基于red5 dsj 的java 处理视频流和一些疑问

最近夭折了一个项目，由于我预研失败，同时我将被惩罚，被外派去其他公司干活，干完再回来。

下面来说说这个项目。最后再总结为什么失败。

基于red5的视频聊天，桌面共享。下图是简单的逻辑图

 

做视频聊天，做桌面共享，而且要在手机端也能显示出来，因此采用red5 这个开源的流媒体服务器。

 

公司的产品是典型的基于服务的多客户端模式。

简单的说是一个java后台发布服务，客户端有windows桌面版（java）；mac桌面（java）；android；ios,由于是自动化办公，所以集成了im，office,网盘等等功能。

 

下面看看怎么玩的。

1  dsj 这是微软的dictShow的java 版，免费使用，非开源

下载下来以后里面有个dsj.dll放如c盘 system32里面。

/**
Updated for 0_8_6

Demonstrates changing formats delivered by a capture device before and after the filtergraph is built.
Configuration before building the graph is done via a ready made dialog, whose source-code can be found in the
main dsj demo.

dsj 0_8_51 adds some missing functionality to address single output pins on capture devices with separate capture
and preview pins. This makes things a little more complex, but finally also takes hardware reality into account
after the graph is built.
0_8_6 intoduces the setCropSize method, which enables fine grain control of output sizes with devices, that
otherwise only offer limited choice of dimensions with their supported formats. This mostly applies to the more
professional capture boards and cameras. For example Viewcast Osprey boards or IDS Ueye cameras will only have one
dimension to select from, but then can shrink and / or crop from that. There is no clear standard, so the
implementation is driver specific.
Also new in 0_8_6 are api methods to configure analog video digitizers.

这个类是有问题的，接受的到的流无法显示，可能需要转化成某种格式。

 

由于是匆匆整理，省略了red5 的安装，red5跟tomcat 一样使用起来简单，openmeetings 中的屏幕共享代码我是copy他的做一些修改，但是怎么去用java将他显示？不知道。要是用flex 简直soeasy.明天整理完再写上完整版的，希望本坛神人能help me ! 不然心里有个坎，过不去！！
