解决rtmpdump: error while loading shared libraries: librtmp.so.1

1.执行
git clone git://git.ffmpeg.org/rtmpdump
2.make
3.执行rtmpdump -v
rtmpdump: error while loading shared libraries: librtmp.so.1: cannot open shared object file: No such file or directory

缺少库librtmp.so.1

执行make install
如下
make[1]: Entering directory `/home/vagrant/rtmpdump/librtmp'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/home/vagrant/rtmpdump/librtmp'
mkdir -p /usr/local/bin /usr/local/sbin /usr/local/man/man1 /usr/local/man/man8

cp librtmp.a /usr/local/lib
cp librtmp.pc /usr/local/lib/pkgconfig
cp librtmp.3 /usr/local/man/man3
cp librtmp.so.1 /usr/local/lib  库安装到这个目录
cd /usr/local/lib; ln -sf librtmp.so.1 librtmp.so

解决办法：
cd /etc/ld.so.conf.d 增加rtmpdump的依赖lib库的路径

执行 
echo "/usr/local/lib/" > rtmpdump-x86_64.conf

执行 ldconfig 

再执行
 ldd `which rtmpdump`

        librtmp.so.1 => /usr/local/lib/librtmp.so.1 (0x00007fd3eb6e1000)   有了

再验证
