Some additional information: the `-ab' and `-b' options seems to be broken on my machine, since they accepts any argument, even those which will cause error in the case of Ubuntu, for example `@@' or so. Nevertheless, the option parsing is not completely broken, because an unknown option ffmpeg

But VBR seems to be disabled with the command line I used... And, whether VBR is enabled, the wrong parsing of the argument of bitrate options indicate that some error must exist somewhere. On Tue, Sep 06, 2011 at 10:42:06AM -0400, Michael Mol wrote: 'lame' is an MP3 encoder. VBR is 'variable

OK, but I was actually converting an FLV file, and didn't want to use both programs, especially when ffmpeg already has support for libmp3lame. Anyway, there must be some problem in ffmpeg/libav (probably) or something else (less probable than the former) on my computer. On Tue, Sep 06, 2011 at
