Darwin Streamer是Apple的开源RTSP服务器，采用APSL(Apple Public Source License)许可协议，可在免费商业使用。
1.下载安装
最新的6.0.3版本只提供源码和mac os上的二进制文件，在windows上用vs无法编译通过。所以使用5.5.5版本
DarwinStreamingSrvr5.5.5-Windows.exe http://static.macosforge.org/dss/downloads/DarwinStreamingSrvr5.5.5-Windows.exe
解压下载的文件， 执行目录中的install.bat进行安装，安装过程中会提供输入管理员用户名和密码，也可以在安装完成后再设置。
还需要安装perl解析器， 下载：http://downloads.activestate.com/ActivePerl/releases/5.14.2.1402/ActivePerl-5.14.2.1402-MSWin32-x86-295342.msi
2.管理配置
打开cmd
设置管理员用户名及密码：
C:\Program Files\Darwin Streaming Server>perl WinPasswdAssistant.pl Darwin Streaming Server Setup In order to administer the Darwin Streaming Server you must create an administrator user [Note: The admin Please enter a new administrator user name: gavin You must also enter a password for the administrator user [Note: The administrator password cannot contai Please enter a new administrator Password: 123456 Re-enter the new administrator password: 123456 Setup Complete!
启动用于管理服务器的web服务器
C:\Program Files\Darwin Streaming Server>perl streamingadminserver.pl
现在在浏览器中输入http://127.0.0.1:1220/，登录管理界面，远程登录时需要验证帐户
在管理界面中，General Settings页面设置视频文件存放目录，默认为C:\Program Files\Darwin Streaming Server\Movies
使用ffplay测试一下自带的示例
ffplay rtsp://192.168.9.80/sample_300kbit.mp4
3.MP4文件的流化
测试发现，只能播放darwin自带的示例文件，自己找的*.mp4文件都不能播放。google发现，需要对MP4文件hint。关于hint，有一段英文解释：
Hint tracks are a series of instructions in a mp4 container file that tell a server how to transmit packets. Hint tracks always refer to another track, most likely an audio or video media track. This series of instructions tells the server when to send the packet, what type of RTP header to add, if there is any extra data in the packet, and how much data to send in the packet. To save on space, a hint can contain a pointer to the media track, instead of duplicating that data. It will also tell what SDP to add for the track that is referenced. So a file that is hinted should have a media track, and an associated hint track for that media track. There are some mp4 container files that just have hint tracks - these are called "fat hints" and are usually not playable locally. These are illegal in ISMA, so we won 't talk about them.
大致的意思是，hint是mp4文件中的轨道，包含了RTP传输所使用的信息，其实就是建立一个索引。网上都说用mp4box可以对mp4文件进行流化操作，下载地址 http://www.videohelp.com/tools/mp4box。mp4box的功能非常多，支持3gp、mp4、avi、mp3等多种文件格式的转换及其它操作，不过它没有转码能力，详细使用参考http://gpac.wp.institut-telecom.fr/mp4box/mp4box-documentation/。不过最后悲剧的发现，出错了：
F:\Video>mp4box -hint 3.mp4
Hinting file with Path-MTU 1450 Bytes
Cannot create hinter (Feature Not Supported)
Error: Feature Not Supported
又找了一个名为mp4creator的工具，下载地址http://mp4creator.sourceforge.net/download/index.htm
F:\Video>mp4creator -list Gucci.mp4 Track Type Info 1 video H264 Baseline@3, 24.920 secs, 2407 kbps, 800x608 @ 25.000000 fps 2 audio MPEG-4 AAC LC, 24.938 secs, 126 kbps, 44100 Hz F:\Video>mp4creator -hint Gucci.mp4 MP4ERROR: FindTrackIndex: Track id 0 doesn't exist mp4creator: couldn't create hint track, no media samples 出错了！！！试试对单个轨道进行hint F:\Video>mp4creator -hint=1 Gucci.mp4 MP4ERROR: MP4File::FindIntegerProperty: no such property - moov.trak[0].mdia.minf.stbl.stsd.*.esds.decConfigDescr.objectTypeId MP4ERROR: MP4File::FindIntegerProperty: no such property - moov.trak[2].mdia.minf.stbl.stsd.*.esds.decConfigDescr.objectTypeId F:\Video>mp4creator -list Gucci.mp4 Track Type Info 1 video H264 Baseline@3, 24.920 secs, 2407 kbps, 800x608 @ 25.000000 fps 2 audio MPEG-4 AAC LC, 24.938 secs, 126 kbps, 44100 Hz 3 hint Payload H264 for track 1 虽然hint过程中，有错误提示但还是成功添加了hint轨道 F:\Video>mp4creator -hint=2 Gucci.mp4 MP4ERROR: MP4File::FindIntegerProperty: no such property - moov.trak[0].mdia.minf.stbl.stsd.*.esds.decConfigDescr.objectTypeId MP4ERROR: MP4File::FindIntegerProperty: no such property - moov.trak[2].mdia.minf.stbl.stsd.*.esds.decConfigDescr.objectTypeId MP4ERROR: MP4File::FindIntegerProperty: no such property - moov.trak[3].mdia.minf.stbl.stsd.*.esds.decConfigDescr.objectTypeId F:\Video>mp4creator -list Gucci.mp4 Track Type Info 1 video H264 Baseline@3, 24.920 secs, 2407 kbps, 800x608 @ 25.000000 fps 2 audio MPEG-4 AAC LC, 24.938 secs, 126 kbps, 44100 Hz 3 hint Payload H264 for track 1 4 hint Payload mpeg4-generic for track 2
对音视频轨道单独进行hint才能成功，提示的错误暂时不明白是什么原因，不过用vlc2.0测试过，转换后的视频能正常播放。但是用ffplay和mplay播放时，均存在问题。
