    Tidbits for transcoding video files and converting audio files (to AVI and MP3)

    I would just like to suggest a couple of tidbits for whoever might need them.
    I am using Hardy Heron (KDE 3.5).
    I needed to convert windows audio files (f.int. wma) to MP3.
    Audacity cannot read wma.
    So having used most of this day to prowl around the Internet, I found that the simplest possible solution was just sitting there in the repos (with Adept!) as a KDE GUI no less:
    Install lame with Adept
    Install soundkonverter with Adept
    And there you go, a nice little graphical application you can pick from the menu. Should cope with most common codecs.

    I also needed to transcode a podcasted M4V-file to AVI, so that I could play it on my non-iPod multimedia/MP3 player.

    Most video transcoders are DVD rippers, it seems, and I was unable to make them accept single files from my hard disk.
    Transcode is apparently a powerful tool, but learning to use it appears to be quite a large cup of tea. Mencoder uses transcode, but is also quite an enormous cup of tea - you have to know the ins and outs of audio/video containers, which I don't.

    But I found this nice command line to use in Konsole:
    mencoder <input_movie> -oac mp3lame -ovc lavc -o <output_movie>.avi
    which works like a piece of cake, assuming you have installed mencoder and its dependencies (using Adept). Don't ask me what -oac mp3lame -ovc lavc -o means, but it outputs exactly the file I give it, as an avi-file, a wee bit larger than the original file, but that is because AVI generally takes just that much more space.

    And, oh yes, I almost forgot: You will need to have the codecs from medibuntu installed.
    In general I found this guide very helpful:

    Just an educated guess, (possibly wrong): "oac" = "output audio codec", "ovc" = "output video codec".
