Hi all:
    I download ffmpeg form CVS 2005-5-20 and build it on msys1.0.10(include mingw3.2.0) by these steps:

    cd c:/projects/lame-3.69.1
    configure --prefix=c:/mingw --disable-shared --disable-decoder
    make install

    cd c:/projects/ffmpeg
    configure --enable-mingw32 --enable-memalign-hack --enable-mp3lame
    make install

    when i try this:
    ffmpeg -i E:\test\VTS_01_1.vob -f avi -vcodec mpeg4 -b 800 -g 300 -bf 2 -acodec mp3 -ab 128 E:\test\test.avi

    ffmpeg shows:
ffmpeg version 0.4.9-pre1, build 4755, Copyright (c) 2000-2004 Fabrice Bellard

  Stream #0.1 -> #0.1
[mpeg4 @ 0068F528]removing common factors from framerate
Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height

    It seems that ffmpeg can not encode mp3, can anyone give me some suggestion?

Best regards.
