live555的使用（转载）

Live555 是一个为流媒体提供解决方案的跨平台的C++开源项目，它实现了对标准流媒体传输协议如RTP/RTCP、RTSP、SIP等的支持。Live555实现 了对多种音视频编码格式的音视频数据的流化、接收和处理等支持，包括MPEG、H.263+、DV、JPEG视频和多种音频编码。同时由于良好的设 计，Live555非常容易扩展对其他格式的支持。目前，Live555已经被用于多款播放器的流媒体播放功能的实现，如VLC(VideoLan)、 MPlayer。下面介绍Live555的基本使用方法。

编译

编译方法：

./genMakefiles <os-platform>

如在Linux 下解压Live555后进入目录：

#./genMakefiles linux

#Make

使用

1）进入mediaServer目录启动服务器：

[root@localhost mediaServer]# cd mediaServer]

[root@localhost mediaServer]# ./live555MediaServer

LIVE555 Media Server

version 0.5 (LIVE555 Streaming Media library version 2010.07.29).

Play streams from this server using the URL

rtsp://192.168.1.120/<filename>

where <filename> is a file present in the current directory.

Each file's type is inferred from its name suffix:

".aac" => an AAC Audio (ADTS format) file

".amr" => an AMR Audio file

".m4e" => a MPEG-4 Video Elementary Stream file

".dv" => a DV Video file

".mp3" => a MPEG-1 or 2 Audio file

".mpg" => a MPEG-1 or 2 Program Stream (audio+video) file

".ts" => a MPEG Transport Stream file

(a ".tsx" index file - if present - provides server 'trick play' support)

".wav" => a WAV Audio file

See http://www.live555.com/mediaServer/ for additional documentation.

2）进入testProgs使用客户端工具播放mp3

[root@localhost testProgs]# ./openRTSP rtsp://192.168.1.120/1.mp3
