# 4.可能遇到的错误 #

Unknown encoder 'libx264'

即，缺少libx264库，需要安装该库：

1. git clone http://git.videolan.org/git/x264.git

2. cd x264

3. ./configure --enable-static --enable-shared

4. make

5. sudo make install

需要重新编译安装ffmpeg

1. 配置ffmpeg时，加上x264，如：

./configure --enable-gpl --enable-libx264

2. make clean --此步骤可以省略

3. make

4. make install

验证：ffmpeg -i input.mp4 -c:v libx264 -c:a copy -f mpegts output.ts

**报错：**

ffmpeg: error while loading shared libraries: libx264.so.159: cannot open shared object file: No such file or directory

修改ld.so.conf文件

1. $ sudo vi /etc/ld.so.conf

2. 修改如下

/usr/local/lib  
include ld.so.conf.d/\*.conf

/usr/local/lib 是x264的库路径

3. 使之生效

$ sudo ldconfig

执行以下命令：

ffmpeg -i input.mp4 -c:v libx264 -c:a copy -f mpegts output.ts

成功！！！
