本文目录一览：
安卓 视频会议 开源的源码，有谁可以提供一下吗？
开源码 不难找，可是 视频会议， 不容易吧，要是做开发就去论坛上学习，那里高人比较多。机锋，3G，安卓论坛，贴吧，都可以去看看的
请问那里购买视频会议源代码？
现在视频会议源码价格很便宜的。
CoolVideo视频会议 仿视高,仿好会议.源码比较齐全。
可以在百度里面搜下。
开发一款小视频app源码怎么做？
这种专业的事情还是找专业的团队来做吧！云豹短视频他们家的技术比较强。
想要java写的视频聊天的源代码（供学习）
这个你基本找不到的，这个别人辛辛苦苦把代码写出来是卖钱的，所以你能免费拿到的几率很小，而且有知识产权，就算你拿到了，也只能做学习用，用于商业用途肯定违法的
VB编写视频会议软件
楼上的不要说vb做不了,关键是你不会
这里有个,可以看看
form1中加picture
