ffmpegをMacでコンパイルしたいけど出来なかった備忘録
最新のffmpegをMacでコンパイルしたいと思ってやってみたところ。ハマってますorz。結果的に途中で諦めましたが、その備忘録。
1)MacPortsを使って必要なコーデック等をいれる。
2)1で足したコーデックなどのヘッダファイルを/usr/includeにシンボリックリンクを張る
ln -s /opt/local/include/**/*.h ./
※**/*.hは適当に
3)ffmpegのconfigureを書き換える(libのパスを指定)
# toolchain - cc="gcc" + cc="gcc -L/opt/local/lib" ar="ar"
4)configureをかける。
./configure --enable-libmp3lame --enable-libfaac --enable-libfaad --disable-ffplay --enable-small --enable-memalign-hack --enable-gpl --enable-libxvid --enable-liba52 --disable-vhook --enable-pthreads --enable-libx264
--enable-libamr-nbも入れたかったけどportに何故か無かった。
configureでコケてるようであればconfig.errをチェック、大概はlibが無いとかヘッダファイルが無いと文句を言って来てるはず。
5)makeをする。
今回はここでハマってる。
