Use Lffmpeg to play HLS stream below Linux

Ffplay playback relies on the SDL library, and SDL (Simple DirectMedia Layer) is a set of open source cross-platform multimedia development libraries. First compile the SDL and then compile the ffmpeg.

1. SDL compiled installation./configure--prefix=/xxx && make && make install
2. FFmpeg compile and install./configure --prefix=/opt/afb/ffmpeg/dir_install--enable-debug--disable-stripping-- Disable-optimizations--disable-doc --disable-ffmpeg--disable-ffprobe--disable-ffserver && make && Amp Make install && CP/*/*.a*/opt/afb/ffmpeg/dir_install/lib/(copy library file to use GDB Debug for unknown reason)
