Linux下 编译 FFmpeg 支持 G711 + H264 写入 mp4

最近需要将 window 动态库移植到 linux 下，所以在linux下，编译了一下 ffmpeg , 在此记录下编译过程，小伙伴们可以参考借鉴下。

               

 

 1. 编译过程 

1. freetype   https://download.savannah.gnu.org/releases/freetype/  2.9

   1.     ./configure --prefix=/usr/local/freetype

   2.     make -j8

   3.     make install

2. xml2 http://xmlsoft.org/sources/  2.9.8

   1. ./configure  --without-python --prefix=/usr/local/libxml2

   2. make -j8

   3. make install

3. fontconfig https://www.freedesktop.org/software/fontconfig/release/  2.13.92

   1. ./configure  --without-python --prefix=/usr/local/fontconfig

   2. make

   3. make install

4. fribidi  https://github.com/fribidi/fribidi

   1. ./configure --prefix=/usr/local/fribidi

   2. make 

   3. make install

      • 'c2man' is missing on your system.

      • 解决： 修改 .travis.yml  before_script: - ./autogen.sh

5. x264  http://download.videolan.org/pub/videolan/x264/snapshots/

   1. ./configure --enable-shared --enable-static --prefix=/usr/local/x264

   2. make

   3. make install

      • error: x264_bit_depth undeclared (first use in this function) did you mean x264_picture_t

      • 解决: ffmpeg libavcodec->libx264.c 替换 x264_bit_depth -> x264_BIT_DEPTH

6. ffmpeg https://github.com/FFmpeg/FFmpeg 3.1.11

   •  PKG_CONFIG_PATH="/usr/lib/pkgconfig" ./configure --enable-static \
     
         --enable-shared \
     
         --enable-small \
     
         --enable-version3 \
     
         --enable-gpl \
     
         --enable-nonfree \
     
         --enable-libfreetype \
     
         --enable-libfontconfig \
     
         --enable-libfribidi \
     
         --enable-libx264 \
     
         --enable-decoder=h264 \
     
         --enable-encoder=libx264 \
     
         --enable-encoder=pcm_alaw --enable-decoder=pcm_alaw --enable-demuxer=mov --prefix=/usr/local/ffmpeg

      

   • make 

   • make install

 

 2. 注意事项 

1.  将各个类库下的pkg 拷贝到 /usr/lib/pkgconfig/   fontconfig not using in pkgconfig

          eg: cp  /usr/local/fontconfig/lib/fontconfig.pc  /usr/lib/pkgconfig/

     2.  error while loading shared libraries: libx264.so.148: cannot open shared object file: No such file or directory

         cp /usr/local/lib/libx264.so.148 /usr/lib/

 

 3. 结语 

        以上是从我这最强大脑中一点点回忆出来的，如果有不对的地方，大家楼下集合。
