CentOS 6.5 x64安装FFmpeg

CentOS 6.5 安装 ffmpeg
满满的坑

安装ffmpeg

1.安装依赖包

yum -y install yasm（建议源码安装）
yasm-1.3.0.tar.gz（安装高版本的x264可能会提示需要1.2以上的yasm）

2.安装x264（卸载了yum安装的软件包）

http://download.videolan.org/pub/videolan/x264/snapshots/ http://download.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20170213-2245-stable.tar.bz2 tar -jxf x264-snapshot-20170213-2245-stable.tar.bz2
cd x264-snapshot-20170213-2245-stable/
./configure --enable-shared
make
make install

3.安装ffmpeg

https://ffmpeg.org/releases/ffmpeg-3.2.7.tar.gz
tar -zxf ffmpeg-3.2.7.tar.gz
cd ffmpeg-3.2.7
./configure --prefix=/usr/local/data/ffmpeg --enable-shared --enable-libx264 --enable-gpl
make
make install

注：

ERROR: libx264 must be installed and version must be >= 0.118.
#如果出现这个错误,需要安装高版本的x264（但后面，可能版本会跟ffmpeg要求的不符合，看情况而定）

/usr/local/data/soft/ffmpeg/libavcodec/libavcodec.a(libx264.o): In function `X264_init':
/usr/local/data/soft/ffmpeg/libavcodec/libx264.c:305: undefined reference to `x264_encoder_open_148'
collect2: ld returned 1 exit status
make: *** [ffmpeg_g] Error 1
#这个错误，莫名好了

Error: can't open /tmp/ccplUYXy.s for reading: No such file or directory
make: *** [libavcodec/ffv1enc.o] Error 1
#重新make下就好了

[root@localhost ~]# ffmpeg -version
ffmpeg: error while loading shared libraries: libavdevice.so.57: cannot open shared object file: No such file or directory
#编辑/etc/ld.so.conf 添加/usr/local/data/ffmpeg/lib  然后ldconfig

ffmpeg -version
ffmpeg: 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/

遇到的问题：
ffmpeg --version 提示找不到库文件

http://downloads.videolan.org/pub/videolan/x264/snapshots/ http://downloads.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20101111-2245.tar.bz2

这里安装是最新版， 导致库文件是.so.148





安装好了，然后做一个复制一个libx264.so.107 到/usr/lib/下即可



测试：

ffmpeg -i 5311bde54a656.mov -c:v libx264 -pix_fmt yuv420p -movflags faststart 456.mp4
