文章【Android 的视频编码 H263 MP4V H264】的代码实现

转载地址：http://blog.csdn.net/zblue78/article/details/6083374

此篇文章所述代码，我没有能正常用socket发送视频。我上上篇文章所讲述的代码，是我跑通并且能正常用socket存储视频文件的代码。

CSDN代码地址，能正常运行： http://download.csdn.net/detail/cooler126/5777745
最近很多同学问我SPS和PPS在那里设置，其实这篇文章只是我 上篇文章的一个简单实现

具体情况情看看上一篇
http://blog.csdn.net/zblue78/archive/2010/12/15/6078040.aspx
这里只用HTC的G7做了H264的程序，谅解！

csdn的资源慢了 粘代码算了

欢迎大家经常访问我的blog http://blog.csdn.net/zblue78/
共同探讨，啥也不说的 直接上码
