编译ffmpeg 2.6.3 h264

需要:

x264的库,直接去下载回来 编译就可以了.

git clone git://git.videolan.org/x264.git
 ls
 cd x264/
 ls

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

然后去配置

ffmpeg的configure

#!/bin/sh


function build_one {
	./configure  \
		--prefix=$PREFIX  \
		--cc=clang \
		--disable-yasm \
		--enable-gpl \
		--enable-libx264 \
		--extra-cflags=-I/Users/jack/Downloads/ffmpeg/x264/build/include \
 		--extra-ldflags=-L/Users/jack/Downloads/ffmpeg/x264/build/lib \


}

PREFIX=$(pwd)/build

build_one

注意这个configure指令是不能有空行的,空行一定要用 "\"来接上.

看输出有没有启用了h264库

启用了 就直接make&make install 完成ffmpeg的编译.

使用ffmpeg吧h264 转 MP4

./ffmpeg -i XXX.h264 out.MP4
