mencoder インストール

mencoderはMPlayerをインストールすると一緒に入るのでそうします
http://www.mplayerhq.hu/MPlayer/releases/　ここからダウンロード
　・MPlayer-1.0pre8.tar.bz2
　・all-20060501.tar.gz

mkdir /usr/local/src/win32
tar xvzf all-20060501.tar.gz
mv all-20060501/* /usr/local/src/win32/

tar jxvf MPlayer-1.0pre8.tar.bz2
cd MPlayer-1.0pre8

./configure --confdir=/etc/mplayer --disable-gui --language=ja --with-win32libdir=/usr/lib/src/win32 --enable-qtx --enable-external-faad --enable-win32 --enable-libavcodec --disable-libavformat --enable-amr_nb --enable-amr_nb-fixed --enable-amr_wb --enable-mp3lib

エラーがでます
==============================================

==============================================

ffmpeg のときにつくった3gp関連のディレクトリを全部コピー
cp -R /usr/local/src/FFMpeg-20050806/libavcodec/amr_float /usr/local/src/MPlayer-1.0pre8/libavcodec/
cp -R /usr/local/src/FFMpeg-20050806/libavcodec/amr /usr/local/src/MPlayer-1.0pre8/libavcodec/
cp -R /usr/local/src/FFMpeg-20050806/libavcodec/amrwb_float /usr/local/src/MPlayer-1.0pre8/libavcodec/

これで再度　config, make

makeでエラー

===============================================

さらにコピー　＊上書きします
cp /usr/local/src/FFMpeg-20050806/libavcodec/libavcodec.a /usr/local/src/MPlayer-1.0pre8/libavcodec/

make
make install

これでインストールできた！
