vlc转码出现的问题

秋分中的雨 2013-12-19 01:57:00

要实现的是把从摄像头获取的数据编码生成流，然后在页面显示，协议是rtsp的，拼接的转码流是
private static String formatRtspStream(String serverAddress, int serverPort, String id) {
StringBuilder sb = new StringBuilder(60); sb.append(":sout=#transcode{vcodec=h264,vb=2200,scale=1,fps=30,acodec=mp4a,ab=128,channels=2,samplerate=44100,aspectRatio=4:3,width=720,height=640} :es{access=udp,mux=ts,dst=");
sb.append(serverAddress);
sb.append(':');
sb.append(serverPort);
sb.append('/');
sb.append(id);
sb.append("}");
return sb.toString();
}
播放参数是：
options = formatRtspStream("192.168.1.113", 5577, ss);
mediaPlayer.playMedia(media,
options,
":no-sout-rtp-sap",
":no-sout-standard-sap",
":sout-all",
":sout-keep");
运行视频可以出来，就是时间不是一秒一秒走的，控制台打印是

没看懂是什么原因，求指教啊。
