same resolution: aaa.mp4, bbb.mp4, ccc.mp4

    I want to append them with ffmpeg without re-encoding

    How can I do this?

  2. Ok, thank.

    However ffmpeg seems to have difficulties to recognize the filelist properly.
    I wrote into file.txt (on win8):

    file "D:\\videos\\toconcat\\1 aaa.mp4"
    file "D:\\videos\\toconcat\\2 bbb.mp4"
    file "D:\\videos\\toconcat\\3 ccc.mp4"

    Then ffmpeg tells me:

    [concat @ 00000000004ca9a0] Impossible to open '"D:\\videos\\toconcat\\1'
    D:\video\ffmpeg\file.txt: Invalid argument

    I saved the file list as UTF-8 encoded

    Whats wrong?

  3. Use single quotes, not double quotes.

  4. It works. Thank you.

    und just one more question:

    Assume I want to put a comment line into file list: How do I mark it?

    With a semicolon at the first column?
