【1】mplayer

1.将mplayer放到开发板的bin目录下

system(“mplayer 1.avi &”); // &为后台播放视频

播放音乐SEO靠我

system(“madplay -a -10 xxx.mp3”);//-a 音量控制范围（-175~+18）

暂停播放

system(“killall -STOP madplay &”);

恢复播放

sysSEO靠我tem(“killall -CONT madplay &”);

停止

system(“killall madplay”);

madplay终止

system(“killall -9 madplay”);

思路 SEO靠我：如何保证将电脑的音频或视频传输给开发板，保持数据完整

1.先发送文件大小 2.再发送数据内容 3.检测发送的数据与接收的数据大小是否一致
