#Installing FFmpeg:
1. Type `./configure` to create the configuration. A list of configure
options is printed by running `configure --help`.
`configure` can be launched from a directory different from the FFmpeg
sources to build the objects out of tree. To do this, use an absolute
path when launching `configure`, e.g. `/ffmpegdir/ffmpeg/configure`.
2. Then type `make` to build FFmpeg. GNU Make 3.81 or later is required.
3. Type `make install` to install all binaries and libraries you built.
NOTICE
------
- Non system dependencies (e.g. libx264, libvpx) are disabled by default.最后发现并没有编译出ffplay,在使用ffplay播放视频的时候没有找到ffplay.然后查看configure生成的config.mak文件,发现其中的关于
FFPLAY的一行前面有感叹号：
!CONFIG_FFPLAY=yes
也就是在生成配置文件时由于某些原因并没有成功生成编译ffplay的配置，最后查找原因是由于缺少了1个库：
sdl2.0
解决办法：
brew install sdl2
brew link sdl2
