編譯

1. librtmp

cd rtmpdump
make
make install

2. yasm

cd yasm
./configure --prefix=/usr/local/yasm
make
make install

3. libx264

cd x264
./configure --prefix=/usr/local/x264 --enable-shared --enable-static --enable-yasm
make
make install

4. libfaac

apt-get install libfacc-dev

5. ffmpeg

cd ffmpeg
./configure --prefix=/usr/local/ffmpeg --enable-shared --enable-libx264 --enable-gpl --enable-pthreads --extra-cflags=-I/usr/local/x264/include --extra-ldflags=-L/usr/local/x264/lib
make
make install

可能出現的問題

1. libx264 not found等類似的庫找不到

1. –extra-cflags=-I 和 –extra-ldflags 手動指定標頭檔案和庫路徑

2. 將使用到的庫路徑新增至PATH中

   vim /etc/profile  //檔案末尾加入下面內容
   
   export PATH=/usr/local/bin:$PATH
   export PATH=/usr/local/yasm/bin:$PATH
   export PATH=/usr/local/yasm/lib:$PATH
   export PATH=/usr/local/x264/bin:$PATH
   export PATH=/usr/local/x264/include:$PATH
   export PATH=/usr/local/x264/lib:$PATH
   export PATH=/usr/local/sbin:$PATH
   export PATH=/usr/local/bin:$PATH
   export
    
    PATH=/usr/sbin:$PATH
   export PATH=/sbin:$PATH
   export PATH=/usr/local/lib:$PATH
   
   //儲存退出
   source /etc/profile
   ldconfig

2. error while loading shared libraries: libx264.so: cannot open shared object file: No such file

    vim /etc/ld.so.conf
    ...
    /usr/local/lib
    /usr/local/x264/lib //新增x264庫路徑，新增完儲存退出
    ldconfig

測試

ffmpeg -v //檢視ffmpeg版本
ffmepg    //測試ffmpeg執行是否缺少庫引用
ffmpeg -i 'rtmp://192.168.1.12/live/livestream live=1' -vcodec copy -acodec copy -f flv -y rtmp://192.168.1.12/live/livestream1 //測試ffmpeg是否可以使用librtmp轉rtmp流
