3.另外一台客户端PC，使用VLC可以测试FFmpeg服务器
VLC菜单栏->媒体->打开网络串流，就可以正常播放HTTP服务器流媒体了。
或者外网测试：
编译完成后，自然希望能我们有所作用，否则也不会没事编译ffmpeg。
1.把视频的前120帧转换成一个gif图，大小指定为230*450：
ffmpeg -i device-2016-08-25-193402.mp4 -vframes 120 -s 230x405 -y -f gif Super3.gif
2.调用ffmpeg命令将一个视频转成3gp格式：
ffmpeg -i device-2016-08-25-193402.mp4 -y -b 20 -s sqcif -r 10 -acodec amr_wb -ab 23.85 -ac 1 -ar 16000 video.3gp
