Finally, download and install ffmpeg
I use svn to synchronize data. If the data cannot be compiled, consider not to use the latest one. However, please note that you are connecting to this website, it was killed by the firewall in our country. You need to think about it yourself.
Svn checkout svn: // svn. mplayerhq. hu/ffmpeg/trunk ffmpeg

Update Dynamic Link Library
Because it is installed by the compiler, the system needs to find the dynamic link library.
# Echo "/usr/local/lib">/etc/ld. so. conf
# Echo "/usr/lib">/etc/ld. so. conf
# Ldconfig
The installation is complete.
